Wrist watch type GPS receiver
First Claim
1. A wrist watch type GPS receiver comprising:
- a GPS receiving antenna configured to be mounted to a user'"'"'s wrist;
antenna posture detecting means for detecting a signal receiving position of the GPS receiving antenna;
signal receiving operation controlling means for controlling a signal receiving operation on the basis of an output of the of the antenna posture detection means;
GPS receiving means for receiving a GPS signal by performing a signal receiving operation which is controlled on the basis of an output of the signal receiving operation controlling means;
received GPS wave processing means controlled on the basis of the output of the signal receiving operation controlling means for processing the output signal of the GPS receiving means; and
GPS data display means for displaying GPS data output by the received GPS wave processing means;
wherein the signal receiving operation controlling means includes means for controlling the GPS receiving means not to receive a GPS signal when the output of the antenna posture detecting means indicates that the GPS receiving antenna is not capable of receiving the GPS signal.

Abstract
The system includes an antenna posture detecting device for detecting an antenna posture condition where it is apparently impossible to receive the wave, and a received signal operation controlling device for temporarily interrupting the wave receiving operation, in the case where it is impossible for the antenna to receive the wave, until the wave receiving operation is again possible. The system may include a body movement detecting device for detecting an action of the user; an action judgement device for judging the action of the user on the basis of an output signal of the body movement detecting device; a signal receiving operation controlling device for controlling a signal receiving operation of the GPS receiving device from the judgement result of the action judgement device; a moving distance calculating device for calculating a moving distance of the user on the basis of an output signal of the body movement detecting device during a period of time when the GPS signal receiving operation is interrupted; and an alarm device for receiving a wave of a GPS receiving antenna on the basis of an output signal of the moving distance calculating device and for giving an alarm to the user for a position where it is easy for the GPS receiving antenna to receive the wave.
