The satellites will be strung along three medium-Earth orbits at 56 degrees inclination to the equator and will provide global coverage. The system should be operational by 2008 and the entire project is expected to (60) around 3.2 billion Euros (USD 3.6 billion).
D.
The European Commission has said Galileo will primarily be used for transportation technology, scientific research, land management and disaster monitoring. Galileo will provide two signals; a standard civilian one and an encrypted (编码) , wide-band signal (61) the Public Regulated Service (PRS). This second signal is designed to withstand localized jamming(干扰)and will be used by police and military services in Europe.
