SpectraTime has announced its receipt of a contract valued at approximately €4 million to supply rubidium space clocks for the Indian Regional Navigational Satellite System (IRNSS), a GNSS system that is under development by the Indian Space Research Organization (ISRO).

The IRNSS will consist of seven satellites, three in geostationary orbit and the other four in geosynchronous orbit. First launch of an IRNSS is currently expected in 2009. The system will transmit BOC(5,2) and BPSK signals at the L5 frequency (1176.45 MHz) and also in S-band.

Headquartered in Neuchatel, Switzerland, SpectraTime is part of the Orolia group of companies and has provided atomic clocks for Europe’s Galileo and China’s Compass GNSS systems.

Within 5 years, the company expects to have more spaceborne atomic clocks in orbit than any other company, according to Pascal Rochat, SpectraTime’s CEO.
