2025 IEEE/ION Position, Location and Navigation Symposium

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

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

The PLANS conference is a four-day conference with the first day hosting tutorials and three days dedicated 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 will 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 PNT. The presentations range from fundamental research, to applications, to field test results.

Topics being covered will include:

Inertial Sensing and Technology
Global Navigation Satellite Systems (GNSS)
Integrated, Collaborative, and Opportunistic Navigation
Applications to Automated, Semi-Autonomous, and Fully-Autonomous Systems
Technical papers from PLANS are peer-reviewed, and will be published in IEEE Xplore following the conference.

In parallel with the sessions, PLANS hosts a commercial exhibit during which suppliers and service providers showcase their products, innovations and services.
