利用无几何的短基线和零基线分析方法，可以准确地估计全球导航卫星系统测距的随机特性。这种方法现在被应用于一项新的野战中的双频测量。除了GPS L1C/A和GIOVE E1B信号外，还给出了新的GPS L5Q和GIOVE E5aQ宽带信号的结果。正如预期的那样，结果清楚地显示了新信号的高精度，但它们也显示，相当出人意料的是，伪距码测量值的显著、缓慢变化的变化可能是数据上强烈的多径干扰的结果。对两个频率上的载波相位测量噪声进行了评估，并成功地实现了GPS-GIOVE双差模糊度的混合解算。
Stochastic properties of GNSS range measurements can accurately be estimated using a geometry-free short and zero baseline analysis method. This method is now applied to dual-frequency measurements from a new field campaign. Results are presented for the new GPS L5Q and GIOVE E5aQ wideband signals, in addition to the GPS L1 C/A and GIOVE E1B signals. As expected, the results clearly show the high precision of the new signals, but they also show, rather unexpectedly, significant, slowly changing variations in the pseudorange code measurements that are probably a result of strong multipath interference on the data. Carrier phase measurement noise is assessed on both frequencies, and finally successful mixed GPS-GIOVE double difference ambiguity resolution is demonstrated.
