The ability to perform radio functions in the software domain enables cheaper, more reliable and highly flexible systems to be developed. This is important in the space segment, where the expected life of the equipment is long and the ability to configure and upgrade the radio to implement additional features and requirements after deployment is highly desirable. The more of the design that can be made “softâ€, the greater the ability to re-use technology and capitalise on previous investment.

The work of the Satellite Communication Network of Excellence (SatNEx) initially supported by the European Union (EU) is continuing with support from ESA´s TIA Directorate through the Advanced Research in Telecommuncations Programme (ARTES) and the Technical Directorate Network of Centers programmes. Due to this shift in support, the name of the group has changed slightly to the Satellite Communication Network of Experts.
The overall objective of the proposed 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. It can also be used 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.
Altobridge´s 3G lite-site (DATE) solution offers bandwidth hungry 3G services to remote communities. The current 2.5G altoPod provides 2TRX capacity which is capable of voice and GPRS/EDGE. The 3G lite-site is a natural evolution of the solution into 3G technology.
The objective of the study has been to brainstorm potential communication satellite standardized modules and to derive a solution which allows to save manpower and costs for non-recurring and recurring satellite design. It also aimed to shorten the AIT process, giving an estimation of the relative high non-recurring costs for the design and prototyping of the standardised modules.
