EXTERNAL GYROSCOPE AND METHOD OF USING THE SAME TO ASSIST IN NAVIGATION AND POSITIONING
First Claim
1. A method of using external gyroscope to assist in navigation and positioning, the method being applicable to a navigator, which is able to determine a user'"'"'s position, moving direction, and moving speed based on a GPS signal, the method comprising the following steps:
- a. connecting an external gyroscope to the navigator, so that the navigator acquires angular displacement and acceleration data generated by the external gyroscope;
b. acquiring a GPS signal for calculating current moving direction and moving speed;
c. combining the angular displacement and acceleration data with the current moving direction and moving speed to calculate and generate a positioning signal for a next position; and
d. replacing the GPS signal with the positioning signal for the next position, and transmitting the positioning signal to the navigator.

Abstract
An external gyroscope is connectable to a navigator of any type to assist in navigation and positioning. The navigator has at least one first connector. The external gyroscope includes a mini-gyroscope adapted to generate angular displacement and acceleration data, a second connector for correspondingly connecting to the first connector, and a control unit. The control unit acquires the angular displacement and acceleration data and then directly transmits the same to the navigator. Alternatively, the control unit calculates the acquired angular displacement and acceleration data to generate a positioning signal for a next position, and then transmits the positioning signal to the navigator. A method of using the external gyroscope to assist a navigator in navigation and positioning is also provided.
