G021RD-01

GNSS

Region： Global,

Fibocom G021RD is a dual-band, multi-constellation GNSS module that support all global GNSS constellations: GPS、GLONASS、BDS、Galileo and QZSS. Comparedto only L1 GNSS signals, G021RD could receive and track a higher number of visible satellites in multiple bands, also it integrates efficient power management architecture.

The module supports Real-Time Kinematic (RTK)functions to provide centimeter-level poisoning accuracy. Besides, AGNSS can enhance the sensibility of acquisition inshorter time even under weak signal environment. The offline ephemeris feature can extend the operating time to up to 6 days. Moreover, G021RD supports antenna detection feature which is able to implement the detection of Open/Shortcircuit.

It's an ideal solution for navigation applications on vehicles, consumable electronic devices, and outdoor service robots with the advantages of high precision and high sensitivity.
