The NEO-M8N GPS module with ceramic active antenna is a robust and versatile solution for global navigation satellite system (GNSS) applications. The listing describes concurrent reception of multiple GNSS systems, integrated flash memory for firmware updates and compatibility with u-blox's AssistNow assistance service for a shorter time to first fix.
The receiver is a 72-channel u-blox M8 engine, and the module can receive up to three GNSS systems concurrently. It advertises advanced jamming and spoofing detection and support for satellite augmentation systems.
It is backward compatible with the NEO-7, NEO-6 and NEO-5 families, which makes it a practical upgrade path for existing designs that used an earlier u-blox module.
Concurrent GNSS reception: up to three systems at the same time.
High navigation sensitivity: tracking sensitivity of -161dBm per the specification table.
Jamming and spoofing detection: helps reliability in difficult environments.
Backward compatible: with the NEO-7, NEO-6 and NEO-5 families.
Satellite augmentation support: improved accuracy where available.
Active ceramic antenna included: ready for use.
A GPS module listens to signals from navigation satellites and works out its position, speed and time. A flight controller or microcontroller uses that position for modes such as position hold, waypoint missions and return-to-home, or simply for logging where something has been. Supporting several satellite constellations means more satellites in view, which usually gives a faster and more reliable fix.
Mount the module as far as practical from motors, power wires and video transmitters, with a clear view of the sky, and let it get a full satellite lock before you rely on it. Poor mounting and interference are more common causes of GPS problems than the module itself. Keep the antenna face pointing up and secure the module so vibration does not shift it.
A first fix can take longer than later ones, particularly indoors or after the module has been off for a long time. A module with a backup battery or stored configuration can start faster the next time, but you should always wait for a solid lock outdoors before the first flight of the day.
