cable.
2. Configure the data logging settings through a web browser (see 7.4.1.
Log Settings submenu for instruction).
Notes
Select a data logging session, and then select “External Storage” as
the store location.
Make sure the data logging session selected is switched on after the
configuration. Also, user need to verify the Log Status is “Recording”
before leave the web browser.
3. The receiver will log static data to the USB drive.
Note – To download the data logged in the USB driver, connect the USB
driver to the computer, find a folder named as “repo” in the USB drive, and
then locate the logged static data according to procedure illustrated as
follows:

using the web browser (see 7.11.3. Firmware update submenu for
instruction).
2.9. DOWNLOADING LOGGED DATA
Data logging involves the collection of GNSS measurement data over a
period of time at a static point or points, and subsequent postprocessing of
the information to accurately compute baseline information. Data logging
using receivers requires access to suitable GNSS postprocessing software
such as the CHC Geomatics Office (CGO) Software.
The following figure shows how to connect to the computer for downloading
logged data:
Page 28
2. Getting started with i80
i80 GNSS Receiver User Guide Page 26
The procedures of downloading logged data in the receiver are as follows:
1. Switch on the receiver and connect it with a computer by USB Cable.
After the successful connection, a removable disk named as the Serial
Number (SN) of the receiver will appear on the computer.
2. Double click the removable disk and you will see the folder named as
“repo”. Double click this folder, you will see 9 folders. The “push_log”
folder is used to save the log files, and the other 8 folders represent
different logging session and are used for store static data.
3. Double click the folder that you has configured to store the static data,
you will see the folder(s) created by the i80 system automatically and
named by the date which is decide by GPS time when you start to log
data.
4. Select the destination folder and double click it, and then two folders
named as different data format (hcn and rinex) will be displayed.

4. BASE STATION SETUP AND OPERATION
Real-Time Kinematic (RTK) operation provides centimeter-level precision by
eliminating errors that are present in the GNSS system. For all RTK
operations, you require both a rover receiver and a source of corrections
from a base station or network of base stations.
A base station consists of a receiver that is placed at a known point. The
receiver tracks the same satellites that are being tracked by the rover
receiver simultaneously. Errors in the GNSS system are monitored at the
base station, and a series of position corrections are computed. The
messages are sent through a radio link to the rover receiver, where they are
used to correct the real time positions of the rover.
This chapter provides the information to help you identify good setup
locations, outlines basic precautions that you need to take to protect the
equipment, and describes the conventional process to set up the base
station and the configuring procedure that required for transmitting
correction data.
4.1. BASE STATION SETUP GUIDELINES
For good performance, the following base station setup guidelines are
recommended:
Place the GNSS receiver in a location on the worksite where equal
range in all directions provides full coverage of the site.
Place the GNSS antenna in a location that has a clear line of sight to the
sky in all directions. Do not place the antenna near vertical obstructions
such as buildings, deep cuttings, site vehicles, towers, or tree canopy.
The GNSS antenna must have a dear line of sight to the sky at all times
during operation.
Place the GNSS and radio antennas as high as practical. This minimizes
multipath from the surrounding area, and enables the radio to
broadcast to the maximum distance.
Choose the most appropriate radio antenna for the size of the worksite.
The higher the gain on the antenna, the longer the range.
Make sure that the GNSS receiver does not lose power. To operate
continuously for more than a few hours without loss of power at the
base station, provide external power. When you use an external power
supply, the integrated battery provides a backup power supply,
enabling you to maintain continuous operation through a mains power
failure.
Do not locate a GNSS receiver, GNSS antenna, or radio antenna within
400 meters (about 1,300 feet) of transmitters, such as a power radar or
Page 37
4. Base station setup and operation
i80 GNSS Receiver User Guide Page 35
cellular communications tower.
Do not set up the base station close to the sources of electromagnetic
interference, include alternators and generators, electric motors,
equipment with DC-to-AC converters, etc.
Do not operate the receiver outside the specified operating
temperature range -40°C to +60°C (-40°F to +140°F).
Take reasonable care to keep the GNSS receiver equipment dry, which
could prolong their life and reduce the effects of corrosion on ports and
connectors.

The second part of the RTK GNSS system is the rover receiver. The rover
receiver is moved between the points that require measurement or stakeout.
The rover receiver is connected to a base station or to a source of RTK
corrections such as a CORS (Continuous Operational Reference System) or
the CHC APIS service. The connection is provided by:
an integrated radio
an integrated cellular modem
a cellular modem in the controller
This chapter provides the information to help you identify good setup
locations, describes the conventional process to set up the rover station and
the configuring procedure that required for receiving correction data.
5.1. ROVER STATION SETUP GUIDELINES
For good rover operation, observe the following setup guidelines:
Place the GNSS antenna in a location that has a clear line of sight to the
sky in all directions. Do not place the antenna near vertical obstructions
such as buildings, deep cuttings, site vehicles, towers, or tree canopy.
GNSS rovers and the base station receive the same satellite signals
from the same satellites. The system needs five common satellites to
provide RTK positioning.
WARNING – Take care not to touch overhead power lines with the CHC i80
GNSS receiver or the range pole when moving the equipment into position.
Touching overhead power lines may cause electrocution, leading to serious
injury.
GNSS satellites are constantly moving. Because you cannot measure at
a specific location now does not mean that you will not be able to
measure there later, when satellite coverage at the location improves.
To get a fixed position solution with centimeter precision, initialize the
RTK rover receiver. For initialization to take place, the receiver must
track at least five satellites that the base station is also tracking. In a
dual-satellite constellation operation, for example, GPS and GLONASS,
the receiver must track at least six satellites.
Page 45
5. Rover station setup and operation
i80 GNSS Receiver User Guide Page 43
To continue to survey at centimeter precisions, the rover must
continuously track at least four satellites that the base station is also
tracking. The radio link between the base and rover receivers must also
be maintained.
Loss of the satellite signals will result in a loss of centimeter position
precision.

6.3.2. SURVEY WITH TILT SENSOR
The i80 receiver is integrated with tilt sensor, which allows the use of
eBubble (electronic bubble) and tilt compensation. The tilt compensation
allows the collection of points even when the receiver is tilted up to 30
degrees off plumb. When the terrain or structures around the point do not
allow full plumbing of the receiver, the built-in tilt sensor will compensate
Page 61
6. Survey with LandStar 6 software
i80 GNSS Receiver User Guide Page 59
for the tilt of the range pole. The eBubble can be displayed in the lower left
corner of any survey window within the CHC LandStar 6 software.
To bring the eBubble and tilt compensation into full play, it is very important
to ensure the integrated tilt sensor is correctly calibrated. When calibrating
the integrated tilt sensor, users need to make sure that a range pole or a
tripod with tribrach have been well calibrated. The quality of the integrated
tilt sensor calibration is directly related to the quality of the mechanic
bubble and its calibration.
The integrated tilt sensor calibration is performed within the CHC LandStar 6
software. To calibrate the integrated tilt sensor, place the receiver on a
stable range pole or tripod with tribrach. Level the receiver using the
mechanical bubble on the range pole or tribrach.

General speaking, if a three- or seven-parameter datum
transformation has been configured for project, users can skip the
Page 67
6. Survey with LandStar 6 software
i80 GNSS Receiver User Guide Page 65
site calibration and the coordinates measured will be transformed
automatically into local grid coordinates.
If a projection and datum transformation have already been
specified, users can reduce any discrepancies between the WGS-84
coordinates and the local grid coordinates by performing a site
calibration.
To perform the site calibration, users need to measure the control
points with GNSS receiver first.
To perform site calibration:
1. In the main menu, tap Survey → tap Point Adjust.
2. Tap button in the lower left corner to add point pair(s).
3. In the pop-up screen, tap button on the upper side of the screen
to add the existing GNSS point or key in a GNSS point.
4. Tap button on the lower side of the screen to add the existing
known point or key in a known point.
5. Tap button to go down to the bottom of the page.
6. Select the adjustment method from the dropdown list next to Method
field.
Page 68
6. Survey with LandStar 6 software

Note – Users can determine whether this point pair is involved in the
computation of either horizontal or vertical adjustment, or both.
7. Tap button in the lower right corner to save the point pair.
8. Continue the Step 2 to Step 7 to add all the point pairs.
9. If necessary, select the fit method for vertical adjustment from the
dropdown list next to Fit Method field.
Notes
The fit methods of horizontal and vertical adjustment are “TGO”
and “Fixed difference” respectively, by default.
There are four available fit methods for vertical adjustment: Fixed
difference, Plane fitting, Curved surface fitting and TGO.
1. The “Fixed difference” fit method is used when the measuring
surface is almost horizontal, and it requires at least 1 point pair
with elevation information to be involved in the computation.
Page 69
6. Survey with LandStar 6 software
i80 GNSS Receiver User Guide Page 67
2. The “Plane fitting” fit method is used when the measuring
surface is level, and it requires at least 3 point pair with
elevation information to be involved in the computation.
3. The “Curved surface fitting” fit method is used when the
measuring surface is uneven, and it requires at least 6 point
pair with elevation information to be involved in the
computation.
4. The “TGO” fit method is almost the same with “Fixed
difference”, except that this method is more convenient for
computation using computer.
10. Tap button to perform the calibration, and then the “HError” and
“VError” information related to each point pair will be displayed.
Note – For best results, make sure that the control points are evenly
distributed to the extent of the job area.

6.5. BASE SHIFT
Typically, the Real-time kinematic (RTK) operation requires a data link to
send observations or corrections from the base station to the rover, and
then the rover will calculates its position in real time.
Within a project, when the base receiver is restarted or moved, the base
coordinated system will shift each time the position of base station is
changed. Normally, the coordinates determined by the base station that set
up on a control point should be in the same coordinate system. However,
coordinates determined by the base station that set up on an autonomous
point should be carried out a base shift, which provided by CHC LandStar 6
software, to keep their base station coordinate the same as the initial
coordinate system.
Notes – To perform the base shift, make sure that the two base stations have
been linked together by at least one common point that sharing with the
same position, which means that the common point not only has the
coordinate determined by the initial coordinate system, but also own the
coordinate surveyed from another base coordinate system that need to be
shifted.
To perform a base shift:
1. In the main menu, tap Survey → tap Base Shift.
2. Tap button next to the GNSS Point field to select the common
point surveyed from the base coordinate system that need to be
Page 72
6. Survey with LandStar 6 software
i80 GNSS Receiver User Guide Page 70
shifted.
3. Tap button next to the Known Point field to select that common
point determined by the initial coordinate system.
4. The offset information of base coordinate system that need to be
shifted will be displayed automatically.
5. Tap button → a message will pop up asking user whether to
translate the coordinates determined by the current base coordinate
system to the initial one.
6. If tap YES button, all the coordinates determined by the current base
coordinate system will be translated. Also, the Point Data Management
screen will pop up to help user check whether the coordinates
determined by the current base coordinate system have changed.
