GNSS
Region: Global,

G021D is a high-performance and dual-band GNSS module that support all global GNSS constellations: GPS, GLONASS、BDS、Galileo and QZSS. Compared with GPS-only receiver, them module enables multiple GNSS systems that enhances positioning performance.

The module supports AGNSS features to improve the accuracy of positioning, allowing  high-sensitivity and high-precision positioning even in the poor signal environment, as well as fast signal tracking and acquisition. The offline ephemeris feature can extend the operating time to up to 6 days. Moreover, G021D supports antenna detection feature which is able to implement the detection of Open/Short circuit.

G021D integrates efficient power management architecture, while providing high-precision, high-sensitivity and low-power GNSS solution, which make it suitable for high precision industries, like precision agriculture, surveying and mapping, deformation monitoring, Unmanned Aerial Vehicle(UAV), etc..
