Objectives of the task

Describe solutions that can be applied by maritime service providers to reach a certain level of timing accuracy for their infrastructure and services.

Expected outcome

Guideline on timing and synchronisation

Strategic Alignment

Goal: G1

Strategy: S1

Scope (Describe key items that are in scope/out of scope)

Accurate timing is important for many services, used both as absolute time references and for synchronisation. For example, accurate station timing is a crucial point for radionavigation services, where the timing error of a station has direct impact on ranging error and position solution. Another example is that accurate clock synchronisation is needed for some types of encryption and message authentication services.

Therefore, the Guideline should analyse and present technologies that enable accurate station timing to help enable service providers to establish accurate station timing with respect to their needed accuracy level. Concepts for time synchronisation that are not dependent on GNSS should be included.

Brief and concise description of the work to be undertaken and programme milestones where appropriate.

Key milestones / Remaining key milestones for completing the task include:

• Review of existing IALA documents which deal with the issue of station timing and synchronisation
• Generate a list of available technologies and prove them for applicability
• Include aspect of cost benefit analysis of different concepts of time synchronisation and hold over technologies
• Detailed description of most promising approaches for, in particular, radionavigation station timing and synchronisation
