| Abstract: | COSPAS-SARSAT provides free distress alert services to marine, aerospace and terrestrial users. According to the latest progress of COSPAS-SARSAT implementation plan for medium earth orbit satellite search and rescue,the return link service of other global navigation satellite systems will be introduced. The return link service will serve as an advanced function to realize alarm confirmation and two-way search and rescue information for distressed personnel, enhancing the survival confidence. Based on the characteristics of? BeiDou Satellite Navigation System(BDS), the development and application of return link technology of? BDS MEOSAR are discussed. |
