User equipment for LEO spacecraft positioning using NAVSAT and GPS is defined, and a development approach is outlined. It is concluded that both systems are cost effective. When the high performance P-Code receiver is required, the implementation of existing U.S. equipment in collaboration with American firms is recommended. This offers lower risks and lower investment by European resources, compared to a full European development. For applications where C/A code receivers can be used a study phase is recommended in order to define and evaluate the required changes over the existing European C/A receiver developments to decide upon the suitability of the modified receivers for space applications. Regarding Columbus as a candidate to carry a GPS receiver, simulations and ground tests are recommended in favor of an earlier experimental mission. Columbus would be very costly and the feasibility of using GPS as a spacecraft navigation system is already established in experimental missions.
