Temex is to supply its ultrastable crystal oscillator products to the German SAR-Lupe satellite reconnaissance project. The contract was awarded by the prime contractor to SAR-Lupe, OHB System, after a three-month evaluation involving four short-listed suppliers. "We were very pleased that Temex oscillators were found to be technically superior during the evaluation, and another key parameter in winning the contract was our ability to support OHB System in the system adaptation", said Damien Camut.

Key advantages of Temex' ultrastable OCXO technology included very good short-term stability at 1e-12/s and its low-profile package less than 30mm high.

Short-term stability is a prime requirement of many high performance systems including Doppler radar where short term stability is directly related to accuracy, radar imaging for maximum image resolution, and in positioning systems such as GPS and Galileo to enhance co-ordinate resolution and accuracy.

SAR-Lupe is a system of five satellites plus a ground segment, capable of operating in all weather conditions and during day or night to deliver up-to-date and highly detailed images from virtually all regions of the world.

The first satellite is scheduled for launch in 2005 aboard a Russian launcher, and the system will enter service in 2007.

OHB System, the prime contractor is leading a consortium of leading European space contractors.

Seeking the best available ultra stable crystal oscillators, OHB System sought tenders from well-known potential suppliers throughout Europe and the USA and selected Temex after rigorous evaluation of products and suppliers.
