CTEK GPS PPS Signal Box

The CTEK PPS Box is a specialized signal conditioning device designed to bridge the gap between high-precision GPS equipment and standard computing interfaces. Its primary function is pulse stretching, which modifies short GPS PPS (Pulse Per Second) signals to make them readable by a computer’s serial interface. This ensures accurate time synchronization across multiple devices, making it an essential tool for hydrographic and navigation setups. Compact and energy-efficient, it serves as a reliable equivalent to market standards like the QPS PPS and Fix Adapter.
