Data location: ~arsf/arsf_data/2011/flight_data/arsf_internal/GB11_00-2011_082_little_riss

Data arrived from ARSF via network transfer on 24/03/11.

Scientific objective: N/A (calibration flight)

Priority: Immediate

Calibration flight

Sensors:

• Eagle (done)
• Hawk (done)
• Leica LIDAR (done)
• RCD (done)

Note Eagle and Hawk raw file names both had incorrect naming convention, have amended the raw filenames

The repeat flightlines are 4 and 23, both of which go South at ~750m.

[knpa]

There are very large SCT offsets for the two lines produced so far (4 and 23, both Eagle and Hawk). This is unusual in that this degree of error is usually only present when no sync information is available, however no such error was reported and the lines processed through cleanly.

[knpa]

Large offset was found to be due to AZ not applying an offset of 15 leap seconds which is necessary when converting to UTC from GPS time. Bill will look into this problem when we send him some sample files.

[knpa]

Bill has found the problem and will send us corrections with the next software update.

Roll issue as described here #257 is still present in this data.

Data has also been made available to Leica Support.

Eagle/Hawk have been boresighted using the IPAS IMU SOL -> SBET navigation

with the below leverarms;
eagle_leverarm = 0.415 -0.014 -0.129
hawk_leverarm = 0.585 -0.014 -0.129

and resulted in the below boresight offets (PRH);
eagle_boresight = -0.322 0.175 0.38
hawk_boresight = -0.345 0.29 0.35

[iopa]

Eagle & Hawk SCT offsets for the lines used for boresighting, used with aplsuite, these offsets include the global -0.055
