Hey guys! I will use M9N but I read a thread about its Compatibility with ArduCopter software. By the way I will use PixRacer as some of you know. Will there be any compatibility issues with it ??

well, im using mro LocationOne equipped with the ublox m9n without any issue.
You will not have any issue on your fc… just look for the serial… aside you want start use CAN BUS protocol

Thanks man! What about its update rate can it update at 25 hz?

On the paper, could be possible. When setting it with UBlox utility, there are some glitch in satellite data display. Work fine at 10Hz (GPS+Glonass+Galileo+SBAS).

Do you have any info about mRo Neo M9N

My M9Ns (Matek, Matek-CAN, Drotek) show at most 16 Sats in Mission Planner and QGC.
I have 4 constellations active, which should receive more than 30 sats.
Anybody else?

Good day,
me I’ve the mRo LocationOne with m9n…,
This gps is CAN protocol.
I’ve choose CAN coz its more fast and with less interferences.
The must of this gps its not only the m9n that is more fast and precise, but also you have the geomagnetic sensor… rm3100.

Could you please re-check the question.

its the same module like the LocationOne but its serial…

Thanks, mate! Appreciated

The mRo m9n gps have two compasses… for provide more redundancy, plus you have the safety switch integrated.
The module perform well… fast gps acquiring

Hello,
Currently I am using CUAV NEO 3 M9N GNSS module but while connecting it with Pixhawk v6x through GPS & Safety switch and connecting whole system to mission planner, I am getting an error of ‘GPS: NO Fix’. I am using mission planner version 1.8.32 and Arducoptor version 4.5.7. I made the settings of mission planner as

CAN_D1_PROTOCOL = 1
CAN_D2_PROTOCOL = 1
CAN_P1_DRIVER = 1
CAN_P2_DRIVER = 1
GPS_TYPE = 9
GPS_TYPE2= 9
NTF_LED_TYPES = 231

Port selected is : COM7 (ArduPilot MAVLink)

My system is not showing ‘com.hex.here’ file when I select SETUP->Optional Hardware->DroneCAN/UAVCAN-> MAVLink-CAN1.

How to resolve this issue and enable GPS?

Hello,

CUAV NEO 3 M9N GPS is a serial GPS. (PRO is with a CAN interface)

So you have to set the Com port 3 (default for first GPS and multi use 10 pins plug)
SERIAL3_PROTOCOL =5,

and GPS_Type =1 (Auto) or 2 (uBlox)
