Space communication - Application of Software Defined Radio

Software defined radio can save cost of missions while constructing multiple mode, multiple band radio systems that can be upgraded using software. A common hardware is used for performing multiple functions through up gradation of software thus reducing the number of radios needed for a mission. If requirements change prior to the launch of an orbit, the software can be upgraded faster and easier than hardware. If an orbit fails, the software can be reconfigured. Thus, with minimal use of hardware, the total weight and cost of space hardware is reduced.
