With its small size, light weight, fast positioning, and stable connection. It is suitable for FPV, RC airplane, quadcopter and others to enhance the users flight experience. Featuring the M10 platform UBX-M10050 GNSS chipset and BUILT-IN QMC5883 , the module offers stronger performance and more accurate positioning. The ultra-thin ceramic antenna uses a special spray painting process to prevent oxidation and scratching, ensuring consistent positioning performance. The built-in battery can realize hot start and realize positioning quickly. It offers six positioning modes, providing more flexible combinations (default GPS + GLONASS + BDS multi-mode positioning).The measured maximum number of search stars can cover 32pcs.
