#$%^&*AU2012207032A120120816.pdf#####ABSTRACT A system and method for assisting an integrated GPS/ wireless terminal unit in acquiring one or more GPS satellite signals from the GPS satellite constellation. 5 The invention includes a method for narrowing the PN-code phase search. That is, by accounting for the variables in geographic location and time delay relative to GPS time, the systems and methods of the present invention generate a narrow code-phase search range that enables the terminal unit to more quickly acquire and track the necessary GPS satellites, and thereby more quickly provide accurate 10 position information to a requesting entity.3/8 c'N 001 00 00 0 0 0 N lJ~) 00 LI-i 0 0 ~ ~ 0 LI-i 00 H 00 z 0 0 H 0 C) tI~)
