[DJI-log-discuss] RC_GPS record format

[Brett Spell]

Ross,

 

Here's what I believe to be the format of the RC_GPS (type 11) record found
on older models, and I've also attached a TXT that includes instances of the
record. Note that the first six fields represent a "Startup timestamp" field
that's a bit funky in that it doesn't use epoch milliseconds (or seconds) to
represent a date / time value and is local to GMT.

P.S. I've also seen the record present but with all zeroes for the field
values.
