Companies and organizations like Spirent Federal Systems share their products and insights in the exhibit hall. (Photo: ION) The ION GNSS+ 2017 conference and industry exhibition covers all aspects of satellite navigation technology. It takes place Sept. 25–29 at the Oregon Convention Center in Portland. The theme this year is “GNSS + Other Sensors in Today’s Marketplace.” The conference will feature two tracks: “Applications and Advances” focuses on safety of life, commercial and mass-market applications, and GNSS plans and policies. The second track, “Research and Innovations,” will concentrate on autonomous systems, multi-sensor applications and advanced GNSS algorithms. Short Courses taught by Internationally Recognized Leaders This year, ION is introducing complimentary Short Courses to be taught by internationally recognized GNSS experts and educators throughout the day on Monday, Sept. 25. Short Courses are designed to enhance the ION GNSS+ attendee experience while giving everyone an opportunity to learn from the rock stars in the field, according to ION’s Executive Director, Lisa Beaty. Presented in a lecture-style learning environment, the Short Courses are designed for professionals at any level of their career, for engineers and academics as well as the non-engineer wanting to boost their knowledge base in a particular area (such as members of the sales team). The Short Courses will taught by internationally recognized GNSS experts and educators. These instructors are masters in their field, the people who developed the technology and “wrote the textbooks.” The Short Courses are complimentary to all registered ION GNSS+ 17 attendees.
