... Recommended Technical Improvements to Military User Equipment Rapid, Direct Y-Code Acquisition Current military receivers are designed to first acquire the more powerful C/A-code before handing over to the encrypted Y-code. Upon receiver restart, or following a loss of signal lock, a PPS receiver must go through acquisition in which a two-dimensional timefrequency search is carried out by trial correlations.

... A method for improving Lo ionospheric corrections in an L jamming env~ron~T~ent is addressed later in this chapter. In order to obtain direct Y-code access, the signal acquisition processing capability of current PPS receivers must be improved through the use of massively parallel correlators, built using application-specific integrated circuit (ASIC)
