PPP-RTK by means of S-system theory: Australian network and user demonstration
MetadataShow full item record
The development of an Australian PPP-RTK processing platform is an important component of a multi-GNSS (global navigation satellite system) enabled national positioning infrastructure. The PPP-RTK concept extends the precise point positioning (PPP) concept by providing single-receiver users with information enabling integer ambiguity resolution, thereby reducing convergence times as compared to that of PPP. In this contribution we present and discuss the underlying principles of the PPP-RTK platform for both network and user. We demonstrate its GPS-based performance and provide an outlook for when multi-GNSS constellations, such as BDS, Galileo and QZSS, become fully operational.

Khodabandeh, Amir; Teunissen, Peter (2016)PPP-RTK has the potential of benefiting enormously from the integration of multiple GNSS/RNSS systems. However, since unaccounted inter-system biases (ISBs) have a direct impact on the integer ambiguity resolution ...
Odijk, D.; Teunissen, P.; Khodabandeh, Amir (2014)Integer ambiguity resolution enabled Precise (cm-level) Point Positioning (PPP) is feasible if corrections from a GPS network of CORS stations are applied to the single-receiver phase and code data of a user. The concept ...
Teunissen, Peter; Khodabandeh, A. (2014)All rights reserved. In this contribution we study the impact of integer ambiguity resolution (IAR) on the precision of GNSS estimable parameters. In doing so, a multivariate formulation of the GNSS undifferenced observation ...
