By Inside GNSSWell, I could have taken up the subject of the deteriorating condition of U.S./Soviet, excuse me, U.S./Russian relations. But there are only so many windmills that I have time to tilt at.
So, rather than tracing the dissolution of bilateral GNSS cooperation in the wake of Russia’s reclaiming the Crimea and, who knows, perhaps eventually a large swath of eastern Ukraine, I thought I’d turn to an only slightly more remediable issue — GNSS carriage requirements.
By Inside GNSSIn the “gee-whiz” awesomeness of proliferating GNSS apps, it’s sometimes hard to remember that Global Positioning System originated as a military system designed to meet strategic and tactical needs on the battlefield.
And, with the U.S. Air Force continuing its 40-year mission as the executive agent for sustaining GPS, that undiminished military role plays no small part in ensuring the availability and reliability of the U.S. contribution to the GNSS system of systems.
By Inside GNSSThe Russian GLONASS system, which had appeared to be recovering from a series of organizational and technical problems in recent years, suffered two major disruptions during April.
By Inside GNSSWorking Papers explore the technical and scientific themes that underpin GNSS programs and applications. This regular column is coordinated by Prof. Dr.-Ing. Günter Hein, head of Europe’s Galileo Operations and Evolution.
