The objective is to reduce drastically both the recurrent price and the mass of the platform equipment thanks to:
In order to address this business objective, the project is built on several work-packages grouped in 3 major themes :
The main hardware deliverables of the activity consist in
Prototypes of DPC G1 and High Speed Driver in plastic BGA packages are also deliverable items.
The main challenge for the programme is achieving the drastic cost reduction targets. What is usually requested for a new generation of equipment is a 30% reduction. The main technical challenges are the introduction of COTS and the introduction of new generation of power components such as GaN transistors. The increased proximity between power and low-level functions is also a challenge, as well as the thermal aspects.
The main benefits brought by the project are, from a commercial point of view, the increased competitiveness, through the reduced recurrent cost and mass.
The proposed product consists of the complete integrated multiplatform electronics of a satellite in a coherent and versatile family definition.
As such in the case of a TAS geostationary satellite the perimeter we intend to cover is the equivalent of the PCU + PFDIU + 3/4 PPU’s + SMU (including gyro), representing a total of 4 unit concepts and 6 or 7 individual units. With the new product we intend to reduce this to 2 unit concepts and 2 individual units for the core satellite power range of up to 15kW (14KW payload), or 2 unit concepts and 3 individual units for the maximum satellite power range of up to 30kW (25KW payload).
In the case of a typical earth observation or navigation satellite the perimeter we intend to cover is the equivalent of the PCDU + RTU + 2 PPU’s + OBC + GYRO, representing a total of 5 unit concepts and 6 individual units. With the new product we intend to reduce this to 1 unit concept and 1 individual unit.
In order to do so we are basing the approach on 2 mechanical concepts :
This figure provides an overview of the product perimeter in its low and medium power version. It gathers functions usually spread in different units, dealing with Power Conditioning, Power Distribution, Power Propulsion, Avionics functions.
The coverage of ARTES C&G contract is limited to TAS-B perimeter and to interface definition with other entities :
Refer to Product features.
The global Project plan is as follows:
The Architecture review has been held, providing a product tree and confirming the feasibility (mass, dimensions, electrical & mechanical performances, dissipations) of the modules, as well as firmware sizes and performances.
The target engines for Propulsion electronic has been extended to GIE.
An intensive breadboard test campaign has taken place, dealing with Power Conditioning, TM/TC and Propulsion.
In particular, the electronics necessary for the preparation of a coupling test with a RIT2X engine was successfully tested; the coupled test took place and provided very useful information.
Lots of new technologies have been evaluated in the frame of the project, as well as new components.
The project is completed, but it has paved the way to the design and development, followed by the Qualification of two units (ACE and HPU).
