Results On Australia And New Zealand Second Generation SBAS And PPP Augmentation System
Résumé
During 2017 and 2018 a second generation satellite positioning augmentation system is being demonstrated in Australia and New Zealand. This system provides Satellite Based Augmentation (SBAS) and Real Time
Precise Point Positioning (PPP) capabilities through the SBAS L1 and L5 signals broadcasted from the Inmarsat 4F1 geostationary satellite.
The Australia and New Zealand SBAS and PPP testbed is promoted by Geoscience Australia (GA), Land Information New Zealand (LINZ), and the Australia and New Zealand Cooperative Research Centre for Spatial Information (CRCSI). The system is developed in collaboration with industry partners, including Lockheed Martin, Inmarsat and GMV.
The services and signals broadcast during the testbed consist of:
- SBAS L1 legacy service available for GPS L1 singlefrequency users over Australia and New Zealand.
- SBAS DMFC L5 service available for GPS L1/L2 + GAL E1/E5a dual-frequency users over the Inmarsat 4F1 footprint.
- PPP corrections through SBAS L1 message, targeting GPS L1/L2 dual-frequency users
- PPP corrections through SBAS L5 message, targeting GPS L1/L2 + GAL E1/E5a dual-frequency users.
The transmissions of SBAS signals started in May 2017, while the transmission of the PPP services started in October 2017.
The main goal of this paper is to provide, from the point of view of the system developers, an update on the testbed service definition, infrastructure status and performances achieved during the 2017-2018 system operation.
