ANTENNA DEVICE FOR POSITION DETECTION, POSITION DETECTION DEVICE EQUIPPED WITH THIS ANTENNA DEVICE, AND POSITION DETECTION METHOD
First Claim
1. A position detection device that determines a current position using a GPS that receives a signal from a satellite orbiting around the earth to determine the current position,wherein the position detection device is capable of data communication with an antenna main body that comprises:
- an antenna member provided, at an end thereof, with a receiving section for receiving the signal from the orbiting satellite; and
a rotation mechanism for rotating the antenna member circularly in a horizontal direction at a substantially uniform speed, andthe position detection device receives the signal from the orbiting satellite received by the receiving section.

Abstract
Provided is an antenna device for position detection that can determine the current position, using a GPS receiver with a simple structure, with high accuracy comparable to that of an expensive positioning device, and also provided are a position detection device provided with the antenna device and a position detection method. The current position is determined using a GPS that receives signals from satellites orbiting around the earth and determines the current position. Data communication is performed with an antenna main body including: an antenna member provided, at an end thereof, with a receiving section for receiving signals from the orbiting satellites; and a rotation mechanism for rotating the antenna member circularly in the horizontal direction at a substantially uniform speed. The current position is determined based on the signals from the orbiting satellites that have been received by the receiving section.
