Product description:

The NEO-M8P module combines the high performance u-blox M8 positioning engine with u-blox’s 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.

Communication Link-Hardware-Pro

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 station 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 station at cmlevel accuracies.

The NEO-M8P is ideal for applications requiring vehicles to move faster and more accurately, operate without physical boundaries (e.g. wires or fences), and automatically return to base station platforms. Such applications include UAV, unmanned vehicles (e.g. robotic lawn mowers), and Precision Agriculture guidance. The NEO-M8P module enables the system integrator to access u-blox’s complete  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’s RTK technology, integration and software development efforts can be reduced, ensuring a minimal cost of ownership. u-blox M8 modules use GNSS chips qualified according to AEC-Q100, are manufactured in ISO/TS 16949 certified sites, and fully tested on a system level. Qualification tests are performed as stipulated in the ISO16750 standard: “Road vehicles – Environmental conditions and testing for electrical and electronic equipment”.
