SBAS Australian-NZ Test Bed: Exploring New Services

Hugo Sobreira, Bruno Bougard, Julián Barrios, Jesus David Calle

Abstract: The GNSS panorama has drastically changed during the last years, with multiple constellations providing PNT services as well as an increasing number of augmentation systems, either already or under development providing SBAS and PPP corrections in different regions around the world. In this context, the SBAS systems are being redesigned to support Dual Frequency and Multiple Constellations (DFMC) augmentation to the GNSS systems. Within the scope of evolving GNSS services, the Australian and New Zealand SBAS test-bed is broadcasting SBAS and PPP corrections over the Asia-Pacific and Australasia areas since September 2017. The early availability of the DFMC SBAS, together with the availability of GEO based PPP corrections, enables the industry to experiment with their solutions, suggest improvements and propose new positioning techniques and applications. It also helps manufacturers to prepare their products for these new services. In this paper, we will analyze the positioning performance obtained with the use of the signals broadcasted by the Australia and New Zealand’s SBAS test-bed (with legacy DO-229, DFMC and PPP corrections) using Septentrio commercial receivers. First, the Septentrio products supporting SBAS L1 have been augmented with the SBAS L5 DFMC functionality. Secondly, through the cooperation of GMV, the PPP information broadcast through the Australian and NZ test-bed has been used to compute a postprocessed PPP solution with the receiver data. The obtained results shall illustrate both the level of performance achieved through the Australian-NZ SBAS-PPP test-bed, and exemplify the maturity of the new services as well as of our rover-side implementation.
