The main objectives of the DENISE Project are:
The high level system architecture of the DENISE system is shown in the figure below. It includes all elements that will be found in the targeted system, as well as the interfaces among them, including the interfaces to existing 2G/3G and IP terrestrial networks.It is also indicated that all elements except the NCC can appear several times in the system.
The different terminals are shown as part of the user segment; the forward and return Complementary Ground Components (also referred to as repeaters and collectors) are grouped under the complementary ground segment, which also includes the so called gap fillers (GF), which are ground elements that interact with the terminal but are not managed by the service operator.
Even if the baseline design will be done considering the features of the W2A satellite, the system shall be envisaged so as to be also compliant with potential future satellites. The ground segment is composed by the hub (or hubs) together with the NCC, both interfacing the service centres. In the targeted system, all network elements (except the satellite) can have direct interfaces to 2G/3G or IP terrestrial networks.
The DENISE Project is organised in two phases:
Fraunhofer IIS, Germany
Indra Espacio, Spain
MBI group, Italy
Space Engineering, Italy
