A Raytheon executive said that the company expects to deliver the Block O Launch and Checkout System to the U.S. Air Force this fall as part of the GPS Next Generation Operational Control System (OCX).  

In addition, the company completed a baseline procedure to recertify the troubled OCX program, which was approved by the U.S. Air Force, at the end of March, said Bill Sullivan, Raytheon vice president and program manager for GPS OCX, at the recent 33rd annual Space Symposium meeting in Colorado Springs, Colorado.

The International Hydrographic Organization (IHO) is the inter-governmental consultative and technical organization whose principal aim is to ensure that all the world’s seas, oceans and navigable waters are adequately surveyed and charted.

The Organization, based in the Principality of Monaco since 1921, provides the international standards for hydrography and nautical charting as well as ensures co-operation between countries in support of navigation safety at sea and the sustainable development of their maritime environment.

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.
