Galileo atomic clocks failed: What can we learn from it?
Publié: mai 3, 2017, 9:30pm CEST par Guy Buesnel
Galileo has been making headlines once again, and this time not for the right reasons. It was reported on January 18, 2017 that several of the atomic clocks responsible for the satellites’ ability to calculate precise time have failed. Timing is everything in GNSS -- very precise time is required to calculate an accurate value of the delay in receiving signals that have been transmitted from a given satellite. This allows users to determine their position on Earth accurately. Also, many applications today take advantage of the very precise timing that GNSS can provide via the atomic clocks in use on… [Continue Reading] -
The main reasons behind the commoditization of Europe's Global Navigation Satellite Systems
Publié: mars 6, 2017, 8:04pm CET par Guy Buesnel
We often hear people say that GPS is ubiquitous, but it is hard to comprehend how without first understanding how GPS technology has evolved and the innovation that is driving applications to make use of GPS derived data. The advent of multi-constellation has been and will continue to be a significant driver in the uptake of GNSS (Europe’s Galileo constellation has finally arrived, starting to offer Early Operational Capability in December 2016). However, the main reasons behind the commoditization of GNSS include several technological evolutions. 1. Improved design for use in consumer electronics Early GPS devices were bulky and heavy, used… [Continue Reading]
