Dual-Resolving RTK Technology test
Embedded with Dual-Resolving RTK technology,observations from primary antenna and secondary antenna are transferred to two processors where RTK are computed independenty, improving system robustness and positioning availability in complex environments.
Full-constellation & Multi-frequency
K827N can track all the current and planned GNSS constellations, including GPS,BDS-2,BDS-3,GLONASS,Galileo, NavIC,QZSS and SBAS.Your GNSS solutions will never be outdated with K827N GNSS boards.
On Board IMU
K827N combines GNSS and IMU to deliver precise positioning in challenging environment,such as urban canyons, under trees or bridges.When losing GNSS signal,it can keep centimeter level positioning in 3s and meter-level in 10s.
Strong Compatibility
Designed with standard I/O and pin definition,the K827N is compatible with mainstream GNSS boards from physical to data format,ensuring a seamlessly replacement for customers who use boards on worldwide standard 20pins to 28pins.
