Abstract
AbstractThe European satellite navigation system Galileo is a highly promising technology and offers communication capabilities that can be bridled to provide an enhanced Search‐and‐Rescue (SAR) service in combination with the system, currently in service, Cospas‐Sarsat. In order to enhance the process of retrieval during a rescue operation, this article proposes a Short Messaging Service (SMS) by utilizing the existing message formats and owes of the SAR service. Architectural building blocks which are particularly belonging to either Cospas‐Sarsat or Galileo are highlighted. A new simulation method for local 3D scenarios is presented, which combines detailed 3D environment models with ray tracing and event‐based protocol simulation. Results, both in a global and local 3D setup, reflect the performance indicators of the satellite systems from which the achievable service quality of SAR‐SMS is deduced. The necessity of Galileo/SAR for highly reliable and fast applications in emergency situations is shown and a minimum number of Galileo satellites carrying SAR payload is derived.
