3DR GPS u-Blox Neo-M9N - IST8308 GPS Receiver
by 3DR

The 3DR GPS u-Blox Neo-M9N - IST8308 is an exceptionally powerful GPS and compass module built around the robust u-blox NEO-M9N GNSS chip. Designed for precision navigation in standard UAV and robotics applications, this module provides meter-level accuracy by tracking multiple satellite constellations concurrently. By utilizing GPS, GLONASS, Galileo, and BeiDou simultaneously, the receiver maximizes the number of visible satellites, which drastically improves position accuracy and acquisition times—especially in challenging environments like deep urban canyons.

In addition to the high-performance GNSS engine, this module features an integrated IST8308 compass for accurate heading data. The hardware is thoughtfully designed with a 40mm x 47mm ground plane to optimize antenna reception. It also includes an integrated RGB LED driver for visual status indication, an onboard safety switch, and an accessible PPS pad. With its lightweight design and standard JST-GH connectors, it is a versatile and reliable choice for a wide variety of autonomous platforms, from multirotors and fixed-wing planes to rovers and automated tractors.
