Introduction

Overview

Topcon Positioning System’s HiPer Lite and HiPer Lite+ receivers
are dual-frequency, GPS+ receivers built to be the most advanced
and compact receiver for the surveying market. The HiPer Lite and
HiPer Lite+ are multi-function, multi-purpose receivers intended
for precision markets. Precision markets means markets for
equipment, subsystems, components and software for surveying,
construction, commercial mapping, civil engineering, precision
agriculture and land-based construction and agriculture machine
control, photogrammetry mapping, hydrographic and any use
reasonably related to the foregoing.

The HiPer Lite and HiPer Lite+ can receive and process both L1
and L2 signals, improving the accuracy of your survey points and
positions. The dual-frequency and GPS+ features of HiPer Lite and
HiPer Lite+ combine to provide the only real time kinematic (RTK)
system accurate for short and long baselines. Several other features,
including multipath mitigation and co-op tracking, provide under­canopy and low signal strength reception. The receivers pro vide the
functionality , accuracy, availability, and integrity needed for fast
and easy data collection.

Principles of Operation

Surveying with the right GPS receiver can provide users accurate
and precise positioning, a requirement for any surveying project.

This section gives an overview of GPS and receiver functions to
help you understand and apply GPS principles, allowing you to get
the most out of your receiver.

GPS Overview

The Global Positioning System (GPS) is a satellite-based, line­of-sight radio navigation system run by the United States
Department of Defense (DoD). This system offers a global, all
weather, 24-hour positioning, velocity, and time service to any

Topcon HiPer Lite and HiPer Lite+ Operator’s Manual

Principles of Operation

user equipped with a GPS tracking receiver, who is on or near
the Earth’s surface. The Global Navigation Satellite System
(GLONASS), is the Russian Federation Ministry of Defense
counterpart to GPS. At any one time, with a standard 15 degree
angle, up to 10 or 12 GPS satellites are visible from any point
on earth. When a receiver can also track GLONASS satellites,
between 10 and 16 satellites are visible.

For information on the current status of the GPS constellation,
visit http://tycho.usno.navy.mil/ or
http://www.navcen.uscg.gov/. For GLONASS, visit
http://www.glonass-center.ru/frame.html.

Despite numerous technical differences in the implementation
of these systems, both GPS and GLONASS ha ve three essential
components:

• Space – GPS and GLONASS satellites orbiting

approximately 12,000 nautical miles above Earth and are
equipped with a clock and radio. These satellites broadcast
digital information (ephemerides, almanacs, time frequency
corrections, etc.).

• Control – Ground stations located around the Earth that

monitor the satellites and upload data, including clock
corrections and new ephemerides (satellite positions as a
function of time), to ensure the satellites transmit data
properly.

• User – The community and military that use GPS/

GLONASS receivers and the corresponding satellites to
calculate positions.

P/N 7010-0557 www.topconpositioning.com

1-3

Introduction

Calculating Positions

Once the receiver locks on to a satellite, it starts recording
measurements and receiving the various digital information
(ephemeris, almanac, and so on) the satellites broadcast. To
calculate a position, receivers use the following formula:

Velocity x Time = Distance

Where Velocity is the speed at which radio waves travel
(i.e., the speed of light) and Time is the difference between
the signal transmission time and signal reception time.

To calculate absolute 3-D positions—latitude, longitude,
altitude—the receiver must lock on to four satellites. In a
mixed, GPS and GLONASS scenario, receiver’s must lock
onto at least five satellites to obtain an absolute position.

To provide fault tolerance using only GPS or only
GLONASS, the receiv er must lock onto a f ifth satellite. Six
satellites will provide fault tolerance in mixed scenarios.
Usually, the number of GPS and GLONASS satellites in
view does not exceed twenty (20).

1-4

Once locked on to a satellite, the receiver collects
ephemerides and almanacs, saving this information to its
NVRAM (Non-Volatile RAM).

• GPS and GLONASS satellites broadcast ephemeris
data cyclically, with a period of 30 seconds.

• GPS satellites broadcast almanac data cyclically with a
period of 12.5 minutes; GLONASS satellites broadcast
almanac data cyclically with a period of 2.5 minutes.

Topcon HiPer Lite and HiPer Lite+ Operator’s Manual

Principles of Operation

GPS Positioning

Achieving quality position results requires the following
three elements:

• Accuracy – The accuracy of a position depends upon

the number, signal integrity, and placement (also
known as Dilution of Precision, or DOP) of satellites.

–Differential GPS (DGPS) strongly mitigates
atmospheric and orbital errors, and counteracts anti­spoofing signals the US Department of Defense
transmits with GPS signals.

–The more satellites in view , the stronger the signal, the
lower the DOP number, providing more accurate
positioning.

• Availability – The availability of satellites affects the

calculation of valid positions. The more visible
satellites available, the more valid and accurate the
position. Natural and man-made objects can block,
interrupt, and weaken signals, lowering the number of
available satellites.

• Integrity – Fault tolerance allows a position to have

greater integrity, increasing accuracy. Several factors
combine to provide fault tolerance, including:

–Receiver Autonomous Integrity Monitoring (RAIM)
detects faulty GPS and GLONASS satellites and
removes them from the position calculation.

–Wide Area Augmentation System (WAAS) creates
and transmits DGPS correction messages.

–Five or more visible satellites for only GPS or only
GLONASS; six or more satellites for mixed scenarios.

–Current ephemerides and almanacs.
–Several algorithms to detect and correct faulty

information.

Introduction

Conclusion

Surveyors can use Topcon GPS+ receivers to collect data
from a network of satellites and control stations to
triangulate precise points anywhere on Earth.

This overview simply outlines the basics of GPS and
GLONASS positioning. For more detailed information,
visit the TPS website (www.topconps.com/gpstutorial/).

Receiver Overview

When power is turned on and the receiver self-test completes,
the receiver’s 20 channels initialize and begin tracking visible
GPS satellites. Each of the receiver’s channels can be used to
track C/A-L1, P-L1, or P-L2 signals. The number of channels
available allo ws the recei ver to track all visible GPS satellites at
any time and location. The GPS antenna receives the different
signals for processing.

An internal GPS antenna equipped with a low noise amplifier
(LNA) and the receiver’s radio frequency (RF) device are
connected with a coaxial cable. The wide-band signal received
is down-converted, filtered, digitized, and assigned to different
channels. The receiver processor controls the process of signal
tracking.

1-6

Once the signal is locked in the channel, it is demodulated and
necessary signal parameters (carrier and code phases) are
measured. Also, broadcast navigation data are retrieved from
the navigation frame.

After the receiver locks on to four or more satellites, it is
possible to solve the so-called “absolute positioning problem”
and compute the receiver’s coordinates (in WGS-84) and time.
All this information is stored in the receiver’s memory, which
can be downloaded later onto a computer and processed using a
post-processing software package. When the receiver is run in
RTK mode, raw data measurements can also be recorded into

With Bluetooth wireless technology, the receiver’s
reception and transmission distance is 10 meters (32 feet)
for interior projects and 30–50 meters (98–164 feet) for
exterior projects.

The Bluetooth module’s processor and firmware are
independent of the receiver card and power board.

Radio Modem

The receiver incorporates an internal, spread spectrum, 915
MHz modem for receiving data from a Base station or
transmitting data to a Rover station. The Base station’s
modem transmits the carrier phase and code measurements
along with the reference station information (i.e., location)
to the Rover station modem.

Topcon HiPer Lite and HiPer Lite+ Operator’s Manual

Getting Acquainted

The internal radio modem comes with a number of preset
channels programmed at TPS. Complete information
regarding the radio system can also be found in the radio
modem’s documentation.

Power Board

The internal power board manages receiver power and
battery charging, and is connected to the receiver board and
the batteries. The power board receives power from the
internal batteries, even when the receiver is turned of f. This
feature allows the internal batteries to charge, regardless of
the receiver’s status (on or off). To prevent the batteries
from discharging when the receiver is stored, put the
receiver in Zero Power Mode (see “Zero Power Mode” on
page 4-21 for more information). The batteries will not
charge in this mode.

The power board’ s processor and firmware are independent
of the receiver card. To ensure firmware compatibility, the
GPS receiver board and power board must be loaded with
firmware from the same package.

GPS+ Receiver Board

The receiver is supplied with one of the following receiver
boards:

• Euro-80 card for HiPer Lite receivers

• Euro-112 card for HiPer Lite+ receivers

Depending on the purchased options, these cards are
capable of processing the following signals:

• GPS L1 or GPS L1/L2

• GPS/GLONASS L1 or GPS/GLONASS L1/L2

Table 1-2 on page 1-14 lists the options available for these
cards.

MINTER Configuration

Recording Interval parameter

This parameter specifies the message output interval into the
log file when the MINTER FN key (pressed for 1–5 seconds)
activates data logging. This setting is used for both logging a
single log file, and logging receiver data in AFRM mode.
Values are 1–86400 seconds.

The default value is one second.

Elevation Mask for Log File parameter

This parameter specifies the minimum elevation angle for the
satellites whose data will be put in the receiver files logged
when pressing FN.

The default value is five degrees.

File Name Prefix parameter

This parameter specifies the prefix added to the names of
receiver files created when pressing FN. The pref ix can be up to
20 characters long.

The default value for the Name Prefix is log.
Log file names have the following structure:

<prefix><month><day><sequential alphabet letter>

The file name depends on both the file creation time (month
and day) and additional letter suffixes to avoid confusion
between files created on the same day.

Always Append to the File parameter

If you want new receiver data to be appended to an existing log
file, enter the desired file name in this parameter. The setting
can be up to 20 characters long.

P/N 7010-0557 www.topconpositioning.com

2-25

Configuration

Files Creation Mode parameter

This parameter has two possible operation modes:

• Log file – If the log file radio button has been selected,

pressing the FN key closes the current log file. If data
logging is off, pressing FN opens a new log file.

• AFRM – If AFRM radio button has been selected, pressing

FN enables this mode. If AFRM has been enabled, pressing
FN disables this mode.

Automatic File Rotation Mode (AFRM) parameters

TPS receivers are capable of automatically rotating log files.
During a “file rotation” event, the receiver closes the current
file and opens a new one according to a user-defined schedule.
The Period and Phase parameters specify this schedule. File
rotation launches the moment the receiver time module Period
is equal to Phase. More precisely, a new log file opens
immediately before the scheduled epoch causing data tagged
with this epoch to be recorded to the new log file.

2-26

When opening a new log file, the receiver enables the default
set of messages outputted with the default output period. Both
the default set of messages and the default output period are
programmable.

• Period – specifies the time duration of each log file created in
AFRM mode.

Values are 60 to 86400 seconds. The default value is 3600
seconds.

• Phase – specifies the “phase” (constant time shift) of creating
multiple log files in AFRM mode.

Values are 0 to 86400 seconds. The default value is zero
seconds.

• Files (total) – a counter that specifies how many multiple log
files must be created in AFRM until this mode automatically

Topcon HiPer Lite and HiPer Lite+ Operator’s Manual

MINTER Configuration

turns off. This counter decrements on every file rotation until it
value becomes zero, then file rotation automatically stops. The
counter initializes with AFRM.

Note that a log file opens immediately after turning AFRM on.
This startup file is not considered a file rotation event; the
AFRM counter will not decrement.

Values are 0 to [2

31

-1]. The default value is 0 (zero). Zero

means that an unlimited number of log files will be created.

NOTICE

NOTICE

The receiver’s memory holds up to 512 files.

• Files (remain) – specifies the number of files left for the

receiver to create in AFRM.

31

Values are 0 to [2

-1]. The default value is zero.

• Automatically remove old files – when no free memory is

available to log data, automatically remo ves the earliest log f ile.
If this parameter is enabled, your receiver will erase the file
with the earliest file creation time/date. AFRM must be enabled
to use this FIFO (First-In, First-Out) feature.

The default value is off (disabled).

FN Key Mode parameter

Use these two radio buttons to program how the receiver will
react when pressing the FN key.

• LED blink mode switch – pressing FN will toggle between

the MINTER’s normal/extended information modes and
start/stop data recording of Static survey.

– FN pressed for less than 1 second: changes the
information mode (Normal or Extended Information
(EI) Modes).

2-27

P/N 7010-0557 www.topconpositioning.com

Configuration

– FN pressed for 1 to 5 seconds: starts or stops data
recording (Static post-processing mode).

• Occupation mode switch – pressing FN (less than one

second) will insert into the corresponding log file a
message indicating that the survey type has been changed
from static to kinematic, or vice versa. If the REC LED
blinks green, the current mode is dynamic, if it blinks
orange, the current mode is static. For more details, see
Table 4-1 on page 4-5, and refer to the MINTER User’s
Manual and PC-CDU User’s Manu al .

Initial Data Collection Dynamic Mode parameter

These radio buttons specify the starting occupation type
descriptor inserted at the beginning of receiver files logged.
Select Static or Kinematic to specify that the corresponding log
file will start with a static (STOP) or kinematic (GO,
Trajectory) occupation, respectively.

Data Recording Auto-start parameter

These radio buttons allow you to program your receiver’s
behavior in the event of a power failure.

Collecting Almanacs

Collecting Almanacs

Each satellite broadcasts a message (almanac) which gives the
approximate orbit for itself and all other satellites. If the receiver
has an almanac, you can considerably reduce the time needed to
search for and lock on to satellite signals.

The receiver regularly updates the almanac and stores the most
recent almanac in its Non-Volatile Random Access Memory
(NVRAM).

1. Set up the receiver (connect the external antenna, if needed) in a
location with a clear view of the sky.

2. Turn on the receiver.

3. Wait for about 15 minutes while the receiver collects almanac
data from the satellites.

NOTICE

NOTICE

If 15 minutes have passed and the receiver does not lock
on to satellites, you may need to clear the NVRAM. See
“Clearing the NVRAM” on page 4-18 for this procedure.

You will need to collect or update the almanac:

• If the receiver has been off for a long time.

• If the last known receiver position, stored in the NVRAM, is
different from the present position by several hundred
kilometers.

• After loading a new OAF.

• After loading new firmware.

• After clearing the NVRAM.

• Before surveying.

Setup and Survey

This chapter describes:

• Receiver setup

• RTK Base station setup

• RTK Rover setup

• Basic surveying with the HiPer Lite or HiPer Lite+ receiver

The HiPer Lite and HiPer Lite+ packages use one receiver as the
Base station and the other as the Rover station.

Receiver Setup

To set up the receivers, you must:

1. Configure the receivers as shown in Chapter 2.

2. Set up the Base and Rover stations. See “Step 1: Set up the
Receiver” on page 3-2.

3. Measure the antenna height. See “Step 2: Measure Antenna
Height” on page 3-2 for internal antennas.

4. Begin collecting data. See “Step 3: Collect Data” on page 3-4.

All receivers include an internal, micro-strip antenna able to capture
L1/L2 signals from GPS and GLON ASS satellites.

P/N 7010-0557 www.topconpositioning.com

Setup and Survey

Step 1: Set up the Receiver

This section assumes the receiver has been configured using
PC-CDU.

1. Place the receiver on the appropriate tripod or bipod.

2. Center the receiver over the point at which data will be
collected. For most applications, this should be at a location
with a clear view of the sky.

Step 2: Measure Antenna Height

The location of the antenna relative to the point being measured
is very important for both surveys in which the elevation of the
points is important and in surveys for horizontal location only.
Horizontal surveys are often larger in area than can reliably fit
on a flat plane, therefore the antenna adjustment must be done
in three dimensions and then projected onto a two dimensional
plane.

The receiver calculates the coordinates of the antenna’s phase
center. To determine the coordinates of the station marker, the
user must specify the following:

3-2

• Measured height of the antenna above the station marker

• Method of measuring the antenna height

• Model of the antenna used

Antennas have two types of measurements:

• Vertical – measured from the marker to the antenna
reference point (ARP) located on the bottom of the receiver
at the base of the mounting threads.

• Slant – measured from the marker to the lower edge of the
antenna slant height measure mark (SHMM) located on
both end panels of the receiver.

Topcon HiPer Lite and HiPer Lite+ Operator’s Manual

Receiver Setup

1. Measure the antenna height above the point or marker.
Figure 3-1 illustrates the antenna offsets. (See Figure 1-5

on page 1-17 and Figure 1-7 on page 1-19 for the exact
SHMM location.)

30.50mm

Table 3-1gives the offset values for the receivers.

Table 3-1. Antenna Offset Values for Receiver Options

To L1 Phase Center To L2 Phase Center

Up 106.1mm 95.7mm

The point to which surveying with GPS/GLONASS
measures is called the Phase Center of the antenna. This is
analogous to the point at which a distance meter measures
in a prism. A user must enter the prism offset to
compensate for this point not being at a physical surface of
the prism. In the case of a GPS/GLONASS antenna, the
offset is entered depending on the type of measurement
taken. For vertical, the offset is simply added to the
measured vertical height to produce a “true” v ertical height.
For slant height, the vertical height must first be calculated

3-3

P/N 7010-0557 www.topconpositioning.com

Setup and Survey

using the radius of the antenna, then the offset can be
added. The offsets are not the same number because of the
difference in location between the slant measuring point
and the vertical measuring point.

2. Record the antenna height, point name, and start time in the
field notes.

3. Press the power key and release it to turn the receiver on.
The STAT (status) light (LED) will blink red at first.

4. Once the receiver has locked on to one or more satellites,
the STAT light will blink green for GPS satellites, orange
for GLONASS satellites, and a short red blink indicating it
has not solved a position. Four or more satellites provide
optimal positioning.

5. Once the short red blink is gone, the receiver has a position
and surveying can begin. You should wait for green and
orange lights before beginning data collection. This ensures
that the receiver has the correct date and time, and is locked
on to enough satellites to ensure good quality data.

3-4

The process of locking on to satellites normally takes less
than one minute. In a new area, under heavy tree canopy, or
after resetting the receiver, it may take several minutes.

Step 3: Collect Data

1. To begin collecting data, press and hold the FN (function)
key for more than one second and less than five seconds.

2. Release the FN key when the REC (recording) LED light
turns green. This indicates that a file has opened and data
collection has started. The REC LED blinks each time data
is saved to the internal memory.

Surveying with the Receiver

Your receiver can be used to perform the following types of
surveying:

• Static

• Kinematic

• Real-time kinematic (RTK)

Static Survey

Static surveying is the classic survey method, well suited for all
kinds of baselines (short, medium, long). At least two receiver
antennas, plumbed over survey marks, simultaneously collect
raw data at each end of a baseline during a certain period of
time. These two receivers track four or more common satellites,
have a common data logging rate (5–30 seconds), and the same
elevation mask angles. The length of the observation sessions
can vary from a few minutes to several hours. The optimal
observation session length depends on the surveyor’s
experience as well as the following factors:

• The length of the baseline measured

• The number of satellites in view

P/N 7010-0557 www.topconpositioning.com

3-5

Setup and Survey

• The satellite geometry (DOP)

• The antenna’s location

• The ionospheric activity level

• The types of receivers used

• The accuracy requirements

• The necessity of resolving carrier phase ambiguities

Generally , single-frequency receivers are used for baselines
whose lengths do not exceed 15 kilometers (9.32 miles). For
baselines of 15 kilometers or greater, use dual-frequency
receivers.

Dual-frequency receivers have two major benefits. First, dual­frequency receivers can estimate and remove almost all
ionospheric effect from the code and carrier phase
measurements, providing much greater accuracy than single­frequency receivers over long baselines or during ionospheric
storms. Secondly, dual-frequency receivers need far less
observation time to reach the desired accuracy requirement.

3-6

After the survey completes, data the receivers collect can be
downloaded onto a computer and processed using post­processing software (for example, Topcon Tools).

The procedure that follows describes the steps the operator
should take to perform a Static Survey using MINTER.

1. Connect your receiver and computer. See “Connecting the

Kinematic (Stop and Go) Survey

In a kinematic, stop and go, survey, the stationary receiver
(Base station) is set up over a point, such as a survey
monument. The receiver continually tracks the satellites and
logs the raw data into its memory. The rover receiver is set up
over a point and collects data in static mode for 2 to 10 minutes.
When finished, assign the Rover to kinematic status and move
to the next survey point. At this point, and each subsequent
point, the receiver is changed to static mode to collect data. So,
while moving, the Rover is in kinematic mode, and while
collecting data, the Rover is in static mode.

Remember, both Base and Rover receivers must collect
data from the same satellites, at the same data recording
rate, and with identical elevation mask angles.

3. Set up the Rover at an unknown point and press power.
Allow the Rover to collect static data for two to ten
minutes. The REC LED will be orange.

4. Check the STAT light for satellites tracked.

TIP

TIP

Remember, if the REC LED blinks green, the current
mode is dynamic, if it blinks orange, the current mode is
static.

6. Move the Rover to the next location (survey point), and

press the FN key for less than a second to collect the data in
static mode for two to ten minutes.

7. Repeat steps five and six until all points have been
surveyed. The occupation time for the points depends on
the same factors as for the static survey method.

8. When finished, press the FN key for one to five seconds to
stop logging data. Turn off the Rover if needed.

This method of GPS survey allows the operator to reduce the
point occupation time, thus permitting field crews to surve y
many more points compared to the other methods available.

–Extrapolation is for low-latency, high frequency
output (>= 5 Hz) RTK applications. The rover will
extrapolate the base station’s carrier phase
measurement corrections when computing the rover's
current RTK position.

–Delay is for 1 Hz high precision RTK applications.
The Rover RTK engine will compute either a delayed
RTK position (for the epoch to which the newly
received RTCM/CMR message corresponds) or the
current stand-alone position (while waiting for new
RTCM/CMR messages coming from the base).

• Select the antenna status during RTK, either Static or
Kinematic.

• Specify the Ambiguity fixing level (not applicable to

RTK Float). The Ambiguity Fixing Level radio buttons
govern the process of the RTK engine, fixing integer
ambiguities. The RTK engine uses the ambiguity fix
indicator when making decisions whether or not to fix
ambiguities. Low , Medium, and High correspond to the
indicator's 95%, 99.5% and 99.9% states, respectively.
The higher the specified confidence level, the longer

The geodetic coordinates displayed on the Geo tab are
always computed in WGS84 and have four solution types.

• Standalone – where receiver computes 3D coordinates

in autonomous mode without using differential
corrections.

• Code differential – where the Rover receiver computes

the current relative coordinate in differential mode
using only pseudo ranges.

• RTK float – where the Rover receiver computes the

current relative coordinates in differential mode using
both pseudo ranges and phases; however, with a float
solution, the phase ambiguity is not a fixed integer
number and the “float” estimate is used instead.

• RTK fixed – where the Rover receiver computes

current relative coordinates, with ambiguity fixing, in
differential mode.

The LQ field reflects the status of the received differential
messages and contains the following information:

• Data link quality in percentage

• Time (in seconds) elapsed since the last received

message

• Total number of received correct messages (dependent

on the message type received)

• Total number of received corrupt messages (dependent

on the message type received)

If the receiver is not (for some reason) receiving dif ferential
corrections, or if none of the ports has been configured to
receive differential corrections, the LQ field will either be
empty or it will look like this: 100%(999,0000,0000).
