Hello,
I am planning to use a novatel oemv receiver as the GPS for my plane. I am using arduplane 2.78 and APM 2.5
I know that ardupilot is happy even with nmea. The question is which $gp... Sentences are enough to be activated in order to do the job.
Thank you

I am back i am also trying to pass the nmea data to apmplane 3.1 with no success. I have a novatel oemv2 l12 receiver. I configured the correct baud rate etc but no luck. I also enabled all the available nmea sentences through the great and very helpfull lefebure conf utility. It is strange as i configured an old lea-4t receiver to output nmea and it worked with the apmplane.....
I will test again the next days and i will report.

samble of nmea output from my lea-4t
Jason,
What is the talker id in the messages? GP, GN, GL?
Which version of firmware are you trying with? I know on Arducopter 3.2rc11 I can't use NMEA anymore.
What are you using if not NMEA?
I'm using a uBlox M8N Concurrent GNSS set for UBX messages instead.
I don't run beta/rc, can you still select between GPS format in the parameters screen on 3.2rc11?
I once used the APM2 / Ublox .hex in uCenter to see what the default ardupilot settings were and remember seeing the enabled sentences. I will look again when I get home as navspark is sending me a free gnss/glonass receiver that I want to use for the 2nd gps on my pixhawk and will need to also know this info. Does that receiver do glonass as well? And do you know if the pix/apm2 can use gngsa, glgsa, and glgsv?
I'm interested if you got your NavSpark going. I have two NavSpark GL units and when set to use both GPS and Glonass, it cold boots to a HDOP of 1.4 in 32s. Wait 10s more and I've got a HDOP of 0.6/0.7. I've just started looking into whether or not ArduCopter can connect to a NavSpark.
