Combat SAR (CSAR)

The military customer also needs the capability

to rescue personnel in a combat situation with

the aid of a Combat SAR system. The Cobham

935 DF System combined with the latest

Personal Locator System (PLS) interrogator

provides a full CSAR capability. The system

has the capability to operate with Personnel

Survival Radios (PSR), such as the AN/PRC-112

and PRC-434 to provide range, bearing and ID

information. In addition, these systems can

provide the bearing co-ordinates from

an imbedded GPS in the URX3000 PSR.

The solution:Cobham DF systems are tailored to suit various

Search and Rescue requirements including DF

antennas for use with existing radios and up to

fully integrated multi-receiver solutions.

Directions Finding (DF) Systems for all

Search & Rescue (SAR) Missions

SAR Requirements

The ability to locate personnel in distress in all

theatres needs to be quickly and accurately

executed to maximise rescue success whatever

the prevailing conditions.

Aircraft or ships transmitting on the emergency

distress frequencies depend upon Homing/

Direction Finding (DF) equipment onboard

aircraft to guide the Search & Rescue crews.

Traditionally Homing systems have been used

to steer the rescue vehicle to the distress

source when it is within 30-40NM.

With the advent of the COSPAS-SARSAT 406MHz

service the satellite monitored distress beacon

signal now identifies the craft position and type.

Once decoded by the SAR aircraft equipment,

the signal can be used to augment the beacon

transmission to direct the rescue craft.

The Cobham range of DF equipment utilises

the latest multi-receiver technology and is

designed for both military and civil use. This

single box solution is also fully COSPAS-SARSAT

compliant and compatible with the

requirements of the Global Maritime

Distress and Safety System (GMDSS).

Beacons

Emergency Beacons come in several forms,

Emergency Locator Transmitters (ELT), Personal

Locator Beacon (PLB), Emergency Position

Indicator Radio Beacon (EPIRB), Personal

Emergency Location System (PELS) and Auto

Emergency Locator Beacons (ADELT).

Cobham manufactures a complete range of

Emergency Beacons. All of these Beacons are

fully compatible with the new SAR Homing and

DF Systems.

Typical SAR operation involving US Coast Guard.

935 Series

The 935 Series of tactical Direction Finders

provide a range of integrated DF solutions

for bus-controlled and stand-alone direction

finding systems. 935 DFs include an integral

synthesised receiver covering the frequency

range 30-470MHz together with five Guard

receivers to monitor pre-defined distress

frequencies. Bearings may be taken on all six

receivers simultaneously. Data decoding is

provided for COSPAS-SARSAT messages and

for marine DSC messages on the associated

Guard receivers.

1 935 DF plus 715-40 controller. 2 931/933 Series plus 7-26-39 controller. 3 7-23-30 DF plus 400-047992 remote

control and display unit.

931/933 Series

The 931 and 933 Series Direction Finding

antennas are configured to operate

with external radios. Cobham Antenna

Systems provide a range of small-profile

Guard receivers to monitor the standard

international distress frequencies. Bearing

display is accomplished via serial interfaces

including ARINC429, ARINC407 and RS422.

Control is accomplished via a bus controller

or via a dedicated Cobham Antenna System

controller such as the 7-26-39. The 933 Series

permit control via ARINC429.

System 7

The System 7 Direction Finder forms part of a

small-size, stand alone, direction finding solution

designed to provide a DF capability on the

VHF and UHF distress frequencies. With two

integrated receivers, two frequencies can be

monitored simultaneously obviating the need

for an external receiver. The System 7 only

requires a remote control and display unit to

provide a complete system supplying relative

bearing information and additionally provides

an ARINC429 output of bearing and associated

receiver frequency. The system is also COSPAS-

SARSAT capable.
