Patent attributes
Provided is a navigator, which reduces current consumption in a gap of an orbiting GPS satellite signal. A method for reducing the current consumption of the navigator is disclosed. The method includes measuring the strength of a geostationary GPS satellite signal; stopping the tracking of an orbiting GPS satellite signal when the measured geostationary GPS satellite signal strength is less than a critical value and such a state passes a preset time; performing a navigation mode where an orbiting GPS satellite signal and a geostationary GPS satellite signal are tracked when the measured geostationary GPS satellite signal strength exceeds the critical value. The navigator reads a gap of an orbiting GPS satellite signal using a geostationary GPS satellite signal and stops tracking the orbiting GPS satellite signal in the gap, thereby reducing its current consumption.
