Q: How do measurement errors propagate into GNSS position estimates?
A: Not surprisingly, GNSS positioning accuracy is largely dependent on the level of measurement errors induced by orbital inaccuracies, atmospheric effects, multipath, and noise. This article discusses how, specifically, these errors manifest as position errors.

[Updated June 16, 2014] Sources in Brussels say the recently reported “power loss” that threatens to end the brief transmission life of Galileo GSAT0104, the fourth Galileo in-orbit validation (IOV) satellite, has nothing to do with the onboard atomic clocks, but could have been caused by a failure in the components linked to the solid-state power amplifier (SSPA), including the output multiplexer, cables and/or antenna.
