Galileo atomic clocks failed: What can we learn from it?

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]
