1 Overview
1.1 Product Configuration
GR-9029 includes a disk body and a control cable.
The control cable is by default 70cm long. The cable length is customizable with
MOQ.
The button is used to control power ON/OFF and position tagging.
The USB type C connector is used for charging.
1.2 Fixing Screw Holes
At the bottom of the GR-9029 disk, there are four screw holes of M3x8 (mm). These
four screw holes are located at the four corners of a rectangle with edge length of 60
mm as shown below.

GR-9029 User’s Quick Guide

One can attach a tripod, a selfie stick, or anything else via these 4 screw holes with
screws of size M3x8.
For example, one option of pedestal with four magnets at the feet is attached to the
disk with 4 M3x8 screws as shown above.
Another example shown below is to attach a selfie stick to the disk via a metal plate.
1.3 Power ON/OFF
At the end of the cable, there is a button for power control and position tagging.
When power is OFF, touch the button, LED blinks to indicate power ON.

GR-9029 User’s Quick Guide

When power is ON, a button press would tag the current position for reference.
Hold the button (for about 3 seconds), LED would be OFF to indicate power OFF.
In case of BLE connection loss for 3 minutes, it would power OFF automatically to
save power.
1.4 RTCM
Applications running on devices like smartphones, tablets, notebooks etc. could
communicate with GR-9029 via BLE/RTCM to get the RTK precise positions which
could be used for precise navigation, measurement, data logging etc. The RTCM data
is typically encapsulated in NTRIP.
In following description, we take an example of NTRIP application running on an iPad
Pro.
iPad Pro
The iPad should have the internet connection to receive the RTK correction
data from a base or caster. Before having the correction data, one needs to
setup the caster information on the iPad. Please see next section for an
example.
iPad sends the RTK correction data continuously to GR-9029 via a BLE
connection.
iPad receives the RTK calibrated position data from GR-9029 via a BLE
connection. The NMEAdata is by default 1Hz in GGAsentence.

2 BluetoothLE RTK APP
2.1 Where is the APP
An iOS-based APP (BluetoothLE RTK) is prepared for the evaluation of GR-9029.
One can download to test it from the App Store as shown below. That is to say, this
APP could be used on iPad, iMac, or iPhone. You are welcome to give us suggestions
on this APP. APP customization is welcome to meet your specific demand. We hope
that it could be helpful to your business.
2.2 Major Functions
Three rectangles were marked below for description of different functions.

GR-9029 User’s Quick Guide

The green rectangle is for the major menu including four functions.
Setting for NTRIP caster etc.
Clear: to clear the path on the map
Log: to start or stop the logging
File: the logged files were stored here.

2. Red rectangle: Toggle the switch to connect or disconnect the BLE of GR-9029.
3. Blue rectangle is for the connection status (NTRIP & BLE), battery level (GR-
9029), firmware version (GR-9029), and GPS (GR-9029) fix information etc.
In addition, there are three colors associated with the human icon on the map to
indicate different GPS fix status.
Red: normal GPS fix, no RTCM data for RTK fix, in meter-level accuracy
Blue: RTK Float, receiving RTCM data, not yet RTK fix or RTK fix just lost
Green: RTK fixed, in cm-level accuracy
2.3 Settings
Click the Setting function in green rectangle described above, one would be able to
configure NTRIP/Bluetooth LE/Map settings and will see window below.
NTRIP setting
Requires the host address, port number, authentication (user, password)
information for accessing the caster/private base.
To provide the nearest RTK correction data (i.e. shortest baseline), the caster
may require the GGAfor the position of the RTK device. In this case, turn on
this function and the APP will send the location of the iPad to the caster
continuously and automatically. To keep reasonable baseline, iPad should
not be far from the GR-9029.
Bluetooth setting
Name gives the Bluetooth name of the discovered GR-9029. Please click the
SCAN function to discover all Bluetooth devices in the neighborhood. The
default name of GR-9029 is started with “NPASP-“.
In case of multiple GR-9029s are active. One can distinguish one from
another by this name. This name is labelled on the disk body of GR-9029.
Map setting
Allows one to manage path display, measure distance, and use one’s own
map for display. For the details, please see next section.

Editing in this window is not effective before Update. Please remember to click the
Update icon on the upper right corner to enable the changings made on Setting.
2.4 Map Setting
There are three sub-functions under this item.
1. Show Full Path
GR-9029 sends out its position data second by second. However, the APP by default

GR-9029 User’s Quick Guide
8
only displays the position that is tagged with “$KEYPRESSED” in the line following it.
The tag means the user has pressed the button on the extended control cable of GR-
9029.
For example, following two lines were received by the APP. However, only the second
line data is displayed because of the $KEYPRESSED line following it.
$GNGGA,031410.10,2446.41394,N,12100.43552,E,4,12,0.64,122.2,M,16.3,M,1.1,1068*6E
$GNGGA,031411.10,2446.41394,N,12100.43552,E,4,12,0.64,122.2,M,16.3,M,1.1,1068*6F
$KEYPRESSED
If one wants to display all the received data without pressing the button on the
extended control cable, one needs to enable the Show Full Path option.
For example, after this option is enabled, the tester walked a rectangle and had the
path as shown below.

2. Draw Distance
There could be multiple points shown on the map. This function allows one to
measure the distance between any two points. Following picture is an example.

3. Use WMTS (Web Map Tile Service)
In addition to the default map, one can add one’s own map by the WMTS service
function.
Just key in the WMTS URL for the new map is ok. The default one is Apple

GR-9029 User’s Quick Guide

map. The one shown in the screenshot above is for an Open Street Map.
For example, if you have a pipeline map, and you want to find the specific
location of a pipe, this would be a very useful function.
2.5 File Logging
As the log function is enabled and then stopped, a new file is stored in the menu File.
Click on it, one would see all the logged files.
The logged files store positions in NMEA GGA sentence. Here is an example.
