  • ION Co-Locates ITM, PTTI Conferences for 2016

    Two of the Institute of Navigation’s (ION’s) conferences — the International Technical Meeting (ITM) and the Precise Time and Time Interval (PTTI) Meeting — will be co-located for 2016. One registration fee gives attendees access to both technical events and a commercial exhibit. The co-located conferences will take place Jan. 25-28, 2016, at the Hyatt Regency Monterey in Monterey, Calif.

    Abstracts are due Oct. 2, 2015. Submission requirements have changed, and depend on the session the abstract is submitted for. Review the call for abstracts for more information.

    This year’s joint ITM/PTTI Plenary Session is “Autonomous Vehicles – Beyond the Navigation Technology.” The session will address issues outside of navigation technology, including legal issues, regulatory challenges, transitional periods, markets enabled by autonomous operation and similar topics beyond the core navigation technology.

    ITM is ION’s winter meeting, which features peer-reviewed technical papers related to positioning, navigation and timing, and includes the ION Fellows and Annual Awards presentations.

    PTTI is the annual technical conference 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 regarding precise time and frequency technology and its problems, and provide an opportunity for an active exchange of new technology associated with PTTI.

    The co-located 2016 ITM and PTTI meetings will feature a technical exhibit and showcase of products and services related to positioning, navigation and timing. For more information on exhibiting, contact ION or go to www.ion.org.

  • Get a Galileo Position Fix? ESA Wants to Give You a Prize

    Get a Galileo Position Fix? ESA Wants to Give You a Prize

    Javier Benedicto, ESA’s Galileo Project Manager, looks on as Europe’s own satellite navigation system performs its historic first position fix of longitude, latitude and altitude. The position fix took place at the Navigation Laboratory at ESA’s technical heart ESTEC, in Noordwijk, the Netherlands on the morning of March 12, 2013, with an accuracy between 10 and 15 meters — expected taking into account the limited infrastructure deployed so far. Horizontal accuracy reached as high as 6 m. The left-side screen shows the position fix while the right side screen shows the position of the four Galileo satellites and their current signal coverage.

    Did you get a fix on four Galileo satellites? Then there could be a certificate in it for you! ESA will recognize Galileo pioneers with commemorative certificates to the first 50 entities who document their achievement of a past or present fix. Details of how to apply are provided here.

    To mark the first anniversary of Galileo’s historic first satnav positioning measurement, ESA plans to award certificates to groups who picked up signals from the four satellites in orbit to perform their own fixes.

    In 2011 and 2012 the first four satellites were launched — the minimum number needed for navigation fixes.

    On March 12, 2013, Galileo’s space and ground elements came together for the first time to perform the historic first determination of a ground location — the Navigation Laboratory of ESA’s Technical Centre in Noordwijk, the Netherlands.

    From this point, generation of navigation messages enabled full testing of the entire Galileo system — not just by ESA and its industry and institutional partners but also by any entity with a customized satnav receiver.

    ESA’s Galileo team has heard about position fixes carried out by organizations and companies all over Europe and beyond, including as far away as Vietnam.

    A year after the first fix, ESA is recognizing these Galileo pioneers with commemorative certificates to the first 50 entities who document their achievement of a past or present fix.

    Applicants should send in their name, address, details of the receiver they used, the start and end time of their fixes in Universal Time Coordinated (UTC) and a plot of their latitude/longitude position fixes overlaid on a map, such as Google Earth. Submissions should be sent to [email protected] within the next two months. Certificates will be sent out after May 12, along with an online results update. See details of how to apply here.

    The first Galileo services are scheduled to begin later this year, as more satellites are delivered into orbit. The next launches will occur in the second half of this year, each with two satellites aboard a Soyuz ST-B. They will take place in close succession to build up the constellation.

    Many satnav receiver chips are already technically Galileo ready, requiring only software upgrades from their manufacturer to begin working with Galileo signals along with GPS and other international satnav systems.
