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.

In 2021, PTTI will be co-located with the ION International Technical Meeting, in San Diego, California.

A commercial exhibit and pre-conference tutorials are held in conjunction with the conference.

Tutorials will be offered on January 25; technical sessions will take place January 26-28.
