Abstract

The invention discloses a satellite-borne dual-mode transmitter which comprises a power supply controller, a constant temperature crystal oscillator, a temperature compensation crystal oscillator, a frequency multiplier, an amplifier, a telemetry modulator and a data transmission modulator. The satellite-borne transmitter can work in a telemetry transmitter mode and a data transmission transmittermode, the power supply controller controls power supply of all circuits in the transmitter according to a control instruction, and when the satellite-borne transmitter needs to work in the telemetrytransmitter mode, the power supply controller supplies power to the temperature compensated crystal oscillator, the frequency multiplier, the telemetry modulator and the amplifier; when the system needs to work in a data transmission transmitter mode, power is supplied to the constant temperature crystal oscillator, the frequency multiplier, the data transmission modulator and the amplifier; and when the transmitter does not work, all circuits are not powered. The invention has the technical characteristics of simple design, low cost, easy integration, low power consumption, light weight and strong universality.

Description

technical field [0001] The invention belongs to the field of space-borne measurement and control digital transmission transmitters, in particular to a space-borne dual-mode transmitter. Background technique [0002] At present, in my country's satellite measurement and control digital transmission subsystem, the transmitter is generally required to output telemetry and digital transmission signals to the ground station. It's not any different than the original way of working. [0003] The existing technology has the following defects: the separate design of the telemetry transmitter and the digital transmission transmitter has high cost, high power consumption, and heavy weight, which reduces the carrying capacity and operating capacity of the satellite in disguise, increases the cost of the satellite, and limits the overall capacity of the satellite. design. Contents of the invention [0004] The technical purpose of the present invention is to provide a spaceborne dual-...
