SDI Timing PCI card is developed by our company independently.It is used in providing unified system time to military and high-accuracy civil for improving precision of the system time.The card can track GNSS signals at the same time or B code time source. IRIG-B gets Beijing Time as time sourcing,GPS gets UTC time as the time sourcing.The PCI cards has the function to judge whether the time source is valid.
