M15 High Precision Board

M15 High Precision Board

Multi-band, multi-constellation satellite receiver, with a variety of data interfaces.

High-precision board. Multi-band, multi-constellation satellite receiver, with a variety of data interfaces.

Product Introduction

The M15 is a new multi-band, multi-constellation satellite receiver with a variety of data interfaces. It is suitable for UAVs, autonomous robots, precision control, unmanned driving, and other fields. It can track all GNSS constellations and current satellite signals, with unique AIM+ anti-interference technology. LOCK+ enables tracking during high vibration and impact; APME+ mitigates multipath to separate direct signals from reflections; IONO+ protects against ionospheric interference, especially in complex environments. The M15 is widely used in the GNSS mass market.
