Full deployment and operations phase (phase E2).
The development and validation phase consists of the design, development, and
in-orbit validation (IOV) of the so-called IOV system configuration. This configura-
tion consists of a limited number of GALILEO satellites with the associated Ground
Segment and initial operations. Following successful completion of this phase, addi-
tional satellites and Ground Segment elements will be deployed to achieve the
so-called FOC system configuration leading to FOC.
The activities contained under phases C/D/E1 address the following:
•
Overall system engineering, verification, and operations;
•
Development and IOV of the Space Segment, including the launch of a proto-
type flight model satellite followed by three flight model satellites, IOT, and
initial operations;
Development and validation of the GCS, including in particular S-band
TT&C stations, associated communications network, and satellite control
facilities within the GCC, including deployment and initial operations;
•
Development and validation of the GMS, including in particular L-band GSS,
C-band ULS, associated communications network, processing, and mission
control facilities within the GCC such as deployment and initial operations;
•
Development of test user equipment in support of system experimentation
and validation.

The configuration of the GALILEO system during IOV is scaled down from the
full-operational configuration. Figure 10.17 shows the configuration for the IOV
GALILEO system.
