Features/Capabilities
CSEL includes:
- a
multifunction, hand-held radio offering unique communication and
message encryption, which prevents signals from being intercepted, and
battery life providing crucial contact for extended periods.
- secure
digital message communications, Global Positioning System (GPS),
line-of sight (LOS) voice and the full spectrum of radio and ground
equipment interfaces required to work with existing search and rescue
(SAR) systems.
Providing a complete system solution, the CSEL communication systems is made up of a user equipment segment, ground segment, and OTH relay segment.
The User Equipment
segment consists of a multifunctional hand-held radio and theater
mission planning computers, including GPS key loaders. The hand-held
radio supports data communication for all OTH Relay modes:
- aircraft interrogation
- precise geopositioning
- SAR aircraft-compatible line-of-site (LOS) voice and beacon
The Ground
segment is designed to operate simultaneously with other government
systems. It uses existing infrastructure providing a highly reliable
and timely global connection between all CSEL ground elements:
- hosted on existing government networks and workstations
- user friendly interface
- extensive mapping capability
The OTH Relay
segment uses multiple, and in most cases, redundant DoD communication
channels to assure transmission and reception of CSEL message traffic,
resulting in rapid CSAR response times. It provides:
- near real-time two-way secure messaging and geolocation
- multiple satellite links
- extensive use of commercial off-the-shelf/government off-the-shelf (COTS/GOTS) hardware for base station
The
CSEL architecture meets near-term requirements, while assuring
flexibility for future growth, and enhancements, including migration to
a commercial satellite solution.
