6.2.5 The COSPAS-SARSAT System includes 36 LEOSAR LUT stations, 6 GEOSAR LUT stations
and 19 Mission Control Centers that provide real-time as well as global-mode coverage for the
Northern Hemisphere, while the Southern Hemisphere is presently served primarily by the global
mode. Additional LUTs and MCCs are planned for installation in the near future both in the
northern and southern hemispheres.
The addition of the GEOSAR Satellite system greatly improves the reaction time for a security
event. This satellite system has no Doppler capabilities at 406 MHz but will relay the distress
alert to any of the LUT stations. When there is GPS data included in the distress message this
will instantly tell SAR authorities where you are located at. Hence speeding up the reaction time
by not having to wait for one of the LEOSAR satellite’s to come around.
