An assisted GPS direct positioning estimation (DPE) technique for urban environment copes with a full spectrum of direct-line-of-sight and non-line-of-sight or multipath conditions. A new approach using signal visibility and specular reflection predictions within the DPE shows the potential to reduce positioning error from approximately 30 to 10 meters.
Three different low-cost sensor integrations, covering vehicle navigation in a range of environments, were explored and explained in the February webinar, “Automotive-Grade GNSS + Inertial for Robust Navigation.” The full webinar, slides and audio, is available for download now.
At the 12th EU Space Conference in Brussels, Thierry Breton made his first appearance as the new European Commissioner for Internal Market, and a remarkable appearance it was. In his position, Breton is charged with overseeing two of the European Commission’s Directorates General, that of Communications Networks, Content and Technology, also known as DG CONNECT, and Defense Industry and Space, also known, cleverly, as DG DEFIS. In French, defis means “challenges.”

The 2020 Space Symposium has been rescheduled for October 31—November 2 this year, to be held as usual at The Broadmoor in Colorado Springs. GPS in particular and GNSS in general always form an important part of the program. The annual assembly gathers leaders, innovators, and entrepreneurs from the civil, commercial, military, research, and international sectors of the world’s space community.

A new series of disciplined oven controlled crystal oscillators (OCXOs) incorporates an internal GNSS receiver with a 1PPS output, compatible with an external GPS, GLONASS, BeiDou or Galileo source. The IQCM-112 series from IQD is housed in a 14-pin 60mm square package.

Inspired by hard-working parents and an innate sense of compassion, GSA Head of Market Development Fiammetta Diani has traced a remarkable path to prominence in the world of satellite-based navigation.
EMCORE Corporation, a provider of advanced mixed-signal products serving the aerospace, defense and broadband communications markets, received the 2019 Raytheon Integrated Defense Systems (IDS) 5-Star Supplier Excellence Award for performance and partnership.

The European GNSS Agency (GSA) has posted a list of location-GNSS-Galileo based applications that may be useful tools against diffusion of COVID-19.
The applications cover a range of uses from supporting public authorities to assisting citizens in their everyday life under social distancing, closures and quarantines.

“Galileo is a true European success story,
and I am proud if in a small way I have contributed to building Europe with it.”
European Union space mainstay Carlo des Dorides, Executive Director of the European GNSS Agency (GSA) since 2011, retired from this post at the end of January. He was scheduled to speak at the 12th EU Space Conference in Brussels that month, but had to skip out when he was called to a special budget session of the European Parliament. It would have been his last appearance in a public forum as GSA chief. Inside GNSS met with him in Brussels to talk and to say farewell.

The Second Space Operations Squadron (2SOPS) at Schriever Air Force Base, Colorado officially took control of the second GPS III satellite in orbit on March 23. GPS III SV02 was designed and built by Lockheed Martin, with a payload provided by L3Harris.
A video rendering of a GPS III satellite gives a slightly vertigo-inducing experience of a ballet through space and above the Earth.
