This paper presents investigations on a one year time series of cross-ing orbit differential interferometry SAR acquisitions with a 1-, 5-and 6-days temporal baseline. The conditions for crossing orbit in-terferometry are briefly discussed as the requirement of a common ground spectrum has to be satisfied. The uniquely short revisit times give the opportunity to perform interferometry on a glacier area, i.e. the Ronne ice-shelf, in X-band. The coherence results over one year as well as surface velocity measurements are shown and discussed.
