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.

Features:

Provide drivers;

Provide  secondary development function library;

Provide computer timing software;

Integrate GPS receive decoding/B code timing decoding;

Switch directly when the error is below 1s between two time sources;

Application:

Data synchronous collection;

Timing area;

Computer time synchronized;

Astronomy measurement and geodesic survey;
