A blog post by Maria Simsky from Leuven, Belgium headquartered Septentrio demystifies GPS/GNSS corrections and explains why they are important for user of high accuracy positioning. The demand for high accuracy positioning is growing and spreading from automation and robotization to lawn mowers and other mass market devices. This is driving new developments in the GNSS ecosystem, as new correction services and models emerge to satisfy the demands of various industries. The GNSS corrections ecosystem is currently like the wild west, with little standardization, making it challenging for users to select and connect to the most suitable service. Enter Septentrio’s Agnostic Corrections Partner Program, a bridge between the customer, the receiver and the correction services, that allows integrators to take advantage of reliable high-accuracy receivers in combination with the best suitable correction service.
GNSS corrections are necessary to compensate for variations in satellite signals and atmospheric delays to the radio signal. To achieve decimeter-level accuracy a receiver needs to get external information from a base station or a corrections service. Today there are a range of affordable PPP-RTK (aka SSR) correction services that provide continental coverage, sub-decimeter accuracy and a fast convergence rate. These are delivered over the internet or by satellite. Inspired by the blockchain mining economy, some companies allow users to setup corrections base stations at their home or office. This has resulted in a community-powered, shared network, which has the potential for high density coverage.
The Agnostic Corrections Partner Program was set up to help users navigate the growing maze of correction offerings and facilitate the integration of the right service into the system. GNSS users can select the service which best suits their system requirement and connect it to a receiver for a high degree of positioning reliability and availability. More from Septentrio.
