Embodiment 1

[0020] The timing reference sources of this system can include BDS / GPS, B code, PTP Ethernet, PTPE1 interface, internal frequency source, external frequency source, and the external timing methods of this system include 1PPS+TOD, B code, NTP, PTP, etc. The high-precision satellite navigation timing and direction-finding module receives GPS or Beidou signals, outputs positioning, direction-finding and timing information, and sends them to the embedded processor and FPGA of the front board through the backplane. The embedded processor will analyze the positioning and direction finding information and transmit it to other functional boards through the backplane. The FPGA obtains the time information through the navigation message analysis module, and sends 1PPS+TOD to the time source selection module; the B-code signal input by the rear board is transmitted to the B-code encoding and decoding module of the FPGA through the backplane, and the 1PPS+TOD information is analyzed and tr...
