Fenix Processing
aplnav returned error: "Requested sync time index is out of bounds in GetSyncDelay()", so processing without nav.

comment:2 Changed 2 years ago by lah

Fenix Processing
Found SCTs for boresight lines:

Flightline FENIX
5 2.31
6 30.60
7 3.13
8 3.77
9 2.71

Fenix Processing
Found boresight values: 0.08 0.13 0.32 and tested on extra lines. Needed line 10 for decent overlap to check heading as line 9 was short and didn't have useful overlap. Final scts:

Flightline FENIX
1 2.93
3 4.90
4 3.15
5 2.31
6 30.56
7 3.15
8 3.77
9 2.77
10 12.16

Navigation processing
This was done ages ago but I didn't make a not here:

basestation (OXFR):

Lat 51 49 26.25421
Long -1 17 18.72265
Height 119.763

Actual nav data resulted in a good solution with default IPAS TC settings.

This was processed using old lever arm values until the survey data is available.

Lidar processing
Processing has resulted in one value for pitch and 2 values for roll dependant on flightline altitude.

pitch -0.00226
roll low -0.00093
roll high -0.00106

heading has a value of 0 until confirmed otherwise

Lidar Processing

Range corrections:

A1 -2.153
A2 -2.109
A3 -2.122
A4 -2.178
B1 -2.153
B2 -2.204
B3 -2.151
B4 -2.117

These were checked for variations at different altitudes to try and explain the variable roll. There was no difference found.

Waveform trigger delay offsets:

under TPR 6750
over TPR 8200

Forward laser angle value has not been used for this calibration to ensure compatibility with alsproc.

Owl Boresight

owl_boresight = -0.08 -0.08 0.16

SCTs:

Flightline OWL
3 2.48
4 3.24
5 2.90
6 2.45
7 3.04
8 2.35
11 2.76
