GPSout and gpgga


Recommended Posts

Hi,

I've been trying to get NavGPS for pocket pc to work with

FS2004.

I've configured gpsout as follows:

Sentences=GGA,RMC

Interval=1000

Port=COM1

Speed=4800

Problem is that NavGPS keeps telling me:

"Waiting for NMEA gpgga"

NavGPS maker Snowlion tells on their site:

"Do you see the message 'Waiting for NMEA gprmc'?

Do you see the message 'Waiting for NMEA gpgga'?

If yes...that means that these required NMEA message is not being received. On some gps receiver units, you also have to enable the transmission of message types individually. Otherwise, you'll have to check the gps receiver manual and make sure that these messages are supported."

What might be wrong?

Sorry, I don't know. Is the Speed correct? Is the COM port correct? Most importantly, is the connecting cable correct? I didn't know that Pocket PCs came with a regular COM port. Have you checked that you are communicating correctly? Is there anything for the Pocket PC that can check and display what it is receiving?

Also, you don't mention which version of GPSout you are trying, nor which version of Flight Sim. These things might be relevant.

I use GPSout with GGA and RMC sentences all the time, connecting to Jeppesen FliteMap on another PC, and it does work. The communications need verifying.

Regards,

Pete

Hi Peter and thank you for answering.

I've tried GPSout 2.55 with Flight Simulator 2004. COM-port, speed and connection cable are 100% correct. I was mostly unsure about the sentences defined in gpsout.ini (and yes, my Ipaq 3630 uses serial connection :) )

My point was, that the maker of NavGPS claims NMEA messaging style of GPS equipment (in this case GPSout) doesn't follow the standards. This is something I hope you can answer as you're the creator of gpsout. Does GPSout NMEA messaging meet the standards?

If it does, I'm done here and I should start to bomb NavGPS manufacturer with my questions :D

Yes. Here is a sample the the output as received and processed correctly by Jeppesen FliteMap, with the settings I use, for instance:

$GPRMC,122119.00,A,5324.1111,N,00212.6492,W,240.1,45.0,130204,6.1,W*6D

Show that to the NavGPS folks if you like.

If it does, I'm done here and I should start to bomb NavGPS manufacturer with my questions :D

I think first you need to verify the connection. There is a MUCH greater likelihood of it being something wrong in the connection than anything else. The rest is really too simple to be likely to be wrong. Have you any simple program for the PocketPc which will show what is being received on the COM port? There is no other way I know to check this.

Regards,

Pete

Thanks for sample, I'll show it for NavGPS staff if I can't figure anything else out.

I've tested Memory Map Navigator in my pocket pc and it works just fine with GPSout so propably there is something wrong either on NavGPS settings or the program itself.

Once again thank you very much for all your help.
