A concept of precise kinematic positioning and flight-state monitoring from the AGMASCO practice

Abstract

A concept of precise kinematic positioning and flight-state monitoring of an airborne remote sensing system is presented here, based on practical experiences 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 developed GPS software package as well as several commercial GPS software packages have been used for data processing. In this paper, the methods of creating the tropospheric model for the aircraft trajectory and the use of static ambiguity results as conditions in the kinematic positioning are discussed. These concepts are implemented in the kinematic GPS software KSGSoft, and have demonstrated excellent performance.
