High-frequency global navigation satellite system’s receivers for airborne gravimetry

摘要

The development of global navigation satellite systems (GNSS) provides a solution of many appliedudproblems with increasingly higher quality and accuracy nowadays. Researches that are carried out byudthe Bavarian Academy of Sciences and Humanities in Munich (BAW) in the field of airborneudgravimetry are based on sophisticated data processing from high frequency GNSS receiver forudkinematic aircraft positioning. Applied algorithms for inertial acceleration determination are based onudthe high sampling rate (50Hz) and on reducing of such factors as ionosphere scintillation and multipathudat aircraft /antenna near field effects.udThe quality of the GNSS derived kinematic height are studied also by intercomparison with lift heightudvariations collected by a precise high sampling rate vertical scale [1].udThis work is aimed at the ways of more accurate determination of mini-aircraft altitude by means ofudhigh frequency GNSS receivers, in particular by considering their dynamic behaviour.
