Applied BX316R GNSS PPK Receiver for UAVs

HG Robotics Co., Ltd is based in Thailand. With rich experience in artificial intelligence, machine learning, robot localization, navigation, path planning and embedded system design and development, it has gained many awards in terms of small-sized soccer robot, rescue robot as well as autonomous vehicle.

"One of our projects is to integrate new GNSS hardware to our existing unmanned aerial vehicles. To faster lead time to market and improve the performance for UAV application, we have strong need to find a precise portable global positioning device. With BX316R GNSS PPK receivers and the compatible GNSS antennas, they fit well to our existing hardware (UAVs) and work well and robustly." Mr. Sompol Suntharasantic
Engineer of HG Robotics Co., Ltd.

GNSS PPK Receiver test Setup  

In this application, he used BX316R to acquire GNSS data from Tersus AX3702 antenna and custom antenna.
The antenna was connected to BX316R at primary SMA connector and record the data for 10 to 15 minutes. After that, he switched to another antenna and recorded again.
The data was recorded in a raw format by the following command:

LOG RANGEB ONTIME 1
LOG GPSEPHEMB ONTIME 30
LOG BDSEPHEMERISB ONTIME 30
LOG GLOEPHEMERISB ONTIME 30
SAVECONFIG
LOG FILE RANGEB ONTIME 1
LOG FILE GPSEPHEMB ONTIME 30
LOG FILE BDSEPHEMERISB ONTIME 30
LOG FILE GLOEPHEMERISB ONTIME 30
SAVECONFIG

Result

In this application, he used BX316R to acquire GNSS data from Tersus AX3702 antenna and custom antenna. The result showed that BX316R could retrieve GNSS data without any problems even at a high number of satellite present. The number of satellite detected were evaluated similar for both Tersus AX3702 antenna and custom antenna. While AX3702 antenna exhibited a strong GNSS signal strength for both L1 and L2, the custom antenna performed obviously inferior for L2.
