- Communication protocol:
Microduino NEO-6M module use NMEA-0183 protocol and output GPS data, using the UBX protocol to configure the module.
- Reception characteristics
50 channels,GPS L1(1575.42Mhz) C/A ç ,SBAS:WAAS/EGNOS/MSAS
Capture tracking sensitivity:-161dBm
2.5 mCEP (SBAS:2.0mCEP)
Maximum 5Hz
cold start:27S(Fastest time)
warm start:27S
hot start:1S
Cold start means that module stored history information which GPS receiver has lost (corresponding to the main power supply and battery both lost power), then restart the module, called cold start.
Warm start means that the is the module saved the historical information, but this information is inconsistent with information of currently visible satellites, and under such conditions to start module, called warm start.
Hot start means that module stored GPS history information which consistent with the currently visible satellite's information, then restart the module, called a hot start.
- Interface characteristics
TTL,compatible 3.3V/5V microcontroller system
Serial communication baud rate:
Microduino NEO-6M module supports several baud rate:4800ã€9600ã€38400(defult)ã€57600ï¼›
