Product Overview

The TSAT-PCI-U is a complete GPS synchronized timecode reader/generator system package that includes the GPS Receiver/Antenna (housed in a common enclosure) and a circuit card assembly for the PCI bus.

The board synchronizes its on-board clock to Coordinated Universal Time (UTC). Other features include a time-tag TTL input, a programmable “heartbeat” pulse or squarewave output (with interrupt capability), and a programmable “match” start/stop time output (with interrupt capability).

In the unlikely event that the reception of the satellite signals are lost, the board continues to increment time (“freewheel”). When the signals are re-established, the board resumes synchronization automatically.

The GPS satellites provide Coordinated Universal Time (UTC) accurate to within one microsecond. They also provide position with longitude, latitude, and elevation.

A programmable time offset allows for compensation for cable delays.
