Test Shows Galileo Increases Accuracy of Location-Based Services

May 27, 2014By

The European GNSS Agency (GSA) and Rx Networks Inc., a mobile location technology and services company, announced the results of tests conducted by the company measuring the performance of Galileo when used in various combinations with GPS and GLONASS. Tests were conducted in real-world environments, including urban canyons and indoors. These environments pose significant challenges to location accuracy due to multipath... read more

Spirent’s SimSAFE Fights Signal Vulnerability

March 1, 2014By

By Tracy Cozzens Spirent Communications now offers SimSAFE, a software solution that simulates legitimate GNSS constellations along with spoofed or hoax signals to evaluate receiver resilience and help develop counter measures. Hoax or spoofing attacks work by mimicking genuine GNSS signals, which mislead GNSS receivers.  The military and critical infrastructure — such as wireless networks, banking, and utilities — are especially... read more

February 13, 2014By

STMicroelectronics, a global semiconductor company, has released its Teseo II single-chip satellite-tracking integrated circuit to the European Space Agency (ESA) and the European Commission Joint Research Center (JRC) for testing for eCall approval. The testing campaign is coordinated by the European GNSS Agency as part of its effort to accelerate Galileo adoption. The Galileo tests will be conducted by the... read more

Consumer GPS/GLONASS: Accuracy and Availability Trials of a One-Chip Receiver in Obstructed Environments

December 1, 2011By

A one-chip multiconstellation GNSS receiver, now in volume production, has been tested in severe urban environments to demonstrate the benefits of multiconstellation operation in a consumer receiver. Bringing combined GPS/GLONASS from a few tens of thousands of surveying receivers to many millions of consumer units, starting with satnav personal navigation devices in 2011, followed by OEM car systems and mobile phones, significant shifts the marketplace. The confidence of millions of units in use and on offer should encourage manufacturers of frequency-specific components, such as antennas and SAW filters, to enter volume mode in terms of size and price. read more
