Applications of GNSS in surveying and mapping demand high on accuracy. The GNSS receiver module on the market reaches a static accuracy up to ±(2.5+ 0.5×10-6×D) mm horizontally and ±(5+0.5×10-6×D) mm vertically; its RTK performance reaches up to ±(8+1×10-6×D) mm horizontally and ± (15+1×10-6×D) mm vertically. The GNSS receiver for surveying and mapping applications is also required to be stable and reliable, so the GNSS OEM board and the core component of the GNSS receiver shall meet the demand of high precision and high reliability.
Surveying GNSS applications
