A concept of precise kinematic positioning and flight-state monitoring of a
n airborne remote sensing system is presented here, based on practical expe
riences from the EU project AGMASCO. Within the project about two months of
kinematic GPS flight data and static reference data have been collected in
Europe over four campaigns during the past three years. An independently d
eveloped GPS software package as well as several commercial GPS software pa
ckages have been used for data processing. In this paper, the methods of cr
eating the tropospheric model for the aircraft trajectory and the use of st
atic ambiguity results as conditions in the kinematic positioning are discu
ssed. These concepts are implemented in the kinematic GPS software KSGSoft,
and have demonstrated excellent performance.
