Abstract: Disclosed an apparatus and method of partitioning compressed satellite image, and more specifically, the present invention relates to a technique for forming index information on the compressed satellite image using the starting point and the length of a compressed section so as to randomly access each compressed section in the wavelet-based compressed satellite image recommended through CCSDS. The present invention minimizes costs for long-term storage of the satellite image data by immediately indexing, partitioning, and storing the compressed satellite data in a storage without recovering the compressed satellite data, rapidly provides high-quality satellite images for users by minimizing information loss while recovering the compressed image, and thereby being effective for being able to reduce computing resources needed to recover the compressed image data.

Abstract: An absolute gravity inline measuring apparatus includes an interferometer arrangement, a test mass tracking system, and a superspring mechanism. The interferometer arrangement includes first and second beam splitters for respective splitting and recombining a laser light beam and upper and lower cornercube retroreflectors facing toward one another and spaced above and below the first beam splitter so as to reflect one split portion of the laser beam in vertically-aligned upper gravity measuring and lower motion compensating portions of a variable leg of the interferometer light beam path. The test mass tracking system includes a cart vertically movably in an evacuated elongated housing and releasably supporting a test mass in a drag-free enclosure. The test mass incorporates the upper retroreflector of the variable leg of the interferometer light beam path.
