Thales iCGRS Installed as Primary Reference Station Network in Saudi Arabia

Intergeo, Stuttgart, Germany (October 13, 2004) - Thales today announced that 14 of its Internet-enabled Continuous Geodetic Reference Stations (iCGRS™) reference stations fitted with choke ring antennas, and three Z-Max® survey systems were purchased by the Spatial Information System (S.I.S) Group in Saudi Arabia. These systems will enable the S.I.S. Group to install a reference station network in Saudi Arabia aimed at providing the most complete information possible for seismic research and other land management projects.

The resulting network is to be run by the Surveying and Mapping Department of the Ministry of Municipal & Rural Affairs (MOMRA), which is the national geodetic institute in Saudi Arabia. The goal is to install permanent reference stations in the Kingdom of Saudi Arabia.

With its Internet capabilities, iCGRS can be integrated with a Wide Area Network. Using DSL technology, the stations installed in the 13 provinces of Saudi Arabia will send raw GPS data files, recorded in one-second increments, every hour to a centralized server located in Riyadh. This server will format the data into RINEX and make it available on an ftp site to clients and users defined by MOMRA. This will be the CORS network of the Kingdom of Saudi Arabia and will provide the essential data needed for hundreds of projects related to the planning and developing of cities and villages, management of municipal services and lands, and rural cultivation and improvement.

Thales Z-Max survey systems will be used to survey 600 important topographical points in order to establish accurate geodesic markers, making this primary network denser and therefore more complete.

About iCGRS
The iCGRS system provides customers with direct Internet connectivity for the world's most powerful GPS reference station technology. As an enhanced version of the Micro Z-CGRS™, iCGRS is designed for high-accuracy applications and features an integrated Linux-based PC. Ideal as a permanent GPS base station with a direct connection to the Internet, a simple Web page interface enables users to remotely communicate with iCGRS.

The iCGRS system is designed to meet the stringent requirements of continuous unattended operation for the collection of high-quality, dual-frequency GPS data. Data files can be downloaded from the iCGRS while the receiver continues tracking and logging data, and data can be streamed in real time. External frequency input is standard. iCGRS eliminates the need to use an expensive, power hungry external PC to connect a reference station to the Internet.

Networks that rely on Thales reference stations include the U.S. and Canadian Coast Guards' Differential GPS network, Southern California Integrated GPS Network, National Geodetic Survey's CORS network, the Bay Area Regional Deformation network, the China Seismological Bureau, and the Shanghai Multi-Function Reference Network.

About Z-Max
The Z-Max is a precision GPS surveying solution designed for topography and construction. Offering superior RTK performance, an innovative design and a total software solution, Z-Max delivers survey-grade positioning on demand. Z-Max is capable of using VRS and FKP so that optimal results can be obtained in networks of reference stations.
