NEO-M8P RTK GNSS receiver board with SMA Base or Rover

NEO-M8P-2 High Precision GNSS receiver EVAL module USB type A connector, I2C, UART, SPI with SMA antenna connectors. Base or Rover operation.

The NEO-M8P modules combine the high performance u-blox M8 positioning engine with u-blox Real Time Kinematic (RTK) technology. The NEO-M8P provides cm-level GNSS performance designed to meet the needs of unmanned vehicles and other machine control applications requiring accurate guidance. u-blox’s RTK technology introduces the concept of a “rover” (NEO-M8P-0) and a “base” (NEO-M8P-2) on the M8 platform for stunning cm-level accuracy in clear sky environments. The base module sends corrections via the RTCM protocol to the rover module via a communication link enabling the rover to output its position relative to the base at cm level accuracies.

The NEO-M8P is ideal for applications requiring vehicles to move faster and more accurately, operate more efficiently, and automatically return to base platforms. Such applications include UAV, unmanned vehicles (e.g. robotic lawn mowers), and Precision Agriculture guidance.

The NEO-M8P modules enable the system integrator to access u-blox complete end-to-end RTK solution including the stationary “survey-in” functionality that is designed to reduce the setup time and increase the flexibility of the application. NEO-M8P modules are compatible with a wide range of communication technologies (Cellular, WiFi, BlueTooth, UHF) enabling the user to select the communication link best suited to their application. With u-blox RTK technology, integration and software development efforts can be reduced, ensuring a minimal cost of ownership.
