1. Introduction
The GPS (Global Positioning System) receiver unit is a device that receives the information from
satellites and outputs time signals synchronous to UTC (Universal Coordinated Time) to external
devices. The GPS receiver unit provides multiple outputs with optical signals for noise
immunity.
2. Characteristics
■ Highly accurate time signal output
Realizes a precision with respect to ±2µs for UTC (UTC: Universal Coordinated Time)
(excluding the propagation delay time on the cable).
■ Reduced cabling work
Adopting the signal superimposition method, the unit can be connected to an external device
with a single optical fibre only.
■ Application to a large system
Equipped with eight ports for output, the time distribution can be made to multiple devices
separated from each other by a maximum of 1 km.
■ High reliability
Aimed at reducing the number of parts through high-integration circuits and high-density
mounting technology, thus securing high reliability.
