Abstract: | This paper compares the requirements that can be expected of gravity measuring missions with respect to the status of the
instrumentation and satellite technologies. The error sources of gravity gradiometry and satellite-to-satellite tracking are
analysed and the elements limiting the accuracy are identified. Proposed and approved future missions that will fly technologies
of interest for gravity sensing are recalled. Areas of technical development of interest are reviewed. The article finishes
with two possible conceptual missions presented as examples and with a chapter of conclusions.
