The authors present three computer programs to compute geocentric tides including ocean and earth tides and ocean-loading effects along parallel satellite tracks from the harmonic ocean tidal constants listed on the NSWC GOTD Tape Schwiderski and Szeto 1981. The first program prepares a basic standard satellite track SST, which is shifted parallel to itself to define a 1 x 1 SST grid system. The second program computes harmonic geocentric tide data at all SST grid points, which are stored on three magnetic tapes SST GTD Tapes I, II, and III. From the prepared SST GTD tapes, the third SST program computes instantaneous tides along parallel satellite tracks by a smooth and fast inrepolation scheme. All three programs eliminate various input-error possibilities of their preliminary versions, which have been applied to compute instantaneous geocentirc tides along SEASAT tracks. The program descriptions include corresponding Users Guides and Program Listings. An extended version of the SST program is in preparation. It will include group beat effects on all major tidal components by frequency-wise neighboring minor tidal modes. Author
