GoLINC Precision Reference (pREF) is an all-in-one precision navigation system designed for onboard and wayside precision navigation. Precision Reference designates a system where centimeters of accuracy are important. This solution contains both an onboard-roving component, the Precision Navigation Module (PNM), as well as a base-station component, the Precision Reference Module (PRM). The primary component in the PNM and PRM is a high-precision Global Navigation Satellite System (GNSS) receiver for determining position.
The PNM primarily functions as a roving high-precision GNSS module that can determine position. The PRM has a GNSS receiver for generating RTCM Differential or Real Time Kinetic (RTK) corrections. A customer communication path is required between the PNM and PRM.
GoLINC is integrated with Wabtec’s PTC solution, which functions as a safety overlay and is designed to enforce existing railroad signal indications and other operating rules. Moreover, PTC provides critical information about proximity of work zones, movement authorization, switch positions and other operational data. Beyond PTC, the high-precision GNSS infrastructure along the track enables other applications such as drone flights for rail inspection.
