GNSS applications

July 10, 2014 - 3:34pm

Rockwell Collins’s flight management system (FMS) and global navigation satellite system (GNSS) receiver successfully enabled the first demonstrations of advanced arrival and departure flight operations for the European Union’s airspace-enhancing project called FilGapp (“filling the gap” in GNSS advanced procedures and operations), the company announced today. FilGapp is intended to create new, more efficient methods of navigating airspace using satellite-based navigation and advanced FMS functions.

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.

Russia plans to announce this month that its civil aviation fleet will be required to carry Glonass, that nation’s GNSS, or combined Glonass/GPS units, but not GPS on its own. The mandate will be unveiled at this month’s triennial ICAO Air Navigation Conference, and it has significant cost implications for western-built corporate aircraft on the Russian register, all or most of which likely carry just GPS. Foreign-registered aircraft flying in Russian airspace would be exempt from the rule.

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.

Today, most of us would probably rate cellphones, ATMs and the Internet as the three most useful modern gadgets we use regularly. We likely wouldn’t rank GPS up there, and maybe not even in the top 10. Yet without GPS, those three wouldn’t work too well, if at all, and neither would a host of other things that we depend on (reliable electrical power; banking systems; national and worldwide telecommunications, including air traffic control; and car navigation, to name a few). And with NextGen slowly approaching, aviation’s dependence on GPS will grow exponentially.

LightSquared signed an agreement yesterday with Javad GNSS to develop a system that it claims will eliminate related interference issues between LightSquared’s planned 4G broadband network transmitters and high-precision GPS devices.

Low-powered incoming GPS signals are allocated 1559-1610 MHz in the L-Band radio spectrum. The neighboring spectrum–from 1525-1559 Mhz–is allocated to other, equally low-powered, incoming satellite signals, such as Sky Terra’s. GPS receivers are open to signals above the blue line shown, but filter out signals below it, and require modification to accept Glonass.

With fresh evidence that LightSquared’s proposed wireless broadband network will cause widespread interference to GPS signal reception, principals of the industry Coalition to Save Our GPS went on the offensive today in a media conference call.

The French ministries of transport and defense have planned a global navigation satellite system (GNSS)/Loran C user information day on July 1 in Paris. “The information day is open to any person who has an activity related to the use of positioning or timing/synchronization information,” said the organizers. Focus will be on Loran C as a complement of GNSS.
