The Galileo Statelite Has Made The World More Safer and Predictable
The Galileo has guaranteed the availability of services under all but the most extreme circumstances and has continued to make the world more safer.
The EU’s Galileo Statelite Navigation Program is the third such deployment in space after the US Global Positioning System (GPS) and the Russian Global Navigation Statelite System(GLONASS). According to the European Space Agency (ESA), all three systems are working together in a coordinated manner so that a position anywhere can be determined with any receiver picking signals from any combination of statelites belonging to any of the three systems. The total project cost of the Galileo has been estimated at 3.4 Billion Euros and the EU insists, the purpose of the Galileo is purely for civil objectives.
It comprises a constellation of 30 Statelites of which 27 are operational while three are spares which have all been positioned in three circular Medium Earth Orbit planes that stand at 26, 616 km above the the earth and at an orbital plane inclination of 56 degrees with reference to the equatorial plane.
Galileo currently provides services for mass market applications and signals for Timing and positioning free of charge to the EU and the rest of the world. But added value market applications requiring higher performance is offered by Galileo at a fee.
It also offers safety services in world transport applications where lives could be endangered if the performance of the navigation system was degraded without real time notice. Galileo has a world wide high integrity level for safety-critical applications that has greatly improved global air transport safety.
Galileo is also duty bound to offer Public Regulated Services which is primarily controlled by groups such as the police, fire ambulance services, military and Customs. Public Regulated Service is required to be operational at all times and in all circumstances with Civil bodies regulating access to the encrypted services.
On matters of Search and Rescue services, the Galileo currently assists EU countries to receive real time reception of distress messages by precise statelite locations and with multiple statelite detections to overcome any topographical obstructions.
Without the Galileo and other existing Navigation systems, the world would probably be very unsafe to live in.
