Why are we talking about Multi GNSS?
Navigation and positioning technology is no longer just about GPS L1 C/A code. GPS is being modernized, the GLONASS constellation is nearly complete, new systems including QZSS, Galileo and Compass are on the way.
The Global Navigation Satellite System (GNSS) landscape has never looked so active with GNSS applications becoming more mainstream and available in a growing number of devices. A technology originally dictated by military requirements is now widely viewed as strategic to support economic growth driven by the commercial market. The result is a choice of current and planned constellations from around the world; Europe, China, Russia and USA all now recognise that GNSS is strategic and are each investing to support this growing industry.
What effect will this have on GNSS developers and integrators?
Multi-GNSS offers significant opportunities and challenges to GNSS technology, system and application developers. As navigation and positioning applications become more widespread, end user demands are increasing. Multi-GNSS offers opportunities to improve performance to meet increasing user demands. In particular, availability is potentially improved by using more than one constellation. Benefits can also include improved integrity, continuity and accuracy, depending on the situation and priorities of the application.
“In future, most receivers will be Multi-GNSS, many will also be using augmentation as a key aspect of the navigation or positioning solution. Multi-frequency GNSS will increasingly be used to support applications requiring sub-metre accuracy.”
A significant amount of research and development is currently underway by the technology and applications development community to respond to the opportunities that this expansion in operational capabilities affords.
