No longer consigned to predicting what might one day happen, the folks at the Galileo program can now look at and talk about what is happening right now, starting with initial services. To help us understand what’s going on, we enlisted no less than Matthias Petschke, Galileo Program Director at the European Commission (EC).By Peter Gutierrez
Though the United States has been working on a backup for GPS for years, and was actually close to completing an equipment update to that end in 2009, Europe may be the first to put in place a fully independent alternative for positioning and timing data — an economic insurance policy against satellite navigation signals being jammed or disrupted.By Dee Ann Divis
Looking over the initial budget of the Trump administration, we can safely say that the president and his timorous collaborators on Capitol Hill have a maximalist concept of providing for “the common defense” and a minimalist one for promoting “the general welfare,” two of the six missions enshrined in the preamble of the U.S. Constitution.By Inside GNSS
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.By Inside GNSS
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.By Peter Gutierrez
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.By Dee Ann Divis
