G-mouse tower two-wheel high-precision shared travel solution

The "last mile" of public transportation is the main obstacle for urban residents to use public transportation, and it is also the main challenge faced in the process of building green cities and low-carbon cities.

Shared bicycle (bicycle) companies complete the last "puzzle" of the transportation industry by providing services in campuses, subway stations, bus stops, residential areas, commercial areas, public service areas, etc., and drive residents' enthusiasm for using other public transportation. Synergy with other public transportation modes. Shared bicycles are a time-sharing rental model and a new type of green and environmentally friendly sharing economy. China Tower shared electric motorcycles are another major shared electric motorcycle giant after Meituan, Hello, and Didi. It adopts a dual-frequency RTK high-precision positioning return solution model, making management more convenient. Our company cooperated with China Tower to develop high-precision positioning RTK G-mouse products.

High-precision positioning RTK G-mouse

The concurrent receiving module with built-in multi-positioning system supports GPS, GLONASS, Galileo, Beidou and QZSS L1&L5 band synchronous reception. It has 75 tracking channels and 135 acquisition channels, enabling it to capture and track any multi-satellite mixed signals; compared with a single GPS system, the multi-positioning system has a significantly increased number of visible satellites, greatly reducing the first positioning time, and can achieve stable, higher positioning accuracy and precision even when driving in complex urban environments.
