Abstract :
The European Galileo Plan will include the Search and Rescue (SAR) transponder. As a part of the future MEOSAR (Medium Earth Orbit Search and Rescue) system, the new SAR system can improve locating performance by estimating the FOA (Frequency of Arrival) and the TOA (Time of Arrival) of beacon signals. To meet the requirements of the SAR/Galileo system, the estimating error of TOA algorithm must be less than 7us. According to the features of the signal, we propose a novel TOA algorithm (called TPD algorithm). The simulation results show that TPD can satisfy the system´s requirement.
