Abstract

New GNSS systems (i.e. GPS modernization, BeiDou, and Galileo) will provide multiple navigation signals for reliable navigation services. The triple or even multiple frequency signals are expected to bring great benefits to the ambiguity resolution (AR) over long baselines, which is always regarded as a huge challenge. A new triple-frequency, ionosphere-free technique for ambiguity resolution of long-range baseline are developed in this study. In this technique, the optimal observation combinations are chose considering the effect of ionospheric delay. At the same time, using this technique, the double difference (DD) ionospheric delay can be nullified in the ambiguity search process.
