RTK high-precision positioning module

Product Introduction：

GNSS high-precision positioning refers to the positioning accuracy that ordinary civilian positioning codes cannot achieve, generally less than 1 meter accuracy, including sub meter level accuracy, decimeter level accuracy, and centimeter level accuracy. Millimeter level accuracy. At present, there are four ways to achieve high-precision civilian GNSS:

Differential GPS technology. Abbreviated as DGPS. RT;

Satellite based assistive technology, abbreviated as SBAS;  

Single point precision positioning technology, abbreviated as PPP;

Dynamic real-time differential positioning, abbreviated as RTK;

Zhongke Micro Beidou positioning chip, module. The entire line supports the RTCM3.2 protocol, achieving widespread support for DGPS (RTD). The customer is based on the Beidou ground-based augmentation system and the coastal base station broadcasting system. FM radio system. The Internet system, digital radio and other background support can achieve the positioning accuracy of about 1 meter and improve the positioning accuracy.

Zhongke Microelectronics will also gradually launch products that support SBAS functionality. Products that support PPP function and RTK function, to achieve the improvement of high-precision products and assist in the infrastructure construction of Beidou ground-based enhancement system and Beidou satellite based enhancement system.
