The Precision GPS/GNSS Modules (Ai-Thinker GP-02 and u-blox NEO-M8N) are advanced satellite positioning solutions designed to provide accurate location, velocity, and time data for embedded systems.
The Precision GPS/GNSS Modules (Ai-Thinker GP-02 and u-blox NEO-M8N) are advanced satellite positioning solutions designed to provide accurate location, velocity, and time data for embedded systems. Equipped with high-gain ceramic patch antennas, these modules deliver exceptional signal reception and rapid fix times, even in challenging RF environments.
Supporting multi-constellation GNSS reception (including GPS, GLONASS, BeiDou, and Galileo), these modules achieve sub-2.5 meter positioning accuracy with low power consumption. Data is communicated via standard UART serial interface utilizing standard NMEA-0183 protocols, making integration straightforward with microcontrollers and flight controllers. Onboard EEPROM or Flash memory allows configuration parameters and satellite orbit data to be saved for ultra-fast warm/hot starts.
These modules are widely used in drone flight navigation, vehicle tracking systems, geo-fencing, speedometers, and outdoor IoT telemetry nodes. Operating on 3.3V to 5V power inputs, they are fully compatible with Arduino, ESP32, ESP8266, Raspberry Pi, STM32, Pixhawk/APM flight controllers, and general custom electronics.
