The purpose of this standard is to: ensure compatibility between ESA spacecraft TTC (Telemetry, Tracking and Command) transponders and the Range and Doppler Tracking (RDT) facilities of the ESA Earth network; define the compatibility between the agency's spacecraft and other networks with which they may have to work; establish a minimum level of RDT accuracy for missions conforming to this standard; facilitate the early design of flight hardware and ensure that the resulting project interfaces and system performances are compatible with given ESA ranging configurations and specifications. Direct ground to spacecraft ranging is concerned with single access RDT on direct links between spacecraft of category A or category B missions and Earth based stations. This volume is applicable to all ESA spacecraft that are supported for RDT by direct links to ESA-controlled Earth stations operating in the space operations service. Missions that are supported via Data Relay Systems (DRS) and that need, for backup support, direct links to ESA controlled ground stations are not necessarily bound by the requirements set out in this volume of the standard.
