GLOBAL POSITIONING SYSTEM LOG WITH LOW POWER CONSUMPTION
First Claim
1. A global positioning system (GPS) log with low power consumption comprising:
- an antenna;
a GPS module connected to the antenna to receive signals from satellites, computing speed and positions of the GPS log and determining intensity of the signals;
a power control module connected between a power source and the GPS module to provide power to the GPS module;
a main control module connected to the GPS module and the power control module to retrieve the computing results of the GPS module, predetermining a variable power providing period and controlling the power control module to periodically provide power to the GPS module according to the present power providing period;
a power adjusting unit connected to the main control module, analyzing the computing results of the GPS module and assisting the main control module to adjust the power providing period; and
a memory connected to the main control module to store the computing results of the GPS module.

Abstract
A global positioning system (GPS) log with low power consumption has an antenna, a GPS module, a power control module, a main control module, a power adjusting unit and a memory. The main control module is connected to the GPS module and the power control module to retrieve the computing results of the GPS module and controls the power control module to periodically provide power to the GPS module according to a predetermined and variable power providing period. The power adjusting unit is connected to the main control module, analyzes the computing results of the GPS module and assists the main control module to adjust the power providing period. Since the main control module automatically adjusts the power providing period, the GPS log does not deplete unnecessary power on the GPS module. Therefore, the power consumption of the GPS log is reduced and the GPS operates longer.
