LETVIS SAR is a control and information system for military and civil Search and Rescue (SAR) Centers. This system is designed for the control of search and rescue operations aimed at person recovery in case of aircraft accidents or in emergency states.

Operators are provided with information on current and planned civil/military air traffic, meteo data, aeronautical data, parameters of controlled flights, information on terrain clearance in search and rescue areas as well as on search operation progress. The system enables all the information to be analysed on real-time basis in order to effectively control not only the SAR helicopters but also local Ground-based SAR Teams.

The main mission of SAR centre is to coordinate the activities of the respective parts of SAR system with the aim of making their utilization in case of emergency. To achieve that, it is necessary to ensure perfect data and information exchange between the ground units and the aircraft – i.e. helicopter. The ground-based control centre has to receive the most precise information on the flight position of the helicopter during the entire operation and to keep up permanent communication. This is ensured by complementing the hybrid communication system by UMTC , or GPRS, VHF, as well as those of satellite communication system intended for data transfer, especially the information on the actual position of rescue means obtained via Global Positioning System (GPS).
