And they still are. More than half a century has passed since the launch of the first artificial satellite in October 1957. Currently, more than a thousand active satellites — both government and privately owned— are orbiting around us. The data and signals provided by these devices have become essential for many of our everyday activities. European investments in EGNOS, Galileo and Copernicus16 ― EU space flagship programmes ― clearly indicate the strategic role played by satellite-based services in achieving safety, growth and sustainability. Indeed, despite the economic crisis, the European Union (EU) allocated around €6.3 billion to Galileo, the European satellite navigation system, and 4.3 billion to the European Earth observation system GMES-Copernicus for the period 2014-2020. The Horizon 2020 EU Research and Innovation programme also dedicates a further 1.73 billion to space research and development. Meanwhile, the European Space Agency alone is investing €309.2 million, i.e. 7% of its 4.4 billion budget for 2015-18, in telecommunications and integrated applications to support the development of market-oriented spacebased services. In 2015, ESA is also investing €1.25 billion on Earth observation and 664 million on satellite navigation-related activities. [...] Note de contenu : Introduction The survey Results of analysis 1.

GPS-Anwendungen in der Sportwissenschaft / T. Blumenbach (2005)

First investigations are accomplished in sports sciences as well. However, most geodetic GPS equipment is too large and too heavy for attaching it at the athletes body. Using the potential of miniaturized electronics, a special GPS receiver for ski jumping was developed. The hardware could be integrated completely into a common jumping helmet. Striving to an ideal measurement system with no influence on the athlete activities only little adverse effects remain on the athletes using the GPS-helmet. The topography of jumping hills results in a more or less shadowing of the GPS satellite signals. Not all jumping hills are applicable for GPS measurements. Measurement campaigns need to be well planned considering satellite constellation issues. Centimeter accuracy requires successful integer ambiguity fixing. Common algorithms assume uninterrupted signal reception over a sufficient long time. But the 10-20 seconds for an attempt, take-off, flight and landing are not long enough. Thus a laser light barrier array was developed. It determines position and time of the GPS-helmet during athletes take-off from the ramp. This information enables the ambiguity fixing and enhances accuracy and reliability of the solution, even for short GPS measurement segments. The system was successfully tested during some training sessions of german ski jumpers. It was shown which informations can be derived from positions and velocities for several phases of a jump.

GPS measurements in the Australian and Indonesian regions (1989 - 1993) / Paul Tregoning (1996)

There is an island, Christmas Island, located on the Australian plate about 150 km South of the subduction zone. Global Positioning System (GPS) measurements across the Java Trench were made between Christmas Island and West Java during five annual surveys commencing in 1989. This single baseline study was expanded in 1992 to include the Cocos Islands, located about 900 km Westsouthwest of Christmas Island, and a five station network spanning the Sunda Strait and the Southeastern end of the Central Sumatra Fault. The data processed in this thesis is a subset of a much larger crustal deformation study encompassing most of Indonesia. In addition, the deformation surveys were supported by GPS measurements from a global fiducial tracking network which included some stations on the Australian plate. The GPS data was processed using GAMIT/GLOBK software to determine GPS derived station velocities and relative motions across the plate boundaries. Daily GPS solutions were computed, with global orbits being estimated using the available fiducial tracking data. The global data was quite sparse prior to 1992 and hence was incorporated in the regional solutions. With the introduction of the International GPS Service for Geodynamics (IGS) in 1992 the number of fiducial tracking stations increased significantly. It was decided to use a combination approach whereby the regional and global data was processed separately in GAMIT and then combined in GLOBK.[...] Note de contenu : bibliographie Numéro de notice : 15976 Affiliation des auteurs : non IGN Thématique : POSITIONNEMENT Nature : Monographie Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=82423
