Beidou navigation system

A recent New York Times article described a Russian request to the State Department to approve U.S. locations for one or more terrestrial signal monitors for Russia’s Glonass satellite navigation system, similar to America’s GPS, suggesting the request could have worrisome consequences.

According to the article, “The CIA and other American spy agencies, as well as the Pentagon, suspect that the monitor stations would give the Russians a foothold on American territory that would sharpen the accuracy of Moscow’s satellite-steered weapons.”

It had always been ICAO’s intent that civil user services provided by the global navigation satellite system (GNSS) should be free of charges or user mandates, except for certain optional applications such as fee-bearing accuracy enhancements with performance guarantees. Europe’s Galileo is expected to offer such optional enhancements. But Russia has announced that it will mandate the carriage of receivers for its Glonass constellation in all aircraft on its civil aircraft register. GPS may also be used, but only when integrated with a Glonass receiver and its adjuncts.

In a statement that surprised Western observers, China announced late last year that it will launch its own 35-satellite, GPS-like global navigation system over the next several years. Thirty of these satellites will fly in medium-earth orbits at around 12,000 miles altitude, similar to that of GPS, while the remaining five will be equally spaced around the equator in WAAS-like geostationary orbits and perform a similar service.
