Embodiment Construction
[0074] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0075] The invention belongs to the field of satellite navigation, in particular to a modulation method and generation method of a Security Positioning and Timing (SPT) signal based on a low-orbit mobile communication satellite.
[0076] The low-orbit mobile communication satellite signal based on the invention adopts a time-division / frequency-division / space-division hybrid system, that is, the downlink service signal adopts the TDMA+FDMA+multi-beam system, and the uplink and downlink are also frequency-divided.
[0077] In order to achieve the above object, the present invention discloses a communication method based on low-orbit mobile communication satellite signals with anti-interference safety positioning and timing performance, such as figure 1 shown.
[0078] Generate a low-orbit mobile communication satellite signal for safe position...
