Side-Looking Airborne Radar (SLAR): Aircraft-mounted radar designed to
detect targets on or near the ocean surface by transmitting signals
perpendicular to the aircraft flight track. Signal coverage of an area
is achieved by aircraft motion alone, without antenna rotation.
Single Pass: Portion of a satellite orbit during which it is within view
of a given position.
Single Pass Position: Position obtained from a single pass solution.
Single Pass Solution: One of two positions equidistant on each side of a
ground track, one position corresponding to a real location and the
other being its image, computed using doppler data from a single pass,
sometimes referred to informally as a "single hit".
Site: Position identified by a site ID.
Site ID: Alphanumeric code assigned to each single pass solution. For
beacons operating on 121.5 and 243 MHz, the code gives frequency,
specifies whether the solution is an "A" or a "B" solution, and assigns
a sequential solution number; for 406 MHz beacons, the site ID is the
beacon ID.
Situation Report (SITREP): Reports, from the OSC to the SMC or the SMC
to interested agencies, to keep informed of on scene conditions and
mission progress.
Small Boats: Coast Guard marine SRUs under 65 feet in length.
Solution: Position determined by COSPAS-SARSAT ground processing using
doppler data.
Sortie: Individual movement of a resource in rendering assistance.
Speed of Advance: Speed a surface vessel is making relative to the
earth's surface.
Spurious Solutions: Solutions generated due to causes other than beacon
signals.
