Galileo Success, Flexibility, and a Look Ahead

Miguel Manteiga Bautista

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.

Would you prefer to have more signals or more satellites?

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.

Bad clocks, Brexit and what’s happening at the European Space Policy Conference

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.

Ligado Test Results Roll In

Figures and Charts

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.

Location Privacy Poised to Take a Hit

The U.S. Congress is prepared to deliver the coup de grace to a new rule aimed at protecting the personal information — including the geolocation — of broadband internet users. The move, one of a number aimed at eliminating Obama-era regulations, would slice through months of debate, and federal regulators’ own backpedaling, to kill the pro-privacy rule in a way that makes resurrecting it extremely difficult.

Study Proposes Satellite Navigation System for Mars

Universal and precise positioning services on Mars may not be just science fiction in our future. A proposed theoretical concept of a satellite navigation system for Mars promises a solution for future manned missions and future planetary exploration robotic missions to the red planet, according to new research released this week.
