In October, we took the SatLab SLC GNSS Receiver to a forest area in Poland to test the SLC’s performance under a tree canopy.
The SATLAB Toolbox application is used for the one-time configuration of the SatLab SLC receiver to download RTK/RTN corrections.
- Bluetooth connection
- Configuration of the modem
- Configuration of NTRIP network access
- Sending NMEA to an external device via Bluetooth port
Power GPS – Application for Android
The test was conducted using the Power GPS application. The Power GPS configuration is only required to connect the application to the SatLab SLC via Bluetooth. Three points were measured to compare the performance of the receiver with an internal antenna and with an external antenna. The table of deviations is shown below.
Compared with the state surveying warp, the differences are about 1-2cm when measuring with and without an external antenna.
Tests in forest area
In the forest, the receiver only works with an additional external antenna, and the position accuracy is 2cm. When moving with the receiver, the accuracy is about 15-20cm. It is necessary to stop for a few seconds to obtain an accuracy of 2cm again. Screenshots from the application and photos from the measurement site are shown below.
The SatLab SLC works very well. It searches satellites quickly and can track 18-20 satellites in the open air. In open areas, it can provide good accuracy and quick initialization and a stable connection with an external or internal antenna. The external antenna amplifies the signal, and there is a visible difference between measurements with and without the antenna near buildings and in the forest.
Simple Operation and Configuration
You only need to configure the SatLab SLC Toolbox once and it will remember all the settings. Therefore, from the second time on, all you need to do is switch it on and connect to a measuring application on your tablet or smartphone.
