DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a GPS recording device for performing GPS positioning and recording measurement data.

PS (Global Positioning System)
em) is a system capable of detecting a received position and time based on a GPS signal transmitted from a satellite orbiting the earth, and can perform positioning over almost the entire area on the earth for 24 hours. Therefore, the GPS receiver is connected to the recording device, the current position and time are detected by the GPS receiver at predetermined time intervals, and the current position and time are recorded on the recording device. It can measure direction and speed, and measure the position of a balloon during climate observations.

[0003]

Here, the GPS receiver operates at predetermined time intervals to detect the current position and time. However, the interval of this predetermined time for operating the GPS receiver is limited. If the length is short, the amount of position and time data recorded on the recording device increases. Therefore, in this case, the recording capacity of the recording apparatus becomes insufficient, or a large-capacity recording apparatus needs to be used. Conversely, if the interval of the predetermined time for activating the GPS receiver is lengthened, the amount of position and time data recorded on the recording device decreases, but if the camera suddenly moves greatly, recording during that movement is not possible. There is a problem that it becomes impossible to analyze the route of the movement.

A broken circle indicates a range of a radius L centered on the GPS positioning position recorded in the recording device 2.

Therefore, even if the time interval for activating the GPS receiver 1 is shortened and the GPS positioning is performed at short intervals, the data of the position and time are recorded at a point in time when the distance from the position recorded in the recording device 2 is short. Is not recorded in the recording device 2, but is recorded in the recording device 2 only when the moving distance from the position recorded in the recording device 2 becomes longer to some extent, and the position and time data recorded in the recording device 2 Can be reduced. Therefore, the recording capacity of the recording device 2 does not become insufficient, and
This eliminates the need to use a large-capacity recording device 2.
