SpectraTime Awarded 4 M Contract to Supply Rubidium Space
SpectraTime awarded 4 M contract to supply Rubidium Spaceclocks to the Indian Regional Navigational Satellite System
SpectraTime, a company of the Orolia group (NYSE Alternext Paris - FR0010501015 - ALORO), today announced the award of a contract valued at approximately 4 million to supply Rubidium Space Clocks to the Indian Regional Navigational Satellite System (IRNSS). With this new contract, SpectraTime confirms its position as the world- leading supplier of space atomic clocks and is on the way to having the largest number of atomic clocks in space on-board satellites.
SpectraTime atomic clocks: the heart of the system --The principle of navigation by satellite is based on the transmission of signals coming from at least four satellites, to the users. To get very precise location data, these signals must be perfectly synchronized.The extremely precise measurement of time on board each satellite, achieved through embarked atomic clocks, is thus a central condition for the positioning performance of the system. In the framework of the IRNSS program, each satellite will have four SpectraTime Rubidium atomic clocks on board to reach a stability of less than 10 billionths of a second per day. To give a point of comparison, our clocks are 10million times more precise than a watch made of quartz" , says Pascal Rochat, Chief Executive Officer of SpectraTime.

SpectraTime: the leading space atomic clocks supplier --With this new contract, awarded just 4 months after Giove-B the second experimental satellite of the European Global Navigation Satellite System Galileo, was successfully launched, SpectraTime strengthens its competitive positions on the fast-growing GNSS market : 'A worldwide satellite navigation constellation consists of 20 to 30 satellites, embarking each 3 to 4 atomic clocks. Within 5 years, we expect to have the largest number of space-borne atomic clocks than any other company." Underlines Pascal Rochat. 2008 Al Bawaba (www.albawaba.com)
