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.


The Position Location and Navigation Symposium (PLANS) is a biennial technical conference that occurs in the spring of even numbered years. Our mission is to provide a forum to share the latest advances in navigation technology. Read about the history of PLANS here.

This conference is jointly sponsored by the Aerospace and Electronics Systems Society (AESS), and the Institute of Navigation (ION). The AESS is sponsored by the IEEE, which is the world's largest professional engineering organization. The ION is the world's premier professional organization for the advancement of positioning, navigation and timing.

The PLANS conference is a four day conference with 1 day dedicated to tutorials and three days to technical sessions.

The tutorials provide attendees with the opportunity to learn about navigation technology from well-known industry experts. A variety of tutorials are offered to serve the professional needs of both newcomers and those well versed in the field of navigation. This year's tutorials include a wide range of navigation subjects from core navigation fundamentals to in-depth classes about the latest technologies.

Twenty-four half-day technical sessions are offered over a three day period, with four sessions running simultaneously each morning and afternoon. At the technical sessions scientists, researchers and engineers from around the world present their latest work in the field of navigation. The presentations range from fundamental research, to applications, to field test results. The topics include sensors, systems, optimal integration of multiple sensors, and novel or emerging technologies used in the field of navigation.

In parallel with the sessions we host a technical exhibit at which navigation equipment component and system suppliers show their current products and most recent technical innovations. You can expect to see the latest, most innovative navigation products and services from top navigation companies, highlighted in the exhibit hall.

The mission of PLANS, to provide a forum for public and private enterprises or organizations from around the world to share the latest advances in navigation technology, is embodied in its logo of the stylized sextant and migratory bird.
