Adding Glonass to the GPS/Galileo consumer receiver, with hooks for Compass

摘要

The paper discusses the need for multi-constellation receivers to make more satellites available in urban canyon environments, where only a partial view of the sky is available and where extreme integrity is required in order to reject unusable signals, while continuing to operate on other signals deeply degraded by multiple reflection and attenuation. It covers the difficulties of integrating a non-compatible system, offering an economic solution in the mass-market where cost is king, but performance demands in terms of low-signal, power consumption, TTFF and availability are extreme, and while accuracy is not at survey levels, must meet consumer demands even at the worst signal conditions.
