Problems solved by technology
[0003] However, for the above several tracking methods, in actual operation, many unfavorable factors such as flight conditions and environmental obstacles will be encountered, and certain errors will appear in the target tracking at this time
Most of the current mainstream automatic tracking adopts the radio frequency signal strength method, which is to use the signal strength area received by the antenna feed itself to capture the signal. When this method encounters the signal being blocked or the signal is interfered, the telemetry data will appear. The real-time target position is lost due to loss, causing the computer to display error information and misleading monitoring personnel

Embodiment Construction
[0015] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These and other modifications and variations of the present invention can be implemented by those skilled in the art without departing from the spirit and scope of the invention.
[0016] figure 1 A system block diagram of an antenna control method for high-precision digital guidance according to an embodiment of the present invention is shown. The working principle of the method is briefly described below in conjunction with the system block diagram as follows:
[0017] The GPS data information on the aircraft is telemetrically transmitted in the form of electromagnetic waves through the airborne telemetry transmitting system; the ground receiving system receives and demodulates the radio frequency signal through the telemetry receiver 10, and sends the demodulated information to the telemetry front-end server. 20 performs bit frame synchroniz...

The invention provides a method for controlling antennas by high-precision data leading, which comprises the following steps: a, processing local GPS (global position system) positioning so as to acquire the first GPS data information; b, receiving the second GPS data information from an airborne GPS of an airplane; c, processing difference comparison to the first GPS data information and the second GPS data information so as to acquire GPS difference value information; and d, regulating direction and pitching of the antennas according to the GPS difference value information. Because the method disclosed by the invention processes the data leading to antenna direction pitching, high-precision automatic tracking is ensured.
Description
technical field [0001] The invention relates to wireless signal tracking, in particular to a high-precision digital guided antenna control method. Background technique [0002] At present, the tracking methods using the antenna are as follows: (1) Automatic tracking method: The method is to place the beacon transmitter within 150Km away from 100m and within a line of sight without obstructions. The antenna is required to be stable and not lost. The beacon is automatically tracked; the beacon transmitter is fixed on the test vehicle within 150Km away from 100m and within the line of sight of no obstructions. Stable and lossless automatic tracking beacon; (2) Single-pole manual tracking: the antenna can track according to the position of the crank handle; (3) Program tracking: Program tracking is started by the take-off signal, and sent by the monitoring computer when the sky control receives it. After the take-off signal is received, start the program tracking and run the an...
