Atmospheric Case 15: F-16, North Pole Circumnavigation
Atmospheric scenario 15 tests propagation difficulties near 90 deg latitude and proper longitudinal position wrapping as the IDL is crossed at ±180 geodetic longitude.
Constants and Models
This scenario uses a F-16 vehicle model, specified here. The 1976 STD atmosphere model defines atmospheric properties at various altitudes, specified here. The F-16's source of gravity is the J2 gravity model, specified here. The geodesy model used for this scenario is the WGS-84 rotating model, specified here.
