After careful consideration, the ION is announcing that the IEEE/ION Position Location and Navigation Symposium (PLANS) scheduled to take place April 20-23, 2020, in Portland, Oregon has been cancelled. The decision to cancel this meeting was based on:

  • The World Health Organization has declared Coronavirus (COVID-19) a pandemic.

  • The U.S. government has restricted travel into the U.S. from Asia and Europe (United Kingdom excluded).

  • The Governor of Oregon has called for all gatherings of over 250 people to be cancelled for the next four weeks.

We urge those who were planning to attend the meeting to expedite flight and hotel cancellations and contact the hotel directly to cancel your room reservation. IEEE/ION PLANS 2020 registration and exhibit fees will be fully refunded by March 31. ION will communicate directly with scheduled program participants, registered attendees, and exhibitors.

Should PLANS 2020 be rescheduled, we will notify you once those arrangements have been finalized.

We ask for your patience as we work diligently to address questions and provide additional information.

Media/questions should be directed to the Institute of Navigation at or call +1-703-366-2723.
