The project summarized here was conceived to support the definition of applications, products and user requirements, as well as the hardware design and ground processing design of a companion satellite mission which will carry aboard a "passive" radar working in tandem with the Argentinian L-band radar developed by CONAE and denoted as SAOCOM. The primary objective (i.e., science driver) of the SAOCOM companion satellite mission (SAOCOM-CS) is forest tomography, which will be carried out by exploiting small baselines between active and passive systems (order of km) changing with time.

Generally speaking DIAMS has been an opportunity to secure the feasibility of the IOD in technical, programmatic and financial terms. More specifically DIAMS has allowed to define the end-to-end mission concept for this IOD, covering the design of various associated segments : Space Segment (Payload, Platform), and Ground Segment. Both interest and programmatic aspects have also been consolidated.

- On the technical plane :
Both the requirements and the design of the system have been refined to validate the IOD concept :

Scope of the MImOSA2 (Monitoring Ionosphere Over South America to support high precision applications) study was to support high-precision GNSS based applications in South America, analysing, through an original method, GNSS data acquired by a dense network of 50 Hz receivers to assess possible improvements on positioning accuracy when ionospheric degradation is taken into account.

The activities carried out in the phase 0 deal with the mission concept and, in particular, with the interplanetary analysis and contributions to the mission requirements. The activities can be summarized as follows:
- study of the state of the art of Mars landers, with focus on issues such as the launcher, the interplanetary trajectory, the type of planetary approach, the design of the spacecraft, the layout, the mass and power budgets, the aerodynamic parameters, the entry, descent & landing strategy;
