So, first, who needs three more worldwide satnav systems, when we already have GPS? Why do these others want to spend billions just to keep up with the U.S.? There are two reasons: one political and the other practical. Politically, GPS has become a (not the) dominant technology in almost every part of human life around the world, in government, national security, industry and private life, with more than a billion receivers being used daily for thousands of applications, from simple to critical.

In its latest surprise move, would-be broadband provider LightSquared has morphed from a Chapter 11 bankruptcy case, with just a few months to find some closure with its creditors, to having an arrangement with them to allow it to continue in business and spend up to $190 million to fund its operations until September next year.

But this doesn’t mean the company will close down, fire all its employees and have a big, yard-sale type auction of all its possessions. Far from it. Chapter 11 is a useful process for companies in financial difficulties, in that it gives them protection from creditors while they seek ways to get things back to a reasonably normal state. And that recovery process can take several months, during which time the company’s management remains in exclusive control to take whatever actions it wishes before requesting its emergence from Chapter 11.

Jamming of GPS signals by North Korea may have contributed to the fatal crash of a Schiebel S-100 Camcopter UAV near Incheon, South Korea, on May 10. The small helicopter crashed into its ground control van, killing a Schiebel engineer and injuring the two remote pilots, both Koreans. The jamming started on April 28 and disrupted passenger flights into Seoul’s two airports, Kimpo and Incheon. South Korean government officials told local media that the jamming originated from the border town of Kaesong.

The basic precept of international GNSS is that public services will be available to all users without user charges or other fees. Separately, each system can transmit unique highly classified frequencies–such as the military codes used by the U.S.’s GPS, Russia’s Glonass, China’s Compass and the fee-paying civil applications for enhanced accuracy and integrity signals from Europe’s Galileo–but none affects public services.

Thales will provide its high-performance inertial reference system (HPIRS) and GPS to support all-weather operations by the new Embraer KC-390 military transport. The French avionics manufacturer described the new-generation HPIRS as a “technological breakthrough” in inertial and GPS navigation, combining advantages of a civil-certified product with the performance required for a military aircraft. It is the company’s first HPIRS contract for a military transport aircraft.
