LiDAR Flight Attitude and Position Data (Level 1)

Level 1 data includes positions are  for the laser scanner, not the GPS antenna (attitude, 10 Hz data rate, is for the laser scanner, not the aircraft). Laser scanner attitudes are offset -0.007 degrees in pitch, -0.348 degrees in roll, and -0.113 degrees in heading compared with the aircraft pitch, roll, and heading.

Lase scanner attitude data are hosted in the following folder:

Name Format Units Description
DATE A9 YYYYMMDD Date
DAY A5 DDD Day of year
TIME F10.2 seconds UTC seconds past midnight (rolls over)
FIDUCIAL F10.2 seconds UTC seconds past midnight (continuous)
PITCH F10.3 degrees Laser scanner pitch
ROLL F10.3 degrees Laser scanner roll
HEADING F10.3 degrees Laser scanner heading
LAT1 F15.7 degrees Latitude decimal degrees WGS-84
LONG1 F15.7 degrees Longitude decimal degrees WGS-84

WGSHGT F10.2 m Height WGS-84 (height above GRS80 ellipsoid)

Some flights are actually two flights processed together. Flights break down as follows:

001 ::: FLT-1 and 2 from Pole to AGAPS
003 ::: FLT-3
004 ::: FLT-4 and 5 (FLT 5 was a compensation)
006 ::: FLT-6
007 ::: FLT-7
008 ::: FLT-8 and 9
010 ::: FLT-10 and 11
012 ::: FLT-12
013 ::: FLT-13
014 ::: FLT-14
016 ::: FLT-16
017 ::: FLT-17 and 18
019 ::: FLT-19 and 20
021 ::: FLT-21 and 22
023 ::: FLT-23
024 ::: FLT-24 and 25
026 ::: FLT-26 and 27
029 ::: FLT-28 and 29 (FLT 28 was a compensation, gravity not processed for that portion of flight)
030 ::: FLT-30 and 31
032 ::: FLT-32 and 33
034 ::: FLT-34
035 ::: FLT-35 and 36
037 ::: FLT-37 and 38
039 ::: FLT-39
040 ::: FLT-40 and 41
042 ::: FLT-42 and 43
044 ::: FLT-44
045 ::: FLT-45
046 ::: FLT-46
047 ::: FLT-47
048 ::: FLT-48 and 49
050 ::: FLT-50 and 51
052 ::: FLT-52
053 ::: FLT-53 (Ferry from AGAP-S to McMurdo)

701-705 ::: Flights 1 to 5 in McMurdo before mobilizing to AGAP

706 ::: Flight-6 in McMurdo after returning from AGAP
