Introduction
- MG-A01(M10 Ultra) GNSS module integrates a special version of the u-blox 10th-generation receiver chip – M10050, which runs at a higher frequency than normal, and the magnetic sensor – QMC5883L. It supports all L1 GNSS signals (GPS/GLONASS/Galieo/BeiDou) and can use up to 32 satellites simultaneously for navigation.
- The high-gain 25 x 25 x 4mm patch antenna provides the best performance.
- Built-in flash: parameters can still be saved when the module loses power.
Why M10 Ultra
As we all know, the M10 is the latest generation of GNSS receiver, with faster startup speed, higher positioning accuracy, and support for more satellites. But at the same time, M10 (5Hz) sacrifices the navigation update rate compared to M8 (10Hz) and M9 (25Hz). In order to solve this problem, we integrated an Ultra version of the M10 chip into MG-A01, which runs at a higher frequency, making it possible to achieve a 10Hz navigation update rate while using 32 satellites.
In order to solve the problem of unstable navigation update rate of M10, the developer team of Ardupilot forcibly limited the number of satellites by turning off BeiDou B1L and GLONASS. In fact, they could choose to use the M10 Ultra without making any changes.
