Rueil-Malmaison, France-based SBG Systems will unveil Qinertia, its in-house post-processing software, at the Ocean Business show, April 4-6 at Southampton, U.K.
After the survey, this full-feature software is designed to give access to offline real-time kinematic (RTK) corrections, and process inertial and GNSS raw data to further enhance accuracy and secure the survey.

The first generation of the Galileo Program, at satellite and ground segment level, has been “an enormous success,” according to Miguel Manteiga Bautista, who recently spoke with Inside GNSS at his office at the European Space Agency’s European Space Research and Technology Centre (ESTEC) in Noordwijk, Netherlands.

Q: Would you prefer to have more signals or more satellites?
A: This is somewhat of a classic GNSS question, but before getting to the answer, let’s seek some clarity about what is being asked. First, by definition, “more” signals or “more” systems must be referenced against some baseline configuration. This is commonly assumed to be a GPS L1 C/A solution, and this assumption is also used herein.

Speakers at the 9th Annual Conference on European Space Policy wasted no time in addressing the somewhat worrying failure of several Galileo onboard clocks, as revealed by European Space Agency Director General Johan-Dietrich Woerner at a press briefing earlier in January in Paris. He made clear at the time that the clock failures, while indeed troubling, had had no effect on the operational integrity of the Galileo system.

The GPS community and Virginia-based Ligado are weighing new and upcoming test results as the standoff over interference with satellite navigation services enters its seventh year.
The dispute centers on the company’s now modified proposal to build a terrestrial wireless network supported by frequencies originally allocated for satellites. Though there had been a move some years earlier to augment the satellite services with ground stations the company’s first plan envisioned some 30,000 high-powered ground terminals.

A partnership between Swift Navigation and Carnegie Robotics announced this week is expected to yield a line of navigation products for autonomous vehicles, outdoor robotics and machine control.
San Francisco-based Swift Navigation is a startup building centimeter-accurate GPS technology designed to power a world of autonomous vehicles, while Carnegie Robotics, located in Pittsburgh, Pennsylvania, provides advanced robotics sensors and platforms for defense, agriculture, mining, infrastructure and energy applications.

With two federal budgets in play simultaneously, defense spending increases being proposed from multiple directions and a looming government shutdown it’s easy to lose track of where things stand with GPS funding.

Ligado, which has been in a standoff with the GPS community over interference issues for more than six years, is developing a new high-precision location (HPL) augmentation system for GPS.
The new HPL service will use real-time kinematic- (RTK-) based solutions for augmentation of high-precision receivers, said Tamara Casey, Ligado’s chief technology officer, during Satellite 2017.
