From page 8...
... Military receivers should be developed that compensate for ionospheric errors when [~ is jammed, by improved software modeling and use of local-area ionosphenc corrections. In the interim time before such enhancements can be fielded by the military, various operating disciplines, which are discussed in Chapter 3, can be used to minimize the impact of C/A-code jamming on the ability to acquire the Y-code directly.

From page 9...
... The operational control segment Kalman Fiber should be improved to solve for ad GPS satellites' clock and ephemeris errors simultaneously through the elimination of partitioning, and the inclusion of more accurate dynamic models. These changes should be implemented in the 1995 OCS upgrade request for proposal.
