The BDS-3 navigation satellites system has been completed for one year. Now SOUTH has released new GNSS products to fully support BDS-3 constellation, here are some improvements on the new products:

Tracking more satellites

We tested the new SoC GNSS board receiver in Guangzhou, China. The receiver tracks more than 50 satellites: 9 GPS, 7 GLONASS, 6 GALILEO, 3 QZSS and 25 BDS (12 of them are BDS-2, 13 of them are BDS-3). More satellites in the sky will make GNSS receivers get signals easier and faster. SOUTH new SoC GNSS board has fully supported BDS-3 satellites, so the receiver performance in the field has been greatly improved.

Supporting the new signal band of BDS-3

The BDS-3 constellation has three open service signals: B1C, B2a and B2b (B2b signal provides the PPP service), SOUTH SoC GNSS board receivers can track and use all of them at the same time. The above picture shows the N/E/H errors on different testing: the errors declined with more BDS-3 satellites being used.


Integrated with the SoC gnss board and low-profile antenna, SOUTH new gnss receivers even can track and use QZSS to improve the accuracy, so you may find that the receiver Fixed with QZSS+GPS+GLONASS+GALILEO+BDS.

Getting Fix faster and stably

To transfer the massive differential data flow caused by more and more satellites in the sky, the exclusive “Farlink” protocol on SOUTH new internal radio module has a larger bandwidth, to make GNSS receivers get fix faster and stably. Normally, in urban area,  the new radio can transfer 2-5km at power 1W, in suburban district the distance could reach 8km.
