GNSS and inertial technologies have a complicated mutual history.
Once competitors for navigation and positioning applications, they now appear ever more frequently in complementary roles — often within the same solution or system design.

The European Space Agency (ESA) today (February 2, 2012) signed a contract to build a further eight Galileo satellites, alongside other agreements to modify Europe’s Ariane 5 launcher to carry four navigation satellites at a time.
The signing took place at the European Commission’s center in London, England, in the presence of European Commission Vice-President Antonio Tajani and UK Universities and Science Minister David Willetts.
Although it was billed as the strongest for the past eight years and coincided nicely with the American Meteorological Society (AMS) annual meeting in New Oreans, this week’s solar storm apparently had a limited effect on GPS receivers and users.
