Analysis, Modelling and Mitigation of Cross-Rate Interference in eLoran

Popis výsledku v původním jazyce

The General Lighthouse Authorities of the UK and Ireland (GLA) have selected eLoran as the most cost-effective way of complementing GNSS to provide resilient Positioning, Navigation and Timing (PNT) within their waters. The GLA has established eLoran Initial Operational Capability (IOC) in the seven busiest UK ports and port approaches along the east coast. It is anticipated that the GLA eLoran service will expand to cover all of the waters around the United Kingdom and Ireland, including the English Channel as part of the system's Final Operational Capability (FOC). This will require a number of new transmitting stations to be installed, which must work with those already in situ. Recent developments in new technology transmitters have created the potential for cost-effective eLoran signal provision. However, due to the nature of eLoran transmissions new stations can contribute as sources of interference which is often referred to as Cross-Rate Interference (CRI), and, if left uncompensated, is one of the major sources of measurement error. This paper reports on some of the findings of a PhD study which investigated the impact of CRI on the positioning accuracy of eLoran and explored ways of mitigating this impact through modern receiver signal processing and the judicious choice of the signal Group Repetition Intervals (GRI).
