Method for operating an active gps receiver using a bts position remote input
First Claim
1. A method of operating a GPS receiver based on a remote input of a position of a base station in a mobile communication system, the method comprising the steps of:
- self-checking an internal operation when power is initially applied;
requesting positional information to a Base Station Management station (BSM) when the GPS receiver is in a normal state;
setting an operating position according to the positional information when the information is received within a set time after requesting the positional information; and
entering a normal operating state when at least one satellite signal is received.

Abstract
The present invention relates to a method of operating an active GPS receiver using a base station position remote input. So that the GPS receiver can operate normally and at a high speed even in a base station'"'"'s initial power authorization which may be under a poor receiving circumstances by inputting a base station'"'"'s position information to a GPS receiver form a distance. This invention comprises: checking an inside activation by itself after power is initiated and authorized; requesting position information to a BSM when within a normal state; setting the action information by the received position information when the position information is received after the above position information is requested; and entering a conventional operating state when at least more than one satellite signal is received. In addition, after requesting the position information, when position information is not received within a set time, outputting of the position information is automatically initiated. The position information is calculated when satellite signals of more than four of the above items are received by checking whether more than four satellite signals are received or not. The above position information calculation value is accumulated during a prescribed time. When the accumulated time exceeds the above prescribed time, an action position is set to a calculated position information.
