The Precise Time and Time Interval Systems and Applications (PTTI) meeting is an annual conference sponsored by ION with a technical program designed to disseminate and coordinate PTTI information at the user level, review present and future PTTI requirements, inform government and industry engineers, technicians, and managers of precise time and frequency technology and its problems, and provide an opportunity for an active exchange of new technology associated with PTTI.

ION’s winter meeting, the International Technical Meeting (ITM), is a more intimate conference with a technical program related to positioning, navigation and timing and includes the ION Fellows and Annual Awards presentations.

In 2020, PTTI will be co-located with the ION International Technical Meeting, in San Diego, California.
