A satellite based localisation service using a 3G mobile phone as an emergency terminal

Abstract

In this paper, a new satellite based search and rescue system is designed. The old one -the COSPAS-SARSAT distress alert detection and distribution system, has been working for 30 years and rescued about 40 thousands of lives world-wide, in spite of low precision of the distress localization and long localization time. In this paper, a new system is designed, whose user terminal can be implemented into a 3G mobile phone, without increasing its size and power, while using a Global Navigation Satellite Systems (GNSS) like GPS, GLONASS or Galileo. The system will offer an exact and quick location service also in areas without the terrestrial mobile network coverage for billions of 3G users.

Design of a Baseband Signal for the 406 MHz Satellite Emergency Radio Transmitter Based on STM32

“…The COSPAS-SARSAT system [1,2], which consists of space segment and ground segment, provides a distress alert and the position information for a distressed ship or person with beacon equipment [3][4][5][6]. The second generation 406 MHz beacon allows for the coding of position data in the transmitted 406 MHz message, thus providing for quasi-real time alerts and position information from the GEOSAR system [7,8].…”
