[Termes IGN] utilisateur civilRésumé : (Auteur) Many civil GNSS applications need secure, assured information for asset tracking, fleet management and the like. But there is also a growing demand for geosecurity location-based services such as hardware configuration and management, virtual site licenses, digital rights management and geofencing. Unfortunately, GNSS is vulnerable to malicious intrusion and spoofing. How can users be sure the information they receive is authentic? This article introduces a new method that uses hidden attributes fundamental to the GPS satellite broadcast — and cross-compared between two receivers — to authenticate signals and the location solutions they generate.

[Termes IGN] tempête magnétiqueRésumé : (Auteur) The approaching solar maximum will produce magnetic storms, ionospheric storms, and disruptions to radio signals that directly affect the world’s technical infrastructure, including GNSS. The authors propose a method for evaluating the ability of GPS receivers to operate through scintillation before the next solar maximum arrives in 2013.

[Termes IGN] télémétrie laser sur satelliteRésumé : (Auteur) We use them for listening to music, for routine surgeries, for making a point in a presentation, and even for hanging pictures straight. Of course, I'm talking about lasers. Invented in 1960, the laser (an acronym for light amplification by the stimulated emission of radiation) has become ubiquitous in modem society. Every CD and DVD player has one. Many printers use them. But lasers are also used in a wide range of industrial and scientific applications including determining the orbits of satellites through satellite laser ranging (SLR). In the SLR technique, pulses of laser light from a ground reference station are directed at satellites equipped with an array of coner-cube retroreflectors, which direct the pulses back towards a collocated receiving, telescope. By accurately measuring the two-way travel times of the pulses and knowing location of the station and other operating parameters, the positions of the satellites can be determined. A network of SLR reference stations around the globe is used to monitor the orbits of satellites over time and their variations have been used by scientists to improve our knowledge of the Earth's gravity field ; to study the long term dynamics of the solid Earth, oceans, and atmosphere; and even to verify predictions of the General Theory of Relativity. The first SLR measurements were obtained from the Beacon Explorer-B satellite which launched in october 1964. Since then, dozens of satellite equipped with corner-cube retroreflectors have been launched including a number of radio-navigation satellites. Every GLONASS satellite is equipped with retroreflectors and two GPS satellite have been equipped - SVN35/PRN05 and SVN36/PNR06. The COMPASS-M1 satellite in medium earth orbit carries retroreflectors, as do both GIOVE-A and -B, the Galileo test satellites. Precise orbit determination of radio-navigation satellites using SLR has the advantage of being unaffected by any onboard satellite electronics and associated signal biases. Radiometric observations of a satellite's microwave signals, on the other hand, are influenced by the satellite's clock, for example, and its effect must be estimated to obtain precise (and accurate) satellite orbits for navigation and positioning. Therefore, a comparison of SLR-and microwave derived orbits can be very useful for studying the performance of the data measurement and orbit-determination processes of both techniques. In this month's column, we take a look at some work being carried out to precisely determine the orbit of the GIOVE-A test satellite using SLR and microwave observations. This preliminary investigation will benefit the procedures to be implemented for the future Galileo constellation.

[Termes IGN] signal GPSRésumé : (Auteur) This month we bring you an extended interview with engineer Perdo Pedreira, executive director of the European Global Navigation Satellite System Supervisory Authority (GSA). Since July 2005, the body charged with managing the development phase of the much-troubled European Satellite navigation system Galileo, its anticipated economic benefits, in terms of revenue, employment and expanding markets, are many. Galileo is being funded by the EU taxpayer, so it is important that these benefits be realised.
