Locating: Process of pin-pointing the location of a beacon or search object by homing or other means. Maritime Assistance Request Broadcast (MARB): A relay request for assistance made by Coast Guard units for vessels needing non-emergency assistance. Match: Determination that solutions from different satellite passes likely emanate from the same signal source. (Matched solutions are merged to produce composite solutions. Unmatched positions are designated "images".) MAYDAY: Spoken international distress signal, repeated three times. Mean Coverage Factor (Cm): The average of all coverage factors. Used to obtain Cumulative Probability of Detection. MEDEVAC: Evacuation of a person for medical reasons. MEDICO: Medical consultation. Exchange of medical information and recommended treatment for sick or injured persons where treatment cannot be administered directly by prescribing medical personnel. Merchant Ship Search and Rescue Manual (MERSAR): Published by the International Maritime Organization to guide masters of vessels at sea during emergency situations. Merge: Process of developing composite solutions by combining matched single pass (elemental) solutions. Meteorological Visibility: The maximum range at which a large object, such as land masses or mountains, can be seen. Also referred to as Meteorological Range. Glos-5

Military Assistance to Safety and Traffic (MAST): An Army and Air Force program to assist in serious civilian medical emergencies by providing transportation. Military Direct Access Radar Channel (M-DARC): Computerized radar tracking system operated by the 6521st Test Squadron at Edwards AFB, CA. Records primary and secondary radar data from 10 radar sensors located in south central California. Recorded data is retained for 30 days. Minimax Solution: A means of obtaining datum and drift error, when one or more drift variables cannot be accurately determined, by calculating a minimum and maximum drift. Mission Conclusion Stage: A period during a SAR incident when SAR facilities return to their regular location and prepare for another mission. Mission Control Center (MCC): Ground system element of COSPAS-SARSAT which receives data from Local User Terminals, exchanges information with other Mission Control Centers, and distributes alerts and other COSPAS-SARSAT information primarily within its associated service area. Narrow Band Direct Printing (NBDP): A single channel synchronous radiotelegraph system that uses a 7-unit code, 170 Hz frequency shift with a modulation rate of 100 baud. National Airspace System Computer (NAS computer): Terminology associated with ARTCC ATC tracking coputers. National SAR Plan (NSP): An interagency agreement providing a national plan for the coordination of SAR services to meet domestic needs and international commitments. National Track Analysis Program (NTAP): An FAA system for retrieval of computer-stored radar data to locate a missing aircraft's last position. NAVAREA Warning: Long-range warning broadcasts issued by an area coordinator of the World-Wide Navigational Warning Service for the associated area. Broadcast is made with sufficient power to cover the entire area for which the area coordinator is responsible. NAVTEX: Direct printing telegraphy system for transmission of navigation and meteorological warnings and urgent information to ships. Non-Beacon Alert: Alert determined to result from other than a beacon activation. On Scene: The search area or the actual distress site. On Scene Commander (OSC): Commander of an SRU assigned to coordinate SAR operations within a specified search area. Operations Center: Multi-mission Coast Guard Centers which may function
