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.

AGNSS Standardization

Location technology is entering ever more deeply into our day-to-day lives. Growing market demand for location-based services (LBS) revolves the single premise: “Location everywhere, any time.” The requirement for seamless, ubiquitous positioning includes, of course, urban and indoor environments.

Allison Kealy: The Remarkable Art of the Possible

Allison Kealy caught the GNSS bug at age 18 while waiting beneath the starry skies of Trinidad for the moment when enough satellites would become available to allow an Ashtech receiver to compute her position. Up to that point, her training as a surveyor was limited to land-based equipment.

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.

More likely, however, it’s an echo from my long-gone days on the running track where any athlete worth his or her salt knows that when you come to the final stretch of the race, you shouldn’t look behind yourself.

BOC or MBOC? Questions and Answers

Global navigation satellite systems are all about timing. In a narrow sense, GNSS is technically a matter of how long the satellite signals take to reach a receiver. In a larger sense, it’s about designing global infrastructure systems that may not produce practical benefits for 5, 10, even 15 years or more.

During that time, a lot can happen. Technology changes. Electronics get more powerful and cheaper.

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.
