Embodiment Construction

[0030] Such as figure 1 As shown, the present invention includes a pulsar simulation computer, a data receiving buffer board, and an analog output board, wherein the pulsar simulation computer simulates the pulsar data received by the satellite and sends it to the data receiving buffer board through a USB bus, but is not limited to USB bus, the data receiving buffer board puts the received data into the buffer, and sends it to the analog output board through the 8-bit data bus and 1-bit signal clock when needed, and the analog output board converts the received digital signal into an analog signal, thereby generating Pulsar signal.

[0031] Such as figure 2 As shown, the pulsar simulation computer is equipped with a man-machine interface, a pulsar signal simulation unit, a pulsar characteristic parameter library and a satellite ephemeris library. The human-computer interaction interface is used to allow the user to select the pulsar model and satellite orbit, and to allow t...

Abstract

The invention discloses a pulsar signal simulator mainly solving the problem that X-ray pulsar signals only can be obtained by a satellite carrying X-ray detector at present. The system mainly comprises a pulsar analog computer, a data receiving buffer board and an analog signal output board, wherein, the pulsar analog computer stimulates user input according to human-computer interaction interface, extracts information in a pulsar characteristic parameter library and a satellite ephemeris library, generates pulsar data received in the satellite operation process, and transmits the pulsar data to the data receiving buffer board via a data port; the data receiving buffer board puts received data into a cache and transmits the data to an analog output board if needed; the analog output board converts the received digital signal into an analog signal so as to stimulate and generate X-ray pulsar signals. The invention can stimulate the pulsar signal received in the satellite operation process, has flexible arrangement and wide application range, and can be used for proving the X-ray pulsar navigation theory method and researching engineering technology.

Description

technical field [0001] The invention belongs to the technical field of electronic circuits, and relates to a signal simulator, in particular to a pulsar signal simulator, which is suitable for the verification of the theoretical method of the pulsar navigation system and the research of engineering technology. technical background [0002] In 2004, Tony Tether, director of the US Defense Advanced Research Projects Agency, revealed at an academic conference held at Utah State University that the Tactical Technology Office of the US Defense Advanced Research Projects Agency is conducting research on the "Autonomous Navigation and Positioning of Basic X-ray Sources" program. As a new astronomical navigation method, X-ray pulsar autonomous navigation has strong anti-interference ability, high reliability, wide coverage, fixed position in the heliocentric inertial system, and no need to provide ephemeris, which has important strategic significance and huge potential. Development ...
