[Termes IGN] positionnement par GNSSRésumé : (Auteur) A new version of the Receiver Independent Exchange (RINEX) format (version 3.0) for Global Navigation Satellite System (GNSS) observation data has been proposed by Gurtner and Estey (2006) to accommodate recent progress in the GNSS environment such as modernization of the Global Positioning System (GPS) and the emergence of new GNSS systems. The compact RINEX format version 3.0 has been developed to compress files in this format by adjusting the existing old compression format for RINEX version 2.xx. The compression rate, combined with the additional text compression, is about 38% of that with the simple application of text compression. The compression / decompression of both old and new formats can be performed seamlessly with the same tools and the same usage. The format and tools will contribute to the popularization of RINEX format version 3.00 and, through this, facilitate the exchange and use of GNSS data.

[Termes IGN] temps réelRésumé : (Auteur) The GPS Earth Observation Network system (GEONET) has been playing an important role in monitoring the crustal deformation of Japan. Since its start of operation, the requirements for accuracy and timeliness have become higher and higher. On the other hand, recent broadband communication infrastructure has had capability to realize real-time crust monitoring and to aid the development of a location-based service. In early 2003, the Geographical Survey Institute (GSI) upgraded the GEONET system to meet new requirements. The number of stations became 1200 in total by March, 2003. The antennas were unified to the choke ring antennas of Dome Margolin T-type and the receivers were replaced with new ones that are capable of real-time observation and data transfer. The new system uses IP-connection through IP-VPN (Internet Protocol Virtual Private Network) for data transfer, which is provided by communication companies. The Data Processing System, which manages the observation data and analyses in GEONET, has 7 units. GEONET carries out three kinds of routine analyses and an analysis of RTK-type for emergencies. The new system has shown its capability for real-time crust monitoring, for example, the precise and rapid detection of coseismic (and post-seismic) motion caused by 2003 Tokachi-Oki earthquake.
