Hi again

I noticed that the first couple 100 lines in the log shows a predefined GPS altitude of 137 meters. This is before I get a GPS lock.

GPS: 29689583, 0, 6, 0.0000000, 0.0000000, 0, 0.0000, 137.0000, 0.0000, 0.0000
ATT: 37, 30, 21
CTUN:0.00,0.00,0.37,0.00,0.00,0.30,0.00,0.00,0.02,
NTUN: 0.2100, 0, 0.0000, 0.0000, 0.0000, 0.0000, 0.0000,

Just when I get GPS lock both MixAlt and GPSAlt show about the same,

GPS: 29722500, 1, 8, 59.6464580, 17.6274470, 0, 126.1400, 124.9300, 0.0100, 355.3300
ATT: -48, -452, 34283
CTUN:0.00,0.00,-0.48,0.00,0.00,-4.52,0.00,0.00,0.16,
NTUN: -312.5300, 1, 108.4300, 108.4300, -1.1100, 0.0000, 0.0000,

But then a couple of seconds later when I get GPS lock MixAlt is way off (I live approx 35 meters above sea level).

GPS: 29736750, 1, 9, 59.6473850, 17.6280210, 0, 126.0600, 34.7000, 0.0900, 242.6500
ATT: -266, -51, 33029
CTUN:0.00,0.00,-2.66,0.00,0.00,-0.51,0.00,0.00,0.69,
NTUN: -325.0700, 121, 210.9700, 210.9700, -1.0600, 0.0000, 0.0000,

Any ideas?

What is the maximum time Arduplane can log? Yesterday my plane got caught in a tree and it took four hours to get it down - using a chainsaw.

When loading the logs I got "Bad log number" from 2 files och the working log only contained 37 minutes. All including the part where the tree fell to the ground. Approx -1.8 m/s :)

Hmm. Last couple of flights I have not even been able to download the logs. I cleared everything before flight to be sure.Get this text when trying to "Download All Logs" in Mission Planner.

Log number 1,   start page 92,    end page 52

 

Note that end page is lower than start page. Does not seems right.
