Description and Operation

Introduction

DELTA-3N is a powerful and reliable receiver for

high-precision navigation systems, including high dy-

namics systems, for machine and trafc control, as well

as for high-precision surveying and geodynamics and
aerogeophysics applications.

864 GNSS channels of this receiver allow tracking
all current and future satellite signals. DELTA-3N is the
only receiver in the market that can track and decode
the QZSS LEX signal messages.

DELTA-3N can operate as a receiver for post-pro­cessing, as a Continuously Operating Reference
Station (CORS) or portable base station for Real-time
Kinematic (RTK) applications, and as a scientic sta­tion collecting information for special studies, such as
ionosphere monitoring and the like (Fig. 1).

the QZSS (is a proposed three-satellite regional time
transfer system and Satellite Based Augmentation
System for the Global Positioning System, that would
be receivable within Japan), and the Beidou Compass
(Chinese Global Navigation Satellite System), increas­ing the number of satellites your receiver can detect,
thus improving the accuracy of your measuring points,
increasing productivity, and reducing cost.

Several other features provide under-canopy and low
signal strength reception. The DELTA receiver provides
the functionality, accuracy, availability, and integrity
needed for fast and easy data collection.

Measuring with the right GNSS receiver can pro­vide users accurate and precise positioning, a require­ment for any measuring project. This section gives an
overview of existing and proposed Global Navigation
Satellite Systems (GNSS) and receiver functions to
help you understand and apply basic operating princi­ples, allowing you to get the most out of your receiver.

Figure 1. DELTA-3N

DELTA can receive and processes multiple signal
types improving the accuracy and reliability of your
measuring points and positions, especially under dif­cult jobsite conditions.

The GNSS component of DELTA receivers means
you can access the GPS (Global Positioning System)
satellites of the United States, the Galileo (an upcoming
global positioning system maintained and operated by
Galileo Industries), the GLONASS (Global Navigation
Satellite System) satellites of the Russian Federation,

to display and control data input and output.

Figure 4. DELTA Ports

• Power – used to connect the receiver to an exter­nal power source. This port can also be used to
charge the batteries.

• Serial – used for communication between the re­ceiver and an external device.

• Ethernet - used to connect the receiver to local
network.

Figure 3. DELTA TriPad

The STAT (status) LED displays the number of

tracked satellites.

• Green – eight and more satellites.

• Yellow – ve to seven satellites.

• Red – less than ve satellites.

• No light – no satellites.

Effective number of satellites are total number of sat­ellites tracked minus the number of non-GPS systems
tracked. E.g. if 8 GPS and 5 GLONASS are tracked the
effective number of satellites is 12.

The REC (record) LED displays the data recording
status and blinks on each recording.

• Green – recording data.

• Yellow – less than 10 min memory left.

• Red – memory is full.

• No light - not active.

The On/Off (power) button turns the receiver on and
off.

The FN button starts/stops data recording.

Data and power ports

• USB –used for high-speed data transfer and com­munication between the receiver and an external
device.

The DELTA-3N receiver can be equipped according
users need and have different connectors on the back
panel. Below are presented some examples of possible

congurations:

• The external GNSS antenna connects to the TNC
external antenna connector (optional)

• The 1PPS and Event marker BNC connectors (up
to two) (optional)

• External Frequency Input/Output BNC connec­tor (optional)

Turning On/Off

To turn ON the receiver, press and hold the power
button until the LEDs briey ash. To turn OFF the re­ceiver, press and hold the power button for more than
one and less than four seconds (until both the SAT and

DELTA-3N saves the last power status and restore it

after voltage loss.

Power supply requirements

The socket-outlet shall be installed near the equip-

ment and shall be easily accessible.

A single external power supply with 5 pin ODU
connector or SAE connector is necessary to operate
DELTA-3N. If external power supply has only SAE
connector, Receiver-to-SAE power cable shall be used.
The external power supply needs to be Listed for US

and Certied for EU countries, it needs also to be a

Limited Power Source and have an output rated for 14.5

- 35 V DC, 2A. This may not be the same range as other
JAVAD GNSS products with which you are familiar.
To avoid the introduction of hazards when operating
and installing, before connecting of the equipment to
the supply, make sure that the supply meets local and
national safety ordinances and matches the equipment’s
voltage and current requirements.

Warning: Never attempt any maintenance or cleaning of the

supply while plugged in. Always remove supply from AC power
before attempting service or cleaning.

Cables

The DELTA-3N receiver package includes standard

communication and power cables for conguring the

receiver and providing a power source to the receiver.

• Receiver-to-computer RS232 serial cable – con­nects the receiver’s serial port and an external device
(hand-held controller or computer) p/n 14-578103­01

• Receiver-to-SAE power cable – connects the re­ceiver’s power port and the power supply’s SAE
connector or the extension cable’s SAE connector
p/n 14-578101-01

• SAE-to-SAE cable extension – connects SAE con­nectors over longer distances p/n 14-578102-01

If the voltage supplied is below the minimum speci-

cation, the receiver will suspend operation. If the volt­age supplied is above the maximum specication, the

receiver may be permanently damaged, voiding your
warranty.

Make sure cords are located so that will not be stepped
on, tripped over, or otherwise subjected to damage or
stress. Do not operate equipment with a damaged cord
or plug – replace immediately. To reduce the risk of
damage to the equipment, pull by the plug body rather
than the output cord when disconnecting the equipment.

Warning: Do not operate the supply if it has received a sharp

blow, been dropped, or otherwise damaged. Do not disassemble
the supply.

Before connecting the external power source and the
receiver, make sure that the power source matches the
receiver’s voltage and current requirements.

Powering the receiver

Option Authorization File (OAF)

JAVAD GNSS issues an Option Authorization File

(OAF) to enable the specic options that customers

purchase. An Option Authorization File allows custom­ers to customize and congure the DELTA-3N receiv­er according to particular needs, thus only purchasing
those options needed.

Typically, all DELTA-3N receivers ship with a tem­porary OAF that allows the receiver to be used for a
predetermined period of time. When the receiver is
purchased, a new OAF activates desired, purchased op­tions permanently. Receiver options remain intact when
clearing the NVRAM or resetting the receiver.

Managing and Operating
Receiver using NetView

To check the status of the internal batteries, view the
BAT LED or check the status using JAVAD GNSS soft­ware. Check the BAT LED for battery status.

To charge the receiver internal batteries, take the fol­lowing steps:

• Plug the Receiver-to-SAE cable’s connector into
the power port of the receiver (14-578125-01).

• Connect the opposite end of this cable with the
battery charger’-s SAE connector (22-570101-01).

• Plug the other end of this cable into an AC outlet
with cable (14-508053-01). Leave overnight.

Configuring Receiver

Both Base and Rover receivers must be congured

according to the desired survey method.

In applications where real-time positioning results
are required, the Base receiver provides the correction
information needed to properly calculate the location
of the Rover receiver. A Base station is normally set up
over a known point and collects GPS/GLONASS data
from satellites. As the receiver picks up satellite data,
it measures the carrier and code phases to accurate­ly compute and verify its location. Then, the receiver
transmits this information via radio (UHF or GSM) to
the Rover receiver.

Figure 5. NetView: Connection via serial port

Establishing an USB connection

Make sure the computer has JAVAD GNSS’s USB
driver installed (available from www.javad.com) be­fore continuing.

1. Using the USB cable, connect the USB port on the

receiver to a USB port on the computer.

2. Press the power buttons on the receiver and com-

puter to turn them on.

3. Start NetView and select USB as type of connec-

tion mode and select USB port ID from the list

www.javad.com 9

The Rover receiver applies correction information
from the Base station to its current location to accu­rately calculate one or more points. Rovers are mobile
GNSS receivers on a survey pole or bipod that com­pares the information from the Base station to the data
it logs from satellites and applies correction algorithms
to accurately calculate a new point.

In applications intended for post-processing, the re­ceivers typically log code phase and/or carrier phase
measurements separately from common satellites and
during the same time interval. This data is then pro­cessed using post-processing software (for example,
Justin).

When conguring receivers for RTK surveying, use

the following list to ensure the receivers are properly
set up:

Congure one receiver as an RTK Base station and

the other receiver as an RTK Rover.

Congure the communication data link for transmit­ting and receiving corrections.

Set up the Base receiver over a known point to begin
collecting static observation data and transmitting cor-

rections. Set up the Rover receiver to begin collecting
RTK data.

When conguring receivers for post-processing sur­veying, use the following list to ensure the receivers are
properly set up:

Congure one receiver as a Base station and the oth­er receiver as a Rover.

Set up the Base receiver over a known point to begin
collecting static observation data. Set up the Rover re­ceiver to begin collecting static or kinematic observa­tion data.

Note: Do not make other changes without consulting the Net-

View Software Manual.

1. Connect the receiver and computer, start NetView

and establish the connection as described above.

Setup and survey

After conguring the receivers for surveying, each

receiver needs to be setup up and the receiver’s height
measured and the survey can begin. The MinPad pro­vides quick access for logging data, changing receiver
modes, and viewing general data logging and satellite
information during a survey.

A typical GPS survey system consists of a Base sta­tion set up over a known point and a Rover receiver set
up to be a mobile data collector. After setting up the
Base and Rover receivers, the antenna height must be
measured.

Before collecting data, make sure the Base and Rover
receivers contain a current almanac and current ephem­eris data.

The Base station must be set up, logging data, and
transmitting data before setting up the Rover receiver.
Receiver setup for either post-process or RTK surveys
is the same.

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 of-

ten larger in area than can reliably t on a at 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:

• 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.

The point to which surveying with GNSS 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 com-

pensate for this point not being at a physical surface of
the prism. For a GNSS antenna, the offset is entered
depending on the type of measurement taken.

For vertical, the offset is simply added to the mea-

sured vertical height to produce a “true” vertical height.

For slant height, the vertical height must rst be cal­culated using the radius of the antenna, then the offset
can be added.

The offsets are different because of the difference in
location between the slant measuring point and the ver­tical measuring point.

Measure the antenna height above the control point
or marker, either the slant height or the vertical height.

Record the antenna height, point name, and start time

in the eld notes

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

• 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

To start survey DELTA-3N should be set up on a tri­pod or in a pole.

Collecting data

See the remaining sections in this chapter for more
information on collecting data.

• Turn on the receiver.

• Once the receiver has locked on to eight or more
satellites the STAT light will green.

• 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.

• To begin collecting data, press and hold the FN

button (for more than one second and less than ve

seconds).

• Release the FN button when the REC (recording)

LED turns green. This indicates that a le has opened

and data collection has started. The REC LED blinks
each time data is saved to the internal memory.

• When nished, press and hold the FN button until
the REC LED light goes out.

To turn off the receiver, press and hold the power key
until all lights go out, then release.

Static Surveying for Base Stations

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

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 benets.

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

After the survey completes, data the receivers col­lect can be downloaded onto a computer and processed
using post-processing software (for example, JAVAD
GNSS Justin).

Kinematic (Stop & Go) Surveying for Rover
Stations

In a kinematic, stop and go survey, the stationary re­ceiver (Base station) is set up at a known point such as
a survey monument, or an unknown point. The receiver
continually tracks satellites and logs raw data into its
memory. The Rover receiver is set up at an unknown
point and collects data in static mode for 2 to 10 min­utes. When nished, 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.

• Set up the Rover at an unknown point and press
power. Allow the Rover to collect static data for two

14 www.javad.com

to ten minutes. The REC LED will be yellow.

• Check the SAT light for satellites tracked.

• When nished, press the FN button for less than 1
second to assign the Rover to kinematic.

• Move the Rover to the next location (survey point),
and press the FN button for less than a second to col­lect the data in static mode for two to ten minutes.

• Repeat steps ve 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.

• When nished, press the FN button for one to ve
seconds to stop logging data. Turn off the Rover if
needed. This method of GNSS survey allows the
operator to reduce the point occupation time, thus

permitting eld crews to survey many more points

compared to the other methods available.

Real Time Kinematic Surveying

With RTK surveying, as with kinematic surveying
described above, one receiver serves as the reference
station and conducts observations with its antenna af-

xed to a stationary tripod or some other device. The

other receiver functions as a rover and conducts obser-

vations (using an antenna) afxed to a mobile pole and

moved to observation points.

Unlike post-processed kinematic surveys, RTK sur­veys utilize a communications link between the Base
and Rover. Using a radio modem link, the Base receiv­er transmits its measurement and location data to the
Rover receiver. The Rover, based on the transmitted
data and its own observation data, immediately con­ducts a baseline analysis and outputs the results.

Usually, the receiver will start to output the coordi­nates of the antenna’s phase center along with the solu­tion type within 10–30 seconds. However, UHF radios
and GSM phones may take as long as 60 seconds to
synchronize. The geodetic coordinates displayed on the
Location tab are always computed in WGS84 and have
four solution types.

• Standalone – where the 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 oat – where the Rover receiver computes
the current relative coordinates in differential mode
using both pseudo ranges and phases; however, with

a oat solution, the phase ambiguity is not a xed
integer number and the “oat” estimate is used in-

stead.

• RTK xed – where the Rover receiver computes

current relative coordinates, with ambiguity xing,
in differential mode. The LQ eld reects 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 differential corrections, or if none of the ports

has been congured to receive differential correc­tions, the LQ eld will either be empty or it will

look like this: 100%(999,0000,0000).

Receiver and File Maintenance

If post-processing the data after completing a mea­suring, the data in the receiver’s memory will need to
be downloaded to a computer. Downloading and delet-

ing les will also prepare the receiver’s memory for the

next measuring. Occasionally, the receiver’s NVRAM
may need to be cleared to eliminate communication
or tracking problems. As project expectations expand,
the receiver’s OAF may need to be updated to provide
expanded operation and functionality. The receiver

requires rmware to properly operate and provide ap­propriate functionality. As JAVAD GNSS releases rm-

ware updates, loading these updates into the receiver
will ensure that the receiver operates at its full potential.

Deleting Files and Downloading Files to a
Computer

When your measuring nishes, you can down­load your measuring les to a computer for storage,

post-processing, or backup. Also, the DELTA memory

holds a nite amount of les and information, so down­loading the les to a computer ensures that no les are
lost. You should download les as soon as possible af-

ter collecting data at the jobsite. NetView provides a

File Manager to download les to your computer and
delete les from the receiver DELTA.

Navigate to the location of the new Option
Authorization File. OAFs have .jpo extension and are
unique to each receiver.

Clearing the NVRAM

The receiver’s Non-Volatile Random Access Memory
(NVRAM) holds data required for satellite tracking,
such as almanac and ephemeris data, and receiver posi­tion. The NVRAM also keeps the current receiver’s set­tings, such as active antenna input, elevation masks and
recording interval, and information about the receiver’s

internal le system.

Even though clearing the NVRAM is not a com­mon (nor normally a recommended) operation, there
are times when clearing the NVRAM can eliminate
communication or tracking problems. Clearing the
NVRAM in your receiver can be interpreted as a “soft
boot” in your computer. After clearing the NVRAM,
your receiver will require some time to collect new eph­emerides and almanacs (around 15 minutes). Clearing

the NVRAM of your receiver will not delete any les

already recorded in your DELTA’s memory. However,
it will reset your receiver settings to factory default val­ues.

In addition, the NVRAM keeps information about

the receiver le system. Note that after clearing the
NVRAM, the receiver’s SAT LED will ash yellow for

a few seconds indicating that the receiver is scanning

and checking the le system.
