    dct:description "The Differential Deployable Autonomous Radio Navigation (ΔDARN) brings astronomical radio observations of quasars, masers and pulsars into play as a means to autonomously guide spacecraft among the planets, and even to the stars. The roadmap leads to a demonstration mission and utilization on deep space missions large and small. Phase 1 will produce a preliminary catalog of reference maser sources, a system analysis, and conceptual design of a demonstration mission." ;
