Beacon machine for telemetering flying ball training

Abstract

The invention discloses a beacon machine for telemetering flying ball training. The beacon machine comprises a power supply, wherein the power supply is communicated with a wide-voltage circuit voltage stabilizer; the wide-voltage circuit voltage stabilizer is communicated with a first low-dropout voltage stabilizer and a second low-dropout voltage stabilizer; the first low-dropout voltage stabilizer is communicated with a controller, the input end of the controller is communicated with a power frequency communication serial port, the output end of the controller is communicated with a variable-frequency phase lock, the variable-frequency phase lock is connected with an antenna for transmitting signals, the output end of the second low-dropout voltage stabilizer is respectively communicated with the variable-frequency phase lock and a crystal oscillator, and the crystal oscillator is communicated with the variable-frequency phase lock. The beacon machine for telemetring flying ball training is a beacon machine module which is small in size, adjustable in power frequency program control, high in performance, wide in bandwidth and stable in work. The phase noise and spurious suppression characteristics are relatively high, and the frequency spectrum purity of the transmitter is improved, so that the sensitivity test precision of the receiver is improved; meanwhile, the method hasthe characteristics of high frequency stability and accuracy and ultralow phase noise.

Description

technical field [0001] The invention relates to the technical field of spacecraft telemetry, in particular to a beacon machine for telemetry flying ball training. Background technique [0002] The measurement and control system is mainly responsible for orbit measurement, image and telemetry monitoring, remote control operation, data injection, flight control, etc. of spacecraft (rockets, satellites, etc.). Indispensable and important part of aerospace engineering. Telemetry equipment is an important part of aerospace measurement and control equipment, and is the core equipment for the measurement of the active section of the launch vehicle. [0003] Capturing and tracking the target is a prerequisite for telemetry equipment to demodulate the data of the target spacecraft (rocket, satellite, etc.), and it is also an important link that is crucial to the success of the mission. Therefore, training telemetry dynamic target tracking is indispensable in actual combat training....
