Abstract: New high accuracy Precise Point Positioning (PPP) services, like Galileo High Accuracy Service (HAS), BeiDou PPP-B2b and QZSS-CLAS/MADOCA-PPP are designed to broadcast GNSS corrections directly through specialized signals components. These correction data streams are formatted according to a very efficient State Space Representation (SSR), with some peculiar differences and declinations among the three GNSS systems. In this paper, the new single chip (STA8135GA) from STMicroelectronics is introduced as a low-cost, triple-band hardware platform to support multiple, integrated high accuracy services. The main target application is autonomous precise positioning and navigation at the decimeter-level accuracy, for the automotive, industrial and consumer markets. The SSR transport performances are crucial to guarantee a constant and updated flow of corrections and will be evaluated in terms of received frame rates. The goal of the proposed platform is to provide, at the same time, accurate dual-band observables and a reliable SSR stream to the PPP client, harmonizing protocols and applicative interfaces when possible. The positioning accuracy improvement given by the correction services over broadcast navigation data represents the main objective of this paper, which also validates the full end-to-end processing.
