GNSS antenna array-aided CORS ambiguity resolution

摘要: Array-aided precise point positioning is a measurement concept that uses GNSS data, from multiple antennas in an array of known geometry, to realize improved parameter estimation proposed by Teunissen (IEEE Trans Signal Process 60:2870–2881, 2012). In this contribution, the benefits array-aided CORS ambiguity resolution are explored. The mathematical model formulated show how platform-array data can be reduced and variance matrix between-platform ambiguities profit increased precision platform data. performance will demonstrated for varying scenarios using simulation. We consider single-, dual- triple-frequency geometry-based geometry-free models different number standard deviations ionosphere-weighted constraints. performances both full partial (PAR) presented these scenarios. As study shows, when advantage taken antennas, significantly improved, some important cases even enabling instantaneous resolution. PAR widelaning its suboptimal character hereby also illustrated.
