system that supports wide-area or regional augmentation through the use ofadditional satellite-broadcast messages. Such systems are commonly composed ofmultiple ground stations, located at accurately-surveyed points. The ground stationstake measurements of one or more of the GNSS satellites, the satellite signals, orother environmental factors which may impact the signal received by the users.

The GLONASS System
Currently, the only other fully functional GNSS, GLONASS, is developedand maintained by the Russian government. It was created in 1976 andhas undergone various transformations and restorations. In late 2011,the system was restored to its complete capacity of 24 satellites, whichare located on 3 orbital planes with an inclination of 48° from theequator. The Russian government has been promoting the civilian useof GLONASS, requiring the production of GLONASS compatible vehiclesby car manufacturers starting from early 2011. Like GPS, GLONASStransmits on L1 and L2 bands.
The GALILEO System
Galileo is a global navigation satellite system (GNSS) currently being built bythe European Union (EU) and European Space Agency (ESA), intended forcivilian use only. A defining characteristic of Galileo is that, unlike GPS andGLONASS, it was conceived and developed and will always remain undercivilian control. While European independence has been a key goal behindthe creation of the new system, Galileo is nevertheless 100% interoperablewith GPS and GLONASS, making it a fully integrated new element in theworldwide global navigation satellite system, a powerful cornerstone that willallow more accurate and more reliable positioning, even in high-rise citieswhere buildings can obscure signals.
Galileo will form an important element ofMEOSAR, “the Medium Earth Orbit Search andRescue system” and thus a key contributor toCOSPAS-SARSAT, the international satellite-basedsearch and rescue distress alert detection andinformation distribution system .
Galileo Current and planned signals Structure
E1 (1559~1594 MHz),
E6 (1260~1300 MHz),
E5a (1164~1188 MHz)
E5b (1195~1219 MHz).
The search-and-rescue downlink signal is transmitted by the Galileo satellites in the frequency range of between 1544 and 1545 MHz
The European Satellite Navigation System & EGNOS
EGNOS is the first European SBAS, which enhances the performances of the existingsatellite navigation systems (GPS and GLONASS).EGNOS is currently operational: the EGNOS Service Provider has been certified during
July 2010
EGNOS entered into operation for Safety of Life in March 2011.
EGNOS signal is transmitted on the same signal frequency band and modulation asthe GPS L1 (1575.42 MHz) C/A civilian signal function. While the GPS consists ofpositioning and timing signals generated from spacecraft orbiting the Earth, thusproviding a global service
EGNOS provides correction and integrity information intended to improve positioningnavigation services over Europe.
EGNOS could easily spread the facility of its service to the African region with someadaptations and the sole installation of ground facilities (stations) on the Africanterritory.
The Benefits of EGNOS in Africa in Maritime, and other user Domains
EGNOS services have positive impacts in maritime applications and transportdomains, such as land management surveying, maritime safety along the shoresand in approaching ports, rail transportation, and in the oil and mining industry.
Enabling RIS (River Information Systems) and increasing efficiency and safety withrespect to the current situation, SBAS could contribute to the development ofAfrican inland waterways
GNSS Applications in Inland Waterways
• Fairway Information Services (FIS)“one-way information from shore to ship”by standardized Electronic Navigational Charts (ENC)
• Traffic Information Service “ TTI & STI”
River Information System (RIS)
River Information Services' (RIS) main tasks consists in the electronic position recording of all vessels in the system and their display on an electronic navigational chart, known as the Inland ECDIS.This task is achieved via the efficient use of “satellite positioning”, radio data transmission and adjusted visualization.
• Inland ECDIS
• Inland AIS
• Inland AIS on Aids to Navigation (AtoN)“this virtual A toN’s Nav-aids may be displayed on an ECDIS chartand might be used to mark a wreck, or to mark a fairway in poorvisibility conditions where buoys won’t last, and to mark adangerous area or no go areas”.
Nile riverFacts about the Nile river: The Nile is a major north-flowing river in
northeastern Africa. The Nile Basin covers about 10 per cent of the
African land mass and hosts nearly 20 per cent of the African population
River Nile is one of the oldest rivers in the history Nile receives its name from the Greek “Neilos”,
which means a valley or river valley It is approximately 6,853 km long, 3126 km in
Egypt Nile is actually longer than South America's
Amazon.
Importance of NAVIGATION IN EGYPT'S NILE

In less than a decade, 600 million tons of goods will need to be transported inside Egypt annually

Navigation Problems in the river Nile
Lack of experience among boat navigators The absence of the suitable navigational aids and landmarks change in the level of the river bed, the navigational information of the
channels is not well defined, and continues change of the water level“the variation of water levels, along the River Nile from Old Aswan Damto Delta Barrages are the significance problems that faces the navigationin river Nile.
Improvement sequences of river Nile navigation
Defining the shore line of the river. Production of River Navigational Charts. Installation of aids to navigation, which
includes; Watermarks and land mark Institution of control centers.
Establish continuous follow system upon the navigational channels
Creation of navigation traffic system. Creation planes for the operation of the
navigational channels.
GNSS Applications for Inland Waterways
Global Navigation Satellite Systems (GNSS) technology has evolved over thepast years and allowed for expansion into a wide range of sectors, includinginland water navigation. It analyses the factors that are driving of GNSSapplications in inland water navigation and tracking.
The demand on the GNSS applications “RIS” is highly recommended innavigation and tracking in Egypt's Nile, due to its importance, representinga huge economic gain in terms of Nile transportation services provision;contribute to solving the problem of traffic overcrowding and reduce roadsaccidents, saving lives, and leaving the network of main roads for privatecars .
