Mission Control Centre (Cospas-Sarsat)
Within the Cospas-Sarsat programme, ''Mission control centres (MCCs)'' are responsible for receiving and distributing distress signal alerts from emergency position-indicating radiobeacon stations. MCCs are a core component of the international satellite based search and rescue system. The functions of an MCC are: * to collect, store and sort the data from local user terminals (LUTs) and other MCCs; * to provide international and national data exchange within the Cospas-Sarsat system; and * to distribute alert and location data to associated rescue coordination centres (RCCs) or SAR points of contact (SPOCs) As of 13 May 2009, there are 29 MCCs around the world.

Distress Signal
A distress signal, also known as a distress call, is an internationally recognized means for obtaining help. Distress signals are communicated by transmitting radio signals, displaying a visually observable item or illumination, or making a sound audible from a distance. A distress signal indicates that a person or group of people, watercraft, aircraft, or other vehicle is threatened by a serious or imminent danger and requires immediate assistance.Aeronautical Information Manual U.S. Federal Aviation Administration, 2016 Use of distress signals in other circumstances may be against local or .

Emergency Position-indicating Radiobeacon Station
An emergency is an urgent, unexpected, and usually dangerous situation that poses an immediate risk to health, life, property, or Natural environment, environment and requires immediate action. Most emergencies require urgent intervention to prevent a worsening of the situation, although in some situations, mitigation may not be possible and agencies may only be able to offer palliative care for the aftermath. While some emergencies are self-evident (such as a natural disaster that threatens many lives), many smaller incidents require that an observer (or affected party) decide whether it qualifies as an emergency. The precise definition of an emergency, the agencies involved and the procedures used, vary by jurisdiction, and this is usually set by the government, whose agencies (emergency services) are responsible for emergency planning and management. Defining an emergency An incident, to be an emergency, conforms to one or more of the following, if it: * Poses an immediat ...

Ground Station
A ground station, Earth station, or Earth terminal is a terrestrial radio station designed for extraplanetary telecommunication with spacecraft (constituting part of the ground segment of the spacecraft system), or reception of radio waves from astronomical radio sources. Ground stations may be located either on the surface of the Earth, or in its atmosphere. Earth stations communicate with spacecraft by transmitting and receiving radio waves in the super high frequency (SHF) or extremely high frequency (EHF) bands (e.g. microwaves). When a ground station successfully transmits radio waves to a spacecraft (or vice versa), it establishes a telecommunications link. A principal telecommunications device of the ground station is the parabolic antenna. Ground stations may have either a fixed or itinerant position. Article 1 ยง III of the International Telecommunication Union (ITU) Radio Regulations describes various types of stationary and mobile ground stations, and their inte ...

Cospas-Sarsat
The International Cospas-Sarsat Programme is a satellite-aided search and rescue (SAR) initiative. It is organized as a treaty-based, nonprofit, intergovernmental, humanitarian cooperative of 45 nations and agencies (see infobox). It is dedicated to detecting and locating emergency locator radio beacons activated by persons, aircraft or vessels in distress, and forwarding this alert information to authorities that can take action for rescue. Member countries support the distribution of distress alerts using a constellation of around 65 satellites orbiting the Earth which carry transponders and signal processors capable of locating an emergency beacon anywhere on Earth transmitting on the Cospas-Sarsat frequency of 406 MHz. Distress alerts are detected, located and forwarded to over 200 countries and territories at no cost to beacon owners or the receiving government agencies. Cospas-Sarsat was conceived and initiated by Canada, France, the United States, and the forme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
