Re: [gpsd-dev] [PATCH] [log.chk] [TPV timing] implement $GPVTG message, and proper timing for output "TPV" messages

[teyrana]

Hey guys,

I was looking through gps.h, and I notice that " struct navdata_t {" @ line 1849 has a 'compass_heading' field. Are you okay with storing the GPVTG data there?

Cheers,

-Dan

p.s. FYI: compass 'dip', (aka compass inclination) is in the 'struct attitude_t', while the other compass deviation & variation are in the different struct: 'navdata'.

You are right, no good place.  After your patch gets added to git head
I'll add a trackmag to the TPV message.
