Final SGL AIRGrav Flight Attitude and Position Data 2008-2009 AGAP-GAMBIT Antarctica Data for Lamont-Doherty Earth Observatory ============================================================================================= AIRGrav_Attitude_Flight_###.xyz - Geosoft format ASCII file --------------------------------------------------------------------------------------------- Col Name Format Units Description --------------------------------------------------------------------------------------------- 1 DATE A9 YYYYMMDD Date 2 DAY A5 DDD Day of year 3 TIME F10.2 seconds UTC seconds past midnight (rolls over) 4 FIDUCIAL F10.2 seconds UTC seconds past midnight (continuous) 5 PITCH F10.3 degrees Laser scanner pitch 6 ROLL F10.3 degrees Laser scanner roll 7 HEADING F10.3 degrees Laser scanner heading 8 LAT1 F15.7 degrees Latitude decimal degrees WGS-84 9 LONG1 F15.7 degrees Longitude decimal degrees WGS-84 10 LAMX1 F15.2 m Lambert conic conformal WGS-84 11 LAMY1 F15.2 m Lambert conic conformal WGS-84 12 WGSHGT F10.2 m Height WGS-84 (height above GRS80 ellipsoid) --------------------------------------------------------------------------------------------- Notes: -Positions are for the laser scanner, not the GPS antenna. -Attitude 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. -10 Hz data rate - 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 1-5 in McMurdo before mobilizing to AGAP 706 Flight 6 in McMurdo after returning from AGAP --------------------------------------------------------------- Sander Geophysics Ltd. 260 Hunt Club Road Ottawa ON K1V 1C1 CANADA Phone: +1 613 521 9626 Fax: +1 613 521 0215 email: info@sgl.com web: www.sgl.com
