The overall objective of the proposed programme of work is to develop an ad-hoc radio network product which is integrated into a satellite system for the purpose of emergency service use, disaster recovery and Government security applications, as well as for commercial application in mineral extraction and oil and gas industries to improve safety, efficiency and to aid the rescue of personnel following incidents and accidents.
This means that the system can provide a resilient network which is independent of terrestrial infrastructure. The aim is to make the system compatible with a wide range of satellite systems, i.e. to be modem agnostic, to maximise future sales potential.
The resulting system will be trialled using Ku-band satellites, but will also be designed to be compatible with future S-band satellites.
A key feature of the programme will be consultation with the user community to ensure that their requirements and needs are captured and, as far as is technically feasible and commercially attractive, incorporated into the first generation system developed under this programme of work.
The key issue is to design an affordable adhoc voice and data capability with satellite backhaul in situations where fixed infrastructure is not available.
Providing a communications infrastructure that can be used in the first hours and days after a natural or manmade disaster in collapsed buildings, underground and other areas where the existing communication systems do not provide coverage. Integration of several terrestrial ad-hoc networks via satellite to co-ordinate operations in a number of areas, even where users are located in several groupings spread over a large geographical region.
The system will comprise an adhoc radio network operating in the unlicensed 2.4GHz band and will provide interfacing to satellite communications via a custom IP gateway. The highly portable gateway, linked to a ruggedized laptop, will run the applications software and enable monitoring of radio traffic.
Cobham’s Ad-hoc Mesh Radio Over Satellite System (CAMROSS)
A key element of the system is the benefits of the inherent relay properties of the ad-hoc radio system will ensure reliable communication in a local area including areas deep inside buildings and underground where satellite communications cannot normally provide coverage.
The hardware and software developed under this programme will be certified for commercial use and based on the strength of the commercial justification may also be qualified for intrinsically safe or even Chemical Biological, Radiological and Nuclear (CBRN) environments.
System compatibility will be demonstrated with existing Cobham products which will offer: (a) situational awareness system (based on Battlehawk) which offer tracking of user location to aid operational co-ordination and safety of personnel (based on GPS) and (b) video transmission based on Co-Orthogonal Frequency Domain Modulation (COFDM) to aid command centre co-ordination of operations.
