The SmartElex NEO-M9N GPS breakout board is a high-performance GNSS receiver module designed for reliable and accurate positioning. It uses the u-blox M9 engine and supports GPS, GLONASS, Galileo and BeiDou constellations simultaneously.
The board delivers up to 1.5 metre accuracy and offers multiple interfaces, including UART and I2C, for integration with Arduino, Raspberry Pi and other systems.
Advanced jamming and spoofing detection and an onboard rechargeable battery for quicker hot starts round out the feature set, and an SMA connector lets you attach an external antenna.
92-channel u-blox M9 receiver: high accuracy positioning.
Four constellations at once: GPS, GLONASS, Galileo and BeiDou.
About 1.5m accuracy, up to 25Hz: responsive tracking.
SMA connector: use an external antenna.
Rechargeable battery: faster hot-start positioning.
Jamming and spoofing detection: reliability in interference-prone areas.
UART and I2C: flexible integration.
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.

The specification table lists a maximum altitude of 80,000m, a maximum velocity of 500m/s, a velocity accuracy of 0.05m/s, a heading accuracy of 0.3 degrees and a time pulse accuracy of 30ns.
The package includes the breakout board and berg pins with a connecting cable. An external antenna is not listed, so plan to add your own SMA antenna.
