DoT Hastens GNSS Receiver Testing for Adjacent Band Compatibility Assessment

Federal officials have released a draft of their plan to determine the amount of interference satellite navigation receivers can tolerate from users in neighboring frequencies. The tests, proposed after the Federal Communications Commission (FCC) froze a controversial wireless broadband system, would accelerate research on GNSS receivers that process signals from multiple satellite constellations.

Urban Localization and 3D Mapping Using GNSS Shadows

It is by now well known that GNSS-based localization in built-up urban environments can be extremely inaccurate. This is a fundamental problem that hardware enhancements cannot solve.

A GNSS receiver estimates 3D location and timing from pseudoranges from four or more satellites, assuming that these pseudoranges correspond to direct line-of-sight (LOS) paths from each satellite. In urban canyons, however, the signal from a satellite to the receiver suffers from multipath propagation and shadowing.
