I'm sorry if this comes to wrong forum, but here goes.
I got this new action camera which tracks the following kind of data (edited):
$OLTIM,20170224,045641// Time obviously, no probs here $OLCMP,23.7 // Compass $OLPRE,963,421.2,1389.9 // Pressure $OLTMP,20.5,1,0 // Temperature in F's, no probs here $OLACC,-1007.1,-3.6,4.7 // Acceleration -- $OLTIM,20170224,045712 $OLCMP,24.2 $OLPRE,963,422.0,1392.6 $OLTMP,20.5,1,0 $OLACC,-1007.1,-3.6,8.5 -- $OLTIM,20170224,045743 $OLCMP,23.2 $OLPRE,963,419.5,1384.4 $OLTMP,20.5,1,0 $OLACC,-1003.1,-3.6,4.7 -- $OLTIM,20170224,045814 $OLCMP,24.3 $OLPRE,963,422.2,1393.3 $OLTMP,20.5,1,0 $OLACC,-1007.1,-3.6,4.7 -- $OLTIM,20170224,045846 $OLCMP,24.5 $OLPRE,963,419.3,1383.8 $OLTMP,20.5,1,0 $OLACC,-1007.1,-3.6,4.7 -- $OLTIM,20170224,045917 $OLCMP,256.5 $OLPRE,963,423.4,1397.3 $OLTMP,20.5,1,0 $OLACC,274.5,-901.2,-116.8 -- $OLTIM,20170224,045938 $OLCMP,273.4 $OLPRE,964,415.8,1372.2 $OLTMP,20.5,1,0 $OLACC,405.5,-878.4,168.1
I've maneged to solve this:
- first digits (963) of
$OLPREmust be the average air pressure in hPa
For this, I've got a hunch:
$OLACCcould refer to x,y & z accels
Conditions when data was captured:
- Outside, ~ -7c
- ~95m (312ft) over sea level
- Clear sky
So the question is:
Any ideas what
$OLCMP and the second digits of
$OLPREwould stand for? And the rest too actually.
