Survey responses can be provided until 31 December 2018. The survey can be completed online or may be posted.


The General Lighthouse Authorities of the UK and Ireland are conducting a survey to gauge current and future user requirements for their Differential GPS service.

The General Lighthouse Authorities of the UK and Ireland—Trinity House, the Northern Lighthouse Board and the Commissioners of Irish Lights—operate 14 Differential Global Positioning System (GPS) reference stations which provide corrections to GPS, thereby enabling greater positional accuracy and integrity in the user’s position.

The authorities are now surveying users across a wide variety of sectors to better understand how the Differential GPS service is being used. The Differential GPS service currently provides corrections for GPS (single frequency) only, but the technology is being developed to enable corrections to be provided for all Global Navigation Satellite Systems (GNSS), should there be a requirement. The survey results will be used to establish current and future user needs.

In order to ensure that we are well-informed and therefore able to make the best provision for future requirements, we are looking to gather as much user feedback as possible and encourage all users, from all sectors, to complete the survey.

It is important to understand that this is a survey about the Differential GPS service and not GPS / GNSS.

More information on the Differential GPS system and related technologies is provided in the annex of the document linked below.

The survey will take about five minutes to complete. All responses will be kept confidential and any identifiable information will be managed in accordance with General Data Protection Regulation (GDPR) and Data Protection laws.
