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.
