Pre-workshop questionnaire

This is the pre-workshop questionnaire for the Alternative Timing and Synchronisation Technologies for Aviation Workshop. It will only take a few minutes and will really help to influence the day, in the most beneficial way for all, including also those who cannot attend the workshop personally.

Here, we seek to gain more understanding of what’s important to you, in your industry and we want to determine what needs there are, for new concepts in timing and synchronisation technologies. We aim to consider where the requirements are the most stringent.

We hope you can spend a few minutes to answer these questions - in particular the last one - where we would appreciate your own questions ahead of the workshop, so we can incorporate the important issues for your application domain in this valuable forum.

Question Title

* 1. In your view, is the risk of GNSS outages much higher for on-board systems than for the ground systems?

Question Title

* 2. Do you think the alternative timing and synchronisation solutions will help?

Question Title

* 3. In your view, what are the most demanding airborne systems and applications using GNSS timing?

Question Title

* 4. In your view, what are the most demanding airborne systems and applications using APNT timing? What is the most strict requirement regarding the time reference source for airborne systems (w.r.t UTC)?

Question Title

* 5. In your view, what are the most demanding on ground systems and applications using GNSS timing?

Question Title

* 6. In your view, what are the most demanding on ground systems and applications using APNT timing? What is the most strict requirement regarding the time reference source for on ground systems (w.r.t UTC)?

Question Title

* 7. There are several proven techniques complementary to GNSS to keep the time in ground aviation stations update with UTC time, such as radio clocks, Iridium time transfer and eLoran time transfer. Which one is the most preferable for you in case of GNSS time outage?

Question Title

* 8. In your view, which phase of the flight is the most critical in regards to APNT timing solution (ground/airborne)?

Question Title

* 9. In case of in-flight situations, which technologies are for you the most promising ones for the future?

Question Title

* 10. Would you be willing to pay more for better services?
