Introduce
The PM4 is a small OEM surface mount GPS/GLONASS module that has been specifically designed for use in survey applications. Create more advanced applications and sophisticated configurations with the PM4 OEM Board's higher update rates, noise-reduced raw measurements, additional memory, and higher processor capability. The 66-channel, L1 DGPS and 33-channel,L1 GLONASS board features SBAS support, making it easy to get an accurate signal, anytime, anywhere. Accuracy and stability are excellent due to PM4 Receiver Technology’s more accurate code phase measurements, multipath mitigation improvements, and fewer discrete receiver components.
