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.<br><br>Chip: M10 (ten generation chip) Frequency: GPS L1,GLONASS L1,BDSB1,GALILEO E1,SBAS L1.QZSS L1 Power: 5V Size: 18mmx18mmx4.6mm Antenna: ceramic antenna (oil spraying process, prevent scratching and oxidation) Receiving channels: 72 search channels Compass: QMC5883 Baud rate: 115200dps Output protocol: NMEA UBLOX (dual protocol) Output frequency: 1Hz-10Hz, Default 10Hz Speed accuracy: 0.05m/s Horizontal positioning accuracy: 2D ACC1.5m(open air) Trace-162dBm Capture -160dBm Altitude: 50000m Speed: 500m/s Acceleration: 4G Operating temperature: -40-+85 Storage temperature: -40-+105 Colour:Photo Color Material:composite materials<br><br>Package Contents: 1 x WS-M181 GPS<br><br>Only the above package content, other products are not included.
