GPFT (25784)
There is an emerging demand from private or public organisations to establish networks for private transmission of data. TETRA (Trans-European Trunked Radio) is the appropriate standard as defined by the green paper on mobile and personal communication. TETRA supports a common network with a high level of interoperability and roaming capabilities as well as the GSM standard.
This enables TETRA to satisfy all the communication needs of user groups such as:
The scope of the project is the development and the implementation on a microprocessor core, of the application layer and of the interface parts between the core, TETRA subsystem, GPS subsystem and display panel. This microprocessor will be utilised for the development of a portable terminal which will be used for fleet management and includes a GPS receiver block, a TETRA communications module as well as a control and display subsystem.
All the above mentioned areas have a strong need for distributed management of information. The companies in the consortium (SSA and OTE) are strategically positioned to commercially exploit this upcoming market through the implementation of a distributed philosophy portable terminal rather that a centralized one, in order to enable organisations to have multipoint command and decision making structures. This means that all information will be out in the field units. This feature is very important particularly in emergency cases where the units out in the field need all the data and relative positioning of all other units.
The partners have complementary expertise, SSA in GPS and fleet management, while OTE has experience with the TETRA standard.
TETRA is going to be used widely in the private mobile communications (as a better alternative to GSM). This system will enable the interested companies to implement their TETRA applications.
The project will evaluate alternative microprocessor cores which will provide all the necessary capacity to implement the communications protocol, fix transformations, corrections, navigational data calculations in quadruple precision and application layer functions.
The entire application will be specified in order to define the appropriate microprocessor core and specify the whole system architecture. This may be assured in collaboration with the local OMI support node which has the necessary required experience and will be a subcontractor to SSA. This collaboration will be also beneficial for both companies (SSA and OTE), since an existing working environment will be used from the OMI standards project, and will ensure best practice.
In parallel the software components for the protocol and necessary computational functions will be developed. Following the establishment of the microprocessor core system, the application software will be specified both in term of the full capability range as well as the demonstration level. The application level needs the most flexibility in order to provide maximum commercial exploitation depending on the client targets. The system must be provided so that minimal and low-cost versions could be produced for the low-end of the market as well as full power versions for the upper end as will be identified by the customer needs survey.
The application board which will host the GPS module, the application core and the other parts (display, RF interface etc.) will be ready along with the application software in order to validate the demonstrator by constructing a portable terminal for testing.
The results of the development and tests will be disseminated through the participation in conferences but also through the organisation of an event in the commercial chamber of Athens with the subject of fleet management systems.
