Inserted with high-sensitive E-bubble and brand-new tilt survey algorithm. GX900 is calibration-free. Immune to magnetic disturbance and free from limitation of tilt angles. GX900 can measure points where a vertical placement of the pole is not possible such as house corner.
Blink when normally receive satellites signals. The times it Satellites Indicator blinks, the number of satellite it tracks. Light without blinking indicates GX900 gets fixed solution Blink regularly with green color means correction data is Datalink Indicator transmitting or receiving normally; blink regularly with blue...
2.2.2 Self check GX900 has self-checking function when you find some malfunctions like the indicators are abnormal or receiver can’t work normally or the device cannot connect via Bluetooth or Wi-Fi, radio mode is not workable or can’t connect to CORS.

4 Setting Up 4.1 Setting Up Base Station 4.1.1 Choose a suitable place A suitable place is essential for base station to better receive the satellites and transmit the UHF signals. A suitable position should comply with following conditions: (1) Choose a wide open area in order to easy and better receive signal of satellites. Besides, make sure there is no covering like roof or heavy foliage.

Figure 4-1 b. Turn the leveling screw C to move the bubble to the center of the circular vial. Figure 4-2 (4) Precisely leveling by using the plate vial a. Rotate the instrument horizontally by loosening the horizontal clamp screw and place the plate vial parallel to the line connecting leveling screw A and B, and then bring the bubble to the center of the plate vial by turning the leveling screws A and B.
4.1.3 Measure antenna height The antenna height must be measured when we use GX900 to collect static data or use it as base station. It’s the “a” show in below Figure 4-5, the height from ground measured point to phase center, only get this height can we know coordinate of the ground measured point.
Wi-Fi or Bluetooth as you prefer. (1) Via Wi-Fi GX900 can be used as a hotspot, use controller to search the Wi-Fi signal of GX900, the Serial NO. of GX900 will show on controller, then select it to finish connect.
2 points. Static surveying provides the highest accuracy achievable and requires the longest observation times, from less than an hour to five hours or longer. The static surveying function in GX900 including outdoor surveying and indoor data post processing.
(c) point and side connecting. Because every type of network has its own advantage and disadvantage, we can combine these types to achieve higher efficient ACNOVO but lower investment in time. Mixed connecting network is common in surveying work.
5 WEB UI Control 5.1 Connect and register WEB UI GX900 can work as Wi-Fi Hotspot. You can connect it with phone, controller, PC or other devices through its Wi-Fi. The default Wi-Fi name is device number, no password needed.
After connecting the Wi-Fi, input IP”192.168.10.1” into your web browser to turn it It will pop up a window like Figure 5-1, requests User name and password, default is as follow: User name: admin Password: password Figure 5-1 The WEB UI includes Status, Position, Settings, Download and Management. 5.2 Status In status, you can see current work status of receiver and some basic information.
Figure 5-2 5.2.2 Data link In “Data link” you can set the channel, frequency and protocol. And you can also do channel detection in this menu. Below pic shows internal radio data link. Figure 5-3...
5.2.3 Satellites In “Satellites” you can set the cutoff angle and can see satellites conditions. Figure 5-4 5.2.4 Information In “Information”, you are able to check information details about this receiver, such as firmware version of the receiver, GPS firmware version, UHF mode information, Network information etc.
Bluetooth. If you choose UHF datalink, you can choose record raw data or not. Select the radio channel and radio protocol as you prefer. GX900 is compatible with various protocols, such as: SATEL, PCC-GMSK, TrimTalk 450S, South 9600, TrimMark III(19200),...

Base mode also contains different datalink; most parameters are same as rover. Just base has more options that can be edited. Figure 5-11 Base mode If use External, you can connect GX900 with external radio via Bluetooth. Besides, GX900 can also connect with other devices via Bluetooth.
5.3.2 Satellites setting In satellites setting, you can set the cutoff angle and select the satellites. Figure 5-12 5.3.3 Device configuration Device configuration can help you set many configurations. Such as select time zone, first storage position etc. Figure 5-13...
5.3.4 NMEA message You can set the NMEA message, turn them on/off. You can also select the frequency here. NMEA includes GGA, GSA, GST, RMC, ZDA, GSV, VTG, GLL, GEDOP, GEREF, GESNR. Below pic shows the general settings. Figure 5-14 5.3.5 View logs and configuration set In “View logs”, you can see previous malfunction record and see previous result of self-checking.
In “Configuration Set”, you can save current configuration you set and you can also use previous setting directly if you had saved. Figure 5-16 5.4 Download data There are 2 kinds of data you can download--static data and backup data. For static data, you can convert it to RINEX.
