First results of mixed GPS+GIOVE single-frequency RTK in Australia
MetadataShow full item record
First results are presented for precise (mm/cm-level) short-baseline RTK positioning based on single-frequency GPS data combined with data of GIOVE-A/B, the two experimental Galileo satellites, collected in Australia. The paper first focuses on the model of GPS+Galileo observation equations and addresses the issues that arise when combining data of both systems, in particular the inter-system biases (ISBs). Our results indicate that the differential ISBs are quite stable in time, potentially enabling calibration and a priori correction of the Galileo phase and code observations. Based on ISB-corrected data, there liability of single-frequency GPS+GIOVE ambiguity resolution is significantly improved, when compared to GPS only.

Characterization of between-receiver GPS-Galileo inter-system biases and their effect on mixed ambiguity resolutionOdijk, Dennis; Teunissen, Peter (2013)The Global Positioning System (GPS) and Galileo will transmit signals on similar frequencies, that is, the L1–E1 and L5–E5a frequencies. This will be beneficial for mixed GPS and Galileo applications in which the integer ...
