1. Introduction
This chapter mainly introduces the overview, system structure, package list,
and installation guide of the Tersus GeoBee30 which is an upgraded version of
Tersus GeoBee.
1.1 Overview
The Tersus GeoBee30 is a dedicated and cost-effective solution to establish a
permanent reference station. With Tersus Ntrip Caster Service, Ntrip Modem
and David30 Receiver, the GeoBee30 opens the possibility for users to
transmit Real Time Kinematic (RTK) corrections via Internet (Ethernet or
2G/3G/4G) in a simple, user-friendly way, just using a SIM card or Ethernet
cable without any need of a static IP. GeoBee30 can also work as GNSS
Rover to receive RTK corrections from Tersus Ntrip Caster or any CORS
service.
Ntrip server mode: use David30 GNSS receiver to create a base station. This
temporary base or CORS are for surveying, agriculture, UAV, machine control,
and etc. It is also ideal for deformation monitoring. Tersus GNSS Inc. provides
Ntrip Caster to transfer data.
Ntrip client mode: connect David30 or other Tersus GNSS receivers to Tersus
Ntrip Caster or any Ntrip/CORS service. David30 is mainly used for surveying,
and also used as a GNSS sensor in various applications, such as mobile
mapping, UAV, machine control, agriculture, and etc.

Note:
1) There are two configuration modes for GeoBee30. GeoBee30 system is zero configuration
if customer adopts GeoCaster provided by Tersus GNSS Inc., as GeoBee30 is
pre-configured when shipped out of factory. GeoBee30 system needs to be configured if
customers demand to set up caster by themselves.
2) David30 GNSS receiver uploads RTCM stream to the NTRIP caster using Ethernet (default) or
Wi-Fi or 2G/3G/4G sorted by priority.
a. When using Ethernet to configure TR600, use Ethernet cable to connect the LAN2 port of
TR600 to your computer, connect LAN1/WAN port to a router to access internet. Make
sure the IP address of your computer is set as “Obtain an IP address automatically”. Type
192.168.100.1 in your browser, use username “root” and “1234” to enter web config page,
make sure the DHCP is on in LAN setting so that TR600 can automatically obtain an IP
address.
b. When using Wi-Fi to configure TR600, search SSID “TR-600” on your computer and
connect it use password 12345678. Type 192.168.100.1 in the browser of your
computer or mobile phone or tablet, use username “root” and “1234” to enter web
config page.
Please note, both Wi-Fi client and Wi-Fi hotspot of Ntrip Modem TR600 are
supported, however they cannot be enabled simultaneously. Wi-Fi hotspot
function is to share internet connection to other devices or configure TR600 via Wi-Fi.
Wi-Fi client function is to use Wi-Fi connection to communicate with caster when
Ethernet connection is not available.
When using Wi-Fi to communicate with caster, choose Wi-Fi Client to access internet
in Network Settings of TR600. Select a SSID to be used and type the Wi-Fi password
in the PSK pin area, click [Save] to save this setting.

Figure 1.2 Wi-Fi client setting
c. When using 2G/3G/4G network for data transmission, GeoBee30 will consume no
more than 3GB mobile data per month. Please contact with your local mobile carrier if
there is any restrictions on wap or data usage.
3) Place the antenna (AX4E02 in the Figure 1.1) in the outdoor open environment. Install
Wi-Fi antenna when Wi-Fi connection is for data communication, and set TR600 as Wi-Fi
client. Install 4G antenna when 2G/3G/4G SIM card is used for data communication.
4) GeoBee30 starts to work in auto start mode by default once it is powered up. According to
the autonomous positioning (without RTK or DGPS), it smoothes out the average value to
be the base coordinate. GeoBee30 outputs the RTCM32 corrections data and sends to the
Ntrip server through LAN, WIFI or 2G/3G/4G mobile network.
5) For the known phase center coordinates of the AX4E02 antenna, the two configuration
methods are as follows:
a. Use the COMM1-Bluetooth module in the package, unplug the COMM1 cable and
insert the Bluetooth module to the COMM1 port of David30 GNSS receiver. Launch
Nuwa app on an android device, connect David30 by paring Bluetooth. Create a base
configuration with manual start in radio mode1, fill in the base coordinates, antenna
height and Ntrip network information. Detailed operation refers to User Manual for

User Manual for Tersus GeoBee30 v1.0

David30 GNSS Receiver. After completing the configuration, disconnect the Bluetooth
connection, disconnect the Bluetooth module and connect back the COMM1 cable.
Figure 1.3 Configure David30 using Nuwa app
Note1: Use Radio Mode in Nuwa when configuring GeoBee30. Because the external
radio and TR600 are both external data link, the principal is the same (log the data
from David30 to external data link).
b. Use the ‘DB9 Female to USB Type A Male converter cable’ to connect the COMM1
cable in Figure 1.1 and a computer, open Tersus GNSS Center application on the
computer, and type below commands in the command window:
UNLOGALL //remove all logs
UNDULATION USER 0.0 //Set user specified undulation value for ellipsoid height2
FIX POSITION B L H //B: latitude (degree), L: longitude (degree), H: height (m)
For example: FIX POSITION 31.24523012 121.58922341 40.35
or POSAVE ON 0.02 //Turn on position average for 0.02 hour (72s)
LOG COM2 RTCM1006 ONTIME 10 //output the base coordinate
LOG COM2 RTCM1074 ONTIME 1 //output GPS observations
LOG COM2 RTCM1084 ONTIME 1 //output GLONASS observations
LOG COM2 RTCM1094 ONTIME 1 //output Galileo observations
LOG COM2 RTCM1114 ONTIME 1 //output QZSS observations
LOG COM2 RTCM1124 ONTIME 1 //output BeiDou observations
LOG COM2 RTCM1230 ONTIME 10 //output GLONASS bias information
LOG COM2 RTCM1033 ONTIME 10 //output antenna, receiver information
(Below commands output ephemerides, not default configuration)
LOG COM2 RTCM1019 ONTIME 5 //GPS ephemerides
LOG COM2 RTCM1020 ONTIME 5 //GLONASS ephemerides
LOG COM2 RTCM1042 ONTIME 5 //BeiDou ephemerides
LOG COM2 RTCM1044 ONTIME 5 //QZSS ephemerides

User Manual for Tersus GeoBee30 v1.0

LOG COM2 RTCM1046 ONTIME 5 //Galileo ephemerides
SAVECONFIG //save configuration
Note2: If customer needs to use global geoidal height model EGM96 for mean sea
level height, type below command to replace the undulation command above.
UNDULATION EGM96 //Set EGM96 geoidal height model
More details about logs and commands refer to BX40C log & Command
document.
Power cycle the receiver or input RESET command to make the above configuration
effective.
6) The known phase center coordinates of the AX4E02 antenna can be obtained from
surveying and mapping department of local government, or calculated from commercial
software such as Bernese or Gamit.
7) If customer needs GeoBee30 work with local CORS system, calculate the accurate
coordinate of the base station under the local CORS framework and configure the base
station with this accurate coordinate. The calculation to obtain this accurate coordinate can
be PPP method and coordinate conversion via point correction using Nuwa app. You can
contact Tersus technical support for detailed method.
