- Abstract
- This paper presents a novel power control scheme for second generation beacon in COSPAS-SARSAT system. COSPAS-SARSAT system which consists of space segment and ground segment provides a distress alert and the position information for a distressed ship or airplane with beacon equipment. In a distress situation, the beacon transmits the distress signal by predetermined transmission power after beacon activation, and also requires the operating life-time of 24 hours or more. Because implementation of enhanced performance and operating life-time is a trade-off relationship, it is necessary to adjust properly in order to improve performance. Thus, enhanced detection of satellite and long operating life-time of beacon may be achieved by repetition rate or power of the transmitted signal.
