Don’t Dump That Data!: Thorough Use of GNSS Measurements

A constantly recurring refrain within the satellite navigation community is the self-evident observation that, with more satellites, constellations, and frequencies appearing over the next few years, GNSS performance will improve.

Until those expectations become reality, though, another major opportunity is being almost universally overlooked: making far more efficient use of all the GNSS measurement data we have available right now.

Don’t Look Back

It might have been the segment from Martin Scorsese’s documentary on Bob Dylan, which I saw recently, that made me think of using this title for my comments.

Galileo Light Show: First Laser Range Measurements to GIOVE-A

European researchers have obtained laser range measurements of 1.5-centimeter accuracy to GIOVE-A, the first element in the Galileo In-Orbit Validation phase. The observations were made through collaboration between the UK Space Geodesy Facility (SGF), Surrey Satellite Technology Limited (SSTL), and the European Space Agency (ESA). The SGF is operated by the UK Natural Environment Research Council, with support from the British National Space Centre and the Ministry of Defence.
