Abstract : An oven controlled oscillator has been developed by QE.A in collaboration with the C.N.E.S. to equip beacons for the SARSAT project. The aim of this project is to speed up rescue operations by pinpointing targets through precise satellite observation. The means of location are: - on board equipment assuring reception and pre-processing of the collected data. - ground stations for processing data sent by satellite in real time to local security stations. - distress beacons at 406 MHz adapted to the space system. These beacons contain an ultra stable oscillator the characteristics of which condition the performance of the whole system. Improvements over other similar oscillators have been made with regard to size, power consumption, resistance against shock and vibration.
