		Egnos also provides integrity information, warning users if there is a problem with the GPS system and instructing them not to rely upon it.
		Egnos is dependent on GPS and if the Americans decided to resume degrading their GPS signals, Egnos would also deliver much poorer accuracy, although it would warn its users very rapidly that this was the case.
		Egnos is a joint project of the European Space Agency, the European Commission and the European Organisation for the Safety of Air Navigation, Eurocontrol.

	Navigation Systems (Site not responding. Last check: 2007-10-23)
		EGNOS (European Geostationary Navigation Overlay System) is a european programme destined to augment, with the aid of a dedicated ground infrastructure, the military navigation constellations GPS (USA) and GLONASS (Russian), to offer to the European civil aviation authorities the capacity of navigation with safety, integrity and very high precision.
		EGNOS enters into service at the middle of 2004 and will be used for the en-route phases, and non precision approach (category 1).
		EGNOS will permit civil aviation industries to keep a large part of their traditional navigation infrastructure (Beacon, etc) and permits the optimisation of air space, the time of flight, fuel costs, management of fleets and improve the overall operational safety in Europe.

	About EGNOS and WAAS
		The ground segment of the satellite based DGPS for EGNOS is a network of 34 monitor stations (RIMS; Ranging and Integrity Monitor Stations) which receive the corresponding satellites signals and transfer these to 4 central data processing stations.
		EGNOS was developed by the European commission mainly for civilian air travel, but also with emphasis on agriclutural applications in order to provide higher accuracies in the localization of positions than is attainable through GPS and so to promote precision farming.
		EGNOS will be integrated into GALILEO, the European satellite navigation system which will go into operation in 2008.

	Egnos Availability - Groundspeak Forums (Site not responding. Last check: 2007-10-23)
		EGNOS status is that the three GEO satellites have already been connected to the EGNOS computing platform and are currently being used for assembly, integration and validation tests of the system.
		Until EGNOS becomes operational we recommend to use the experimental signals broadcast by the ESTB (the EGNOS System Test Bed which is an experimental an independent version of EGNOS running since 2000 and developed to aid in the design phase of the EGNOS System.).
		It is foreseen that the EGNOS system will be declared available for non safety critical applications in Q2 2005 and will then undergo operational qualification activities towards its availability for safety of life services in 2006.

	EGNOS, Satellite navigation tracks rally cars » GPS NEWS and REVIEW
		To show the use of EGNOS in road applications, it was used for tracking the paths of cars competing in the German round of the World Rally Championship (WRC), which took place on 26 to 28 August 2005 in an area south of Trier.
		In each case the position of the cars according to GPS and according to EGNOS was visible simultaneously, allowing a comparison of the relative positioning accuracies of GPS and EGNOS to be made.
		EGNOS has now entered the ‘ramp-up’ phase of the Initial Operations; the geographic coverage of the signal will be expanded and the performance (accuracy, integrity, availability and continuity) will be further improved.

		EGNOS is the European Satellite Based Augmentation System (SBAS) for Global Satellite Navigation Systems (GNSS) and was designed to transmit wide area differential and ionospheric corrections, as well as associated integrity information, via geostationary satellites.
		Navigation receivers operating at or near ground level, however, may have a difficult time receiving the space-borne EGNOS signal, or signal in space (SiS), if something is obstructing the line-of-sight to the geostationary satellite broadcasting the correction signal.

		EGNOS — an ‘add-on’ designed to improve the accuracy of the US military-controlled global positioning system (GPS) — is expected to be fully operational later this year.
		EGNOS will also increase the availability of navigation information as its satellites are intended to be visible at all times, and provide ‘integrity signals’ which alert users to errors in GPS signals within six seconds.
		In the aviation sector, EGNOS is being considered as a complement to Navisat, a satellite system currently going through feasibility studies, which would cover MEA.

	View topic - WAAS/EGNOS/MSAS Information - GPS Forum
		I also believe that the Garmin units will show 2 EGNOS satellites leaving 10 available GPS channels, but in reality this should be more than enough, as you only need 4 at a minimum, and it is quite rare to get a lock on 10 anyway due to terrain and mask angles.
		As EGNOS claims, the time when you need the accuracy is during landing, but it is just at this time that you start to get masked by high ground around airports, particularly places like Aberdeen where I work.
		Until such time as EGNOS becomes FULLY operational, a lot of what we, as recreational users, might observe or interpret, may well be superceded when the system does finally 'switch on'.

		EGNOS will provide the information needed to use navigational signals from GPS and GLONASS satellites for such safety critical applications.
		The EGNOS receiver, which is more sophisticated than a standard satellite navigation receiver, will de-code the signal to give a more accurate position than is possible with GPS or GLONASS alone and an accurate estimate of errors.
		The EGNOS signal will be broadcast by two Inmarsat-3 satellites, one over the eastern part of the Atlantic, the other over the Indian Ocean, and the ESA Artemis satellite which is in Geostationary Earth orbit above Africa.
