SL900 GNSS RTK System
Note: When the storage space of the receiver is less than 2MB, the red signal lamp will flash quickly and
stop recording. Meanwhile, the existing data files will not be overwritten.
The SL900 receiver file management uses U-Disk storage, plug-and-play, and direct drag-and-drop downloading.
You do not need to download the management software. The SL900 receiver can only download static data by
using the U-Disk mode. It cannot write to the SL900 receiver.
Users can download data through the U-Disk. Use the Mini USB cable when downloading. Connect the receiver
with the computer by using the Mini USB data cable. After the connection, a static drive will appear on the
computer. You can then copy the collected static files by opening the disk.
After downloading, edit the point name and antenna height:

2. The Document Edit dialog box will pop up. Edit the point name and input the antenna height, then click OK.
Note: Static files in the removable disks cannot be deleted directly. You can use the controller software to
do this.
Firmware Upgrade
The receiver uses a 3G network, and the host firmware can be automatically upgraded through the network

The two steps to upgrading the firmware by USB cable are：

you click on the computer.

Set both the base station and receiver position, and then set the Datalink and Other.
1. Select the antenna type and enter both the height and the type.
2. Set the base location.
- If the base station is located at a known point and you know the conversion parameters, do not select the
Average. Directly input or select the point of the WGS-84 BLH coordinates from the point library or open the
conversion parameters in advance and enter the local NEZ coordinates, so that the base station uses the point of
the WGS-84 BLH coordinates as a reference and transmits the differential data.
- If the base station is located at an unknown point, click Average , and click OK after the average to complete
the coordinates of the base station.

Radio mode is the traditional data link mode. The Internal UHF mode is taken as an example to show how the
radio station mode can be introduced by taking simple steps.
- Internal UHF: built-in radio
- Channel: 0 ~ 115, any number, but the rover settings should be consistent with the base station
