Combat Survivor Evader Locator (CSEL)


Worldwide, secure over-the-horizon communication for isolated personnel is available now!

CSEL Chart The Combat Survivor Evader Locator (CSEL) is the U.S. Department of Defense (DoD) Program of Record for Joint Search and Rescue. This fully qualified, next-generation survival radio system is comprised of over-the-horizon relays, ground, and user equipment segments for the joint services. Today, CSEL is providing global coverage for U.S. DoD forces world wide.

CSEL minimizes the search aspect of a rescue mission by providing recovery forces with precise geo-positioning information and secure, over-the-horizon and line-of-sight, two-way data communications capabilities. These capabilities enable Joint Personnel Recovery Centers (JPRCs) and recovery forces to locate, authenticate, and communicate with Isolated Personnel (IP) in near real-time, anywhere in the world.

CSEL has undergone extensive government field testing and successfully completed a Multi-service Operational Test and Evaluation phase. In December 2005, CSEL received authorization for use in theater by the United States Central Command.

The CSEL program is in full-rate production; delivering units monthly. All segments of the CSEL system are developed, maintained, and upgraded by Boeing, under contract to the U.S. Air Force (joint program lead agency). The system is operated and managed by the Joint Program Office for Personnel Recovery at the Electronic Systems Center, Hanscom AFB, Mass.

CSEL addresses the need for an improved survivor/evader recovery system

The need for an improved Combat Search and Rescue (CSAR) capability grew out of deficiencies identified during operations in Southwest Asia and Bosnia when rescue missions experienced an extremely low recovery rate and often exposed the rescue forces to very high enemy threats.

CSEL is a revolutionary improvement in combat search and rescue

Current survival radios are only effective if friendly forces are within line-of-sight (LOS) and offer very little to counter the possibility of enemy intercept or jamming. The CSEL system overcomes these limitations by providing a revolutionary solution for combat search and rescue communications. It is based on a flexible, modular communication architecture over multiple satellite links for dependable, secure satellite communications, line-of-sight voice communications, global position, navigation and beacon functions. Rescue mission command and control is provided over a robust, worldwide C4I system that is fully integrated into the Global Command and Control System.

CSEL greatly increases the probability of search and rescue mission success

When activated by the Isolated Person (IP), the CSEL handheld radio automatically and securely transmits their exact GPS location and identification information. The IP and Rescue Centers are able to exchange messages on the IP's physical condition, enemy location, rescue plans, and more. With this information, the rescue forces can plan and execute the mission while minimizing the danger to the IP and rescue personnel. CSEL makes "first pass" rescues a reality.
