Broadgnss Technology Intros GPS Receiver With Real-Time Array Calibration Technology

Broadgnss Technology, a supplier of Global Navigation Satellite System (GNSS) receiver solutions, has announced a new high-precision satellite position receiver with patented real-time array calibration (RAC) technology. Broadgnss's RAC receiver is currently used for autonomous vehicles, drones, precision agriculture, robotics and other applications.

The system features positioning accuracy closer than 1 meter, the company reports, by receiving only single-frequency (GPS L1) satellite signals—the RAC technology in high-precision satellite positioning that frees the dependence on traditional augmentation network and reduces costs. This enables high-precision satellite positioning in large-scale applications, the firm explains.

The main problems facing current high-precision GPS systems are high costs and geographical limits, according to the company. High-precision GPS receivers can be costly, and reference stations for RTK networks and communication networks have many blind spots on Earth. In addition, satellite-based PPP receivers have a long initial start time issue. RAC receivers are designed to overcome the barriers of traditional high-accuracy GNSS receivers, the company indicates, at a cost as low as only a tenth of traditional solutions.

"RAC technology is one disruptive, high-precision GPS solution," said Yan Shen, Broadgnss's CEO, in a prepared statement, "as people pursue more accurate GPS location. We think cost shouldn't be the barrier of scaling up; meanwhile, RAC technology opens one door for high-accuracy GPS research, which could be used in more space. Broadgnss is aimed to democratize the high-accuracy GNSS service and will keep moving toward this goal."
