Applications of GNSS in West Africa

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
The applications of GNSS in West Africa are enhanced by the objectives of the African Geodetic Reference Frame (AFREF) which is to establish an unified reference frame through the use of Space Geodesy Techniques, GNSS in particular, to tie various national and regional reference networks of Africa.

Time-Frequency Excision for GNSS Applications

IEEE Systems Journal, 2008
Interference detection and mitigation in global navigation satellite systems (GNSSs) are important issues for both military and civilian applications. In this paper, a novel time-frequency algorithm for GNSS application is proposed. The use of infinite impulse-response notch filters for the interference excision is introduced and analytical formulas ...

Dynamic GNSS Testing and Applications

2009 Reno, Nevada, June 21 - June 24, 2009, 2009
Satellite-based global navigation systems are a ubiquitous component in modern guidance systems. Automated guidance in agricultural vehicles is a prime example of how Global Navigation Satellite System (GNSS) receivers can be applied to operations requiring a level or precision, or consistency, which may otherwise be unobtainable.

GNSS vulnerabilities and vehicle applications

2016 13th Workshop on Positioning, Navigation and Communications (WPNC), 2016
The progress of vehicle-automation requires vehicle location with higher accuracy, shorter time-delay, and higher time-resolution, furthermore, many safety connected-vehicle applications, for example, crash-warning with vehicle-to-vehicle communication require more accurate time-stamps on the data from individual vehicles.

An Application for Detecting GNSS Jamming and Spoofing

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2021
Global Navigation Satellite System (GNSS) location engines on Android devices provide incredible location and navigation utility to billions of people worldwide. However, these location engines currently have little to no protection from accidental or intentional tampering that could block service or even spoof the reported location.

Specification of GNSS application for multiprocessor platform

2008 International Symposium on System-on-Chip, 2008
In this paper we present a satellite navigation application for a multiprocessor platform. We give a preliminary description to the multiprocessor platform with an introduction to the project where it will be designed and implemented to a fabric die. The platform contains a matrix of processing tiles, connected together via a Network-on-Chip.

The ACES GNSS subsystem and its applications

EFTF-2010 24th European Frequency and Time Forum, 2010
The ESA mission Atomic Clock Ensemble in Space (ACES) will operate a new generation of atomic clocks on board the International Space Station (ISS) in 2013-2015 timeframe. The ACES payload will be attached externally to the European Columbus module. The ACES clock signal will reach fractional frequency stability and accuracy of 1 part in 10-16.
