Method for directly acquiring code type encrypted military signal from satellite by precise positioning service receiver of global positioning system, involves acquiring encrypted signal implemented in case of failure of one attempt

摘要

The method involves directly acquiring an encrypted signal implemented on one integration time at one attempt (101), where the integration time corresponds to the hypothesis of the absence of scramblers in an environment of a receiver of a global positioning system. Another encrypted signal implemented in case of failure of the attempt on another integration time is directly acquired at another attempt (105), where the latter integration time corresponds to the hypothesis of the presence of the scramblers in the environment of the receiver, and is higher than the former integration time. An independent claim is also included for a receiver for a global positioning system, comprising a monitoring unit.
