About the survey

The General Lighthouse Authorities of the United Kingdom and Ireland (GLA), are conducting a short survey to gauge the current and future use of their Differential Global Positioning System (DIFFERENTIAL GPS) service.

The GLA operate 14 DIFFERENTIAL GPS reference stations which provide corrections to GPS (single frequency) enabling greater positional accuracy and integrity in the user’s position.  The survey results will be used by the GLA to assess this service in relation to the current and future user needs.  

Data Protection

The survey is being conducted by the tri-GLA Research and Radionavigation Directorate (R&RNAV). R&RNAV is not a legal entity in itself. It works on behalf of, and reports to, all three of the General Lighthouse Authorities that cover the British Isles and some associated territories: that is Trinity House, the Northern Lighthouse Board and the Commissioners of Irish Lights. Trinity House provides the legal framework within which R&RNAV works: as such the legal notices provided by Trinity House also cover R&RNAV. These notices can be found on the Trinity House website[1].

The General Data Protection Regulation (GDPR) and UK Data Protection laws set out how data which could identify a person must be handled.   This survey invites respondents to provide their name, email and phone number in Question 1.  This question is optional and any data provided will be used by the tri-GLA Research and Radionavigation Directorate (operating within Trinity House) to contact the respondent in the unlikely event that further information is required.   Respondents are free to leave this question blank if they wish.

The survey is being conducted to engage with end users to ascertain the requirements for future marine aids-to-navigation and therefore falls within the scope of a public task.   All data received will be uploaded to the SurveyMonkey online survey website and will be retained in full until the end of April 2019.  Before or on that date, all data will be deleted from the website and only the anonymised results will be retained within the Trinity House document management system.   Information on how SurveyMonkey securely holds data and how it complies with GDPR can be found on its website (https://www.surveymonkey.com/mp/gdpr/). 

Anonymised results from the survey will be consolidated into a report for consideration by the three GLAs, extracts of which may be presented to other interested parties, both nationally and internationally.  No personal data will be shared and no automated decisions will be taken.

Respondents have the right to request the deletion or amendment of their survey once submitted.  Any amendment or deletion requests will be actioned as soon as possible and should be sent to the survey coordinator – Dr Alan Grant (alan.grant@gla-rrnav.org). Should anyone wish to complain about any aspect of this survey they may contact the Trinity House Data Protection officer (data.protection@trinityhouse.co.uk) who will then investigate any complaint.

Finally, should any personal data be sent to us by a third party we will aim to provide you with the shared information, where relevant, within one month. We will also aim to inform you of the source that the personal data originated from and how we would like to use your personal data.
