This new DoD and NASA created the new realize-on National Geodetic Satellite System (NGSP) in 1964 (Document 36). Both DoD and you may NASA received study in the four satellites launched out of 1964-1968, however the DoD and gotten it away from calculating products into the its own satellites like CORONA and you will SECOR. Typically, new DoD refused to tell NASA the newest intense analysis regarding its very own satellites and canned studies much more right than was derived solely from the NGSP. Brand new resulting argument between DoD and you will NASA of these techniques try taken to the eye from President Johnson into the 1968, but there's no sign it absolutely was fixed (File 37).
NASA arranged on the starting the fresh new Geodynamics Fresh Ocean Satellite-step three (GEOS-3) that have good radar altimeter whose study manage make more right the law of gravity activities than nearly any computing devices previously flown. The info could well be used to meet civil requirements and by the fresh new You.S. Navy to evolve the accuracy of the submarine-released ballistic missiles (SLBMs).
