By Sandra Verhagen High-precision Global Navigation Satellite System (GNSS) positioning results are obtained with carrier phase measurements, once the integer cycle ambiguities have been successfully...
Experts representing the Galileo Program provided a frank and open update on how it is addressing the problem of the first two full operational capability (FOC) satellites being delivered to the...
By Saeed Daneshmand, Ali Jafarnia-Jahromi, Ali Broumandan, and Gérard Lachapelle Most anti-spoofing techniques are computationally complicated or limited to a specific spoofing scenario. A new...
By Inder Jeet Gupta It is well known that the phase center of a GNSS antenna can vary with the satellite direction. This phase center movement leads to aspect dependent carrier phase and code phase...
A panorama from the GNSS tide gauge at Onsala Space Observatory. When satellites pass over the sky, the GNSS tide gauge uses signals direct from the satellite and signals reflected off the sea...

Rohde & Schwarz has added the R&S RTM-K18 spectrum analysis and spectrogram option to its R&S RTM oscilloscope family, making the R&S RTM the only oscilloscope in its...
GNSS simulation expert Spirent Federal is inviting users to “a rigorous and thorough” one-and-a-half-day training conference, including a half-day of For Official Use Only (FOUO)...
Enhancing GNSS Receiver Sensitivity by Combining Signals from Multiple Satellites By Penina Axelrad, James Donna, Megan Mitchell, and Shan Mohiuddin A new approach to enhancing signal sensitivity...
The GSG-51 GNSS signal generator provides a fast and cost-effective solution for production testing for Galileo and other GNSS. It emulates a single GNSS signal and can be upgraded for Galileo, as...
The Galileo Test and Development Environment (GATE) in Berchtesgaden, Germany, officially opened on February 4. The system operator, IFEN GmbH of Poing, Germany, jointly with the German...
Averna, developer of test solutions and services for communications and electronics device makers, announces the availability of a field-ready multi-channel RF Recorder for RF applications covering...
Spirent Communications today announced the launch of its new GSS6300M Multi-GNSS simulator designed for integration, verification, and production testing where a quick and accurate functional test is...
Using Microwaves and Laser Ranging for Precise Orbit Determination By Erik Schönemann, Tim A. Springer, Michiel Otten, and Matthias Becker Though Galileo’s GIOVE-A is a test satellite not...
The U.S. Department of Transportation will host a third workshop to continue discussions of the GPS Adjacent Band Compatibility Assessment on March 12. The workshop will focus on the following...
A performance assessment demonstrates the ability of a networked group of users to locate themselves and each other, navigate, and operate under adverse conditions in which an individual user would...
By Wei Liu, Xingqun Zhan, Li Liu, and Mancang Niu A comprehensive methodology combines spectral-separation and code-tracking spectral-sensitivity coefficients to analyze interference among GPS,...
Galileo, that’s who! For dogged determination and persistent pushing-forwardness in the face of adversity, obstacles, and the occasional technical difficulty. That there may be occasional...
In November, December, and January, a regulatory drama with high potential impact on the GPS signal and domestic U.S. GPS users began unfolding before the Federal Communications Commission (FCC). As...
One of two Galileo satellites, safely in its protective container, is unloaded from an Air France Boeing 747 at Cayenne–Félix Eboué Airport in French Guiana. News from the European Space Agency...
