Abstract: Space Very Long Baseline Interferometry (SVLBI) is a technique in which an array of ground radio telescopes observes a source in conjunction with one or more orbiting radio telescopes. A synthesized aperture is produced with a diameter approximately equal to the apogee of the spacecraft orbit, enabling higher resolution imaging than is possible with ground-only VLBI. This paper discusses the characteristics and techniques of SVLBI, emphasizing the differences in capabilities and data-processing from traditional VLBI. General concepts are illustrated with a number of examples from the currently operational VLBI Space Observatory Programme, using a dedicated SVLBI satellite that was launched in February 1997. One technique used by the author is to perform amplitude
