China launched a new-generation satellite into orbit that will support its GNSS network at 7:13 a.m. Beijing Time Wednesday, September 30, 2015.

According to the China state news agency Xinhua, the spacecraft was launched from Xichang Satellite Launch Center in the southwestern province of Sichuan on a Long March-3B carrier rocket. It was the 20th satellite for the BeiDou Navigation Satellite System (BDS) and for the first time featured a hydrogen atomic clock.

Privacy Hard to Maintain as Apps Gather GNSS Location Data for Retailers, Crowd-Sourcing

The average person with a smart phone has their location revealed every three minutes, according to a recent study, information that can be determined even if GNSS capabilities are turned off, experts said.
 
Research published last year by Carnegie Mellon, showed that, overall, “somebody or something was trying to get your location” every three minutes, said Logan Scott, an expert in GPS, cellular and wireless technologies. “Over a space of two weeks the average is about 6,200 position reports coming out of that (phone).”

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.
