Multi-GNSS PPP-RTK Network Processing

The multi-GNSS PPP-RTK network processing platform will form a critical component of the CRCSI’s Analysis Centre Software (ACS). The project consists of the following two subprojects: (1) PPP-RTK network and (2) Multi-GNSS integration.

The goal of Subproject (1) is the algorithmic development of the PPP-RTK network processing platform. It will deliver as output the numerical estimation and quality description of the following network parameters for the GNSS satellites and network tracking station receivers: (a) satellite and receiver clock errors; (b) multi-frequency satellite and receiver code biases; (c) multi-frequency satellite and receiver phase biases; (d) ionospheric delays; (e) zenith tropospheric delays.

The goal of Subproject (2) is to develop the PPP-RTK network processing platform further so as to admit any of the multi-GNSSs, stand-alone or in combination. These two research goals take on particular significance in the Australian context, given current GNSS/RNSS development in the Asia-Pacific region and the fact that a national CORS network will inevitably have interstation distances greater than those used in geographically smaller and more densely populated regions of the world. This project will capitalise on collaboration with international GNSS/RNSS receiver and software providers to focus on the unique Australian situation.
