NEO-M9N GPS 모듈 -칩 안테나
(SparkFun GPS Breakout - NEO-M9N, Chip Antenna (Qwiic))
개요
- 본 제품은 칩안테나를 보드상에 장착하고 있는 NEO-M9N GPS 모듈입니다.
- NEO-M9N은 92채널 u-blox M9 엔진 GNSS 리시버로 GPS, GLONASS, Galileo, BeiDou 위성신호를 수신할 수 있습니다.
- 4개의 GNSS 신호를 동시에 수신하는 것을 지원하여 위치정보의 정확도를 높일수 있으며, 보드에 장착된 배터리를 이용하여 GPS가 수초이내에 hot start 될수 있게 하여 줍니다.
- I2C 인터페이스를 지원합니다.

The NEO-M9N module detects jamming and spoofing events and can reports them to the host, so that the system can react to such events. A SAW (Surface Acoustic Wave) filter combined with an LNA (Low Noise Amplifier) in the RF path is integrated in the NEO-M9N module which allows normal operation even under strong RF interferences.
U-blox based GPS products are configurable using the popular, but dense, windows program called u-center. Plenty of different functions can be configured on the NEO-M9N: baud rates, update rates, geofencing, spoofing detection, external interrupts, SBAS/D-GPS, etc. All of this can be done within the SparkFun Arduino Library!
The SparkFun NEO-M9N GPS Breakout is also equipped with an on-board rechargeable battery that provides power to the RTC on the NEO-M9N. This reduces the time-to-first fix from a cold start (~24s) to a hot start (~2s). The battery will maintain RTC and GNSS orbit data without being connected to power for plenty of time.
