Swift Navigation announced that its production-grade State Space Representation (SSR) GNSS corrections service is available in extensive coverage areas: across the continental United States and Europe and in Japan, South Korea and Australia, with plans underway to expand globally.
SSR is a bandwidth-efficient format to deliver GNSS corrections to mass-market applications at scale, suiting it for automotive and mobile customers. As a new option for corrections delivery available through Swift’s Skylark precise positioning service, SSR delivers seamless and homogeneous accuracy throughout a coverage area, according to the company.
To date, Skylark delivered corrections in OSR (Observation State Representation) format for compatibility with legacy equipment. With the introduction of SSR, the cloud error modelling is now available in its native format. SSR provides users with much finer-grained information about GNSS error sources. SSR divides the coverage region into a series of “tiles” which can be broadcast to all users within that tile, enhancing scalability and minimizing bandwidth while maintaining security and privacy.
Swift’s Skylark can deliver bulk corrections data to enterprise customers’ backend for distribution, putting the customer in control of its users’ privacy and security. Swift’s enterprise-reference architecture code equips customers with the SSR Tile Distribution Server software that provides a seamless integration path to incorporate SSR corrections into their own cloud or on-premise solution.
Swift’s SSR solution is based on an open standard from 3GPP. This meets the interoperability requirements demanded by mass-market mobile and automotive applications.
“The ability to deploy SSR to users in a scalable way, while maintaining privacy, makes it possible for automotive, cellular and IoT mass-market customers to integrate precise positioning into their service offering,” said Fergus Noble, Swift Navigation CTO.
Skylark is currently available for integration into wide-area, high-precision positioning applications across the continental United States and Europe and is available in the countries of Japan, South Korea and Australia, with plans underway to expand globally. Skylark is an ever-expanding service and is scalable to service millions of users. All eligible Skylark subscribers begin with a free trial or pilot program.
