GSA Issues Second GNSS Market Report: 1.1 Billion Units by 2020

[SIGNALS EXCLUSIVE] The European GNSS Agency (GSA) has published its second GNSS market report, including a special focus on maritime and surveying application markets and refining its projections of unit and sales revenue volumes through 2020. (more)

UK Patent Initiative Nears Approval in U.S., Raises Doubts about New GPS, Galileo Civil Signals

The U.S. Patent and Trademark Office (USPTO) is weeks away from approving a controversial British patent that could force American consumers to pay more for GPS navigation devices and even affect the operations of the American military. The patent is one of dozens filed around the world by the British defense establishment asserting ownership of technology developed jointly by the United States and the European Union (EU). The patents lay claim to a signal structure crafted by American and European experts to make Europe's still-emerging Galileo satellite navigation system interoperable with GPS and improve service for users of both systems.

Thinking Aloud: IP Rights & Wrongs

As Desi Arnaz often said to Lucille Ball during an "I Love Lucy" episode on TV, "You've got some 'splaining to do." I refer, of course, to the untoward and unexpected initiative by the British Ministry of Defense (MoD) to patent the technical innovations that underlie the planned next generation of civil GNSS signals.

Demystifying GLONASS Inter-Frequency Carrier Phase Biases

A team of Septentrio engineers has identified the origin of well-known decimeter-level linear biases affecting GLONASS carrier phase measurements as a function of how measurements are generated in the digital signal processing (DSP) section of a GNSS receiver. Contrary to the common assumption that analog-induced biases are dominant, these DSP-induced biases are, by far, the major cause of GLONASS inter-frequency biases and can be compensated for. (more)

Air Force Awards Service Support Contract for GPS III SVs

The U.S. Air Force has awarded Lockheed Martin a $68 million contract to provide mission readiness, launch, early orbit checkout, and on-orbit operations engineering support for the first two GPS III space vehicles. Under the contract, Lockheed Martin will provide technical support to the Air Force's 2nd Space Operations Squadron (2SOPS) and monitor the health and performance of the first two GPS III satellites from launch through their 15-year operational design lives.
