bu-353 gps

I have the small puck type device installed and running with the data showing in the data window with the correct comm port, windows sensors checked for use gps.  The driver is the 2007 version to get the puck working.

however,  no position fix found by Exp.  What am I missing?

Thx, pjl

Re: bu-353 gps

If it is appearing as a comm port, you definitely don't want to treat it as a Windows sensor.

If you have data on the raw data feed, you need to look at the GPS sentences in that. You could also post a sample here.

Re: bu-353 gps

the puck is on comm 8, running the data stream.  I will try to cut and paste, but also, how do I attach a file to this note?  (Sorry about my nav skills).

Re: bu-353 gps

It might not have been a valid fix? The GGA sentence above looks ok at first sight.

Re: bu-353 gps

do u think that the reboot and restart of Exp had a role in the success?

The gga sentence is different in the two different instances of the raw data flow.  the first group gga sentence seems incomplete.

Thx, pjl

Re: bu-353 gps

Re: bu-353 gps

There isn't, mostly because it isn't human readable.
