Title:
RADIO TRANSMISSION METHOD OF IMAGE FROM TRAVELLING OBJECT
Document Type and Number:
Japanese Patent JPH07312517
Kind Code:
A
Abstract:

PURPOSE: To provide the image radio transmission method from a travelling object by using an antenna mounted to the travelling object with sharp directivity.

CONSTITUTION: A position of a travelling object 1 is measured by a satellite navigation system and a transmission azimuth and an elevating angle of a directivity antenna 4a mounted to the travelling object 1 are obtained by the position of the travelling object 1 and a position of a directivity antenna 5a of a stationary station 2. The antenna 4a of the travelling object is directed to the transmission azimuth and elevating angle and an image signal from an image pickup device 3 and a position signal of the travelling object 1 are sent. Reception azimuth and elevating angle of the antenna 5a of the stationary station are obtained from the position signal of the travelling object 1 received by the antenna 5a of the stationary station and the position of the antenna 5a of the stationary station, the antenna 5a of the stationary station is directed to the reception azimuth and elevating angle to oppose the antenna 4a of the travelling object to the antenna 5a of stationary station. The measurement and processing cycle from the measurement of the position of the the travelling object 1 till the opposition of both the antennas 4a, 5a for each movement of the travelling object 1 and the image from the image pickup device from the position after the movement is sent to the stationary station 2 depending on the movement of the travelling object 1.
