Uplink stations galileo biography

This information is embedded within the satellite signal itself. A second's clock error would put users km off target. Even the slight but continuous push of sunlight itself can affect satellites in their orbital paths.

So the ground stations placed around the world picking up Galileo signals perform radio-ranging in reverse on the satellites transmitting them, to pinpoint their current position and identify any orbital drift. Closing the loop in this way means that optimal performance can be maintained over time. They provide a wide bandwidth for the transmission of the Galileo Signals.

The names of the Galileo signals are the same as the corresponding carrier frequencies. Note that E5a and E5b signals are part of the E5 bandwidth. The Galileo performances are different for each service.

Uplink stations galileo biography: Galileo is Europe's own global navigation

GIOVE-A results are largely in line with specifications, which gives good confidence for the future of the programme and shows that Galileo is on the right track. This mission will continue the work started by GIOVE-A, using a satellite more closely representative of the design of those planned for the operational Galileo constellation. GIOVE-B will carry a high-precision passive maser clock - the most accurate clock ever flown in space - and will be capable of triple-channel transmission of navigation signals.

The satellite will be able to transmit a signal complying with a specific standard known as MBOCin accordance with an agreement reached only a few months ago by the European Union and the United States for their respective systems. Duringfour operational satellites - the basic minimum for satellite navigation in principle - will be launched to validate the Galileo concept with both segments: space and the related ground infrastructure.

Once this is achieved, the Galileo navigation signals will provide good coverage even at latitudes up to 75 degrees north, which corresponds to the North Cape, and beyond. The Galileo Control Segment GCS is responsible for a large range of functions to support satellite constellation control and management of Galileo satellites. The GCS provides the telemetry, telecommand and control function for the whole Galileo satellite constellation.

There are two redundant elements located at Fucino Italy and Oberpfaffenhofen Germany. However, when the navigation system of a satellite is not in operation during launch and early orbit operations or during a contingency use of the common standard TTC modulation allows non-ESA TTC stations to be used.
