	[[GALILEO Search and Rescue Service\|GALILEO Support to Search and Rescue Service (SAR)]] represents the contribution of Europe to the international [http://www.cospas-sarsat.org COSPAS-SARSAT] co-operative effort on humanitarian Search and Rescue activities. Galileo ~~is to play an important part of the Medium Earth Orbit~~ Search and Rescue system (MEOSAR). Galileo satellites will be able to pick up signals from emergency beacons carried on ships, planes or persons and ultimately send these back to national rescue centres. From this, a rescue centre can know the precise location of an accident. At least one Galileo satellite will be in view of any point on Earth so near real-time distress alert is possible. In some cases, feedback could be sent back to a beacon, something which is only made possible by Galileo.<ref name="ESA_GALILEO">[http://www.esa.int/esaNA/galileo.html ESA Galileo web page]</ref>

	~~==The COSPAR-SARSAT Mission==~~
	The International [http://www.cospas-sarsat.org/ COSPAS-SARSAT] Programme provides accurate, timely, and reliable distress alert and location data to help search and rescue authorities assist persons in distress. The objective of the Cospas-Sarsat system is to reduce, as far as possible, delays in the provision of distress alerts to Search and Rescue (SAR) services, and the time required to locate a distress and provide assistance, which have a direct impact on the probability of survival of the person in distress at sea or on land.<ref name="COSPAS-SARSAT">[http://www.cospas-sarsat.org/ COSPAS-SARSAT web page]</ref>

	To achieve this objective, Cospas-Sarsat Participants implement, maintain, co-ordinate and operate a satellite system capable of detecting distress alert transmissions from radiobeacons that comply with Cospas-Sarsat specifications and performance standards, and of determining their position anywhere on the globe. The distress alert and location data is provided by Cospas-Sarsat Participants to the responsible SAR services.

	Cospas-Sarsat co-operates with the International Civil Aviation Organization, the International Maritime Organization, the International Telecommunication Union and other international organisations to ensure the compatibility of the Cospas-Sarsat distress alerting services with the needs, the standards and the applicable recommendations of the international community.

	~~==Galileo contribution (SAR/Galileo) ==~~
	~~[[File:helicopter_and_boat.jpg\|250px\|Galileo Search and Rescue Service\|right\|thumb]]~~

	The Galileo support to the Search and Rescue service - herein called SAR/Galileo -- represents the contribution of Europe to the international COSPAS-SARSAT cooperative effort on humanitarian Search and Rescue activities. SAR/Galileo shall: <ref name="GALHLD"> [http://ec.europa.eu/dgs/energy_transport/galileo/doc/galileo_hld_v3_23_09_02.pdf Galileo Mission High Level Definition], v3, September 2002.</ref>
	* Fulfil the requirements and regulations of the International Maritime Organization (IMO) - via the detection of Emergency Position Indicating Radio Beacons (EPIRBs) of the Global Maritime Distress Security Service ~~and of the International Civil Aviation Organisation (ICAO) via the detection of Emergency Location Terminals (ELTs)~~
	* Be backward compatible with the COSPAS-SARSAT system to efficiently contribute to this international Search and Rescue effort.

	~~SAR/Galileo will allow for important improvements of the existing COSPAS-SARSAT system:~~
	* near real-time reception of distress messages transmitted from anywhere on Earth (the average waiting time is currently one hour);
	* precise location of alerts (a few meters for EPIRBs and ELTs equipped with Galileo receivers, while the current specification for location accuracy is 5 km);
	* multiple satellite detection to avoid terrain blockage in severe conditions;
	* increased availability of the space segment (27 Medium Earth Orbit satellites on top of the four Low Earth Orbit satellites and the three Geostationary satellites in the current system).

	In addition, SAR/Galileo will introduce a new SAR function namely, the return link from the SAR operator to the distress emitting beacon, thereby facilitating the rescue operations and helping to identify and reject the false alerts. The service is being defined in cooperation with COSPAS-SARSAT, and its characteristics and operations are regulated under the auspices of IMO and ICAO. <ref name="ESA_GALILEO"/>

	~~==Performance and features==~~
	The Search and Rescue Transponder on Galileo satellites detects the distress alert from any COSPAS-SARSAT beacon emitting an alert in the 406 – 406.1 MHz band, and broadcasts this information to dedicated ground stations in the “L6” band. COSPAS-SARSAT Mission Control Centres (MCC) carry out the position determination of the distress alert emitting beacons, once they have been detected by the dedicated ground segment.

	The Service performances for the Galileo Search and Rescue Service are described in next table: <ref name="GALHLD"> [http://ec.europa.eu/dgs/energy_transport/galileo/doc/galileo_hld_v3_23_09_02.pdf Galileo Mission High Level Definition], v3, September 2002.</ref>

	The Search and Rescue (SAR) service of Galileo is also a key service for the safety of fishermen and sailors. Currently, in some situations of distress, several hours may be necessary to get the emergency beacon located by the emergency services. The future Galileo SAR service will be able to detect activated distress beacons and notify the appropriate rescue body almost in real time. Moreover, a return message will be sent to the emergency beacon, notifying the victims that their distress signal has been received and that help is on its way. In this context, the European Commission is a key actor to get Galileo SAR acknowledged by COSPAS SARSAT organisation.
