High-accuracy Satellite Navigation Receiver (ZK-251G)
Product profile and purpose
ZK-251G satellite navigation receiver adopts GPS L1/L2 and GLONASS L1/L2 dual-system four-frequency highly-dynamic solution engine, can achieve centimeter-level positioning accuracy, and support GPS/ GLONASS single-system independent positioning and GPS+GLONASS multi-system combination positioning, and its hardware dimension, interface and data command are compatible with imported panel card. It is superior to the binary-star solution engine of the imported panel card, can truly realize binary-star solution of GPS+GLONASS, and adapt to harsher and more remote positioning environment.
Main characteristics
It is equipped with GPS L1/L2 and GLONASS B1/B2 two-star four-frequency, with either GPS/ GLONASS single-system independent positioning, or GPS+ GLONASS multi-system combination positioning, is compatible with physical dimension, electrical interface and command message of imported panel card, can replace imported card, and can be customized according to special application demands of different industries, with light weight, small volume, and low power consumption.
