JERNAS was a variant of the UK Rapier FSC developed by MBDA for export. It is an all-weather mobile point-defence system designed to counter low altitude airborne threats including UAVs, cruise missiles, and fixed/rotary wing aircraft. It is currently in service with both the British Army and Malaysian Army.
Cunning Running Software was sub-contracted by MBDA to integrate ADSC (the Air Defence Siting Computer) with the Network Remote Display Unit (NRDU) so that threats and weapon locations could be viewed and optimised in real time using Local Air Picture track data from Surveillance Radars. A close working relationship with the Malaysian Army
Military Survey organisation was necessary to incorporate their mapping formats into ADSC and NRDU.
