The mission objectives are characterised by the determination of small height-related changes over a three-year period. This imposes requirements on the type of measurements to be made, the physical stability of the system, control of the measurement configuration and consistency in the data processing system. The programmatic constraints on the other hand, may be simply characterised as the need for a relatively short development cycle with a stringent cost ceiling. CryoSat is a fully integrated system in which all of the elements have been developed together within the programme to ensure the control needed to satisfy the mission objectives. However, in the interests of readability, the system's description has been split over two articles : this one describing the elements that are to be launched into space, and the following one those parts that will remain on Earth.
