JP 3-50 National Search and Rescue Manual Vol I - US Navy

Confidence Factor (CF): Value, normally 0.3, applied to account for
errors in assumed initial distress position, sea current, wind current,
and leeway. Used to determine drift error (de).
Confidence Factor (COSPAS-SARSAT): International measure of estimated
solution accuracy as follows:
Precision (NM): < 5 < 20 < 50 > 50
Common Description: Good Medium Poor
ICAO/ITU Class: A B C D
Continuous Data Recording (CDR): Data extraction terminology associated
with FAA ARTSIII/IIIA and E-ARTS tracking systems.
Coordinated Search Pattern: Multiunit pattern using vessel(s) and
aircraft.
Coordinator Surface Search (CSS): A vessel, other than an SRU,
designated to coordinate surface SAR operations within a specified
search area.
Core Frequency: Estimate of the primary frequency of a signal detected
by COSPAS-SARSAT.
Coriolis Force: The effect of earth rotation upon wind-driven currents.
COSPAS: Cosmicheskaya Sistyema Poiska Avariynych Sudov - Space System
for Search of Distressed Vessels. U.S.S.R. segment of COSPAS-SARSAT
satellite system. See Search and Rescue Satellite-Aided Tracking.
Country of Registration: Country identified in coding of a 406 MHz
beacon.
Course: The intended horizontal direction of travel of a craft.
Coverage Factor (C):
1. A measure of search effectiveness or quality.
2. Intermediate calculation when developing Probability of
Detection (POD).
