IOD of techniques and technologies for M2M Telecom missions

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 :

Disposal strategies analysis for MEO orbits

The Medium Earth Orbit (MEO) region, home of the operational Global Navigation Satellite Systems (GNSS) GPS and Glonass, is becoming more and more exploited with the advent of the European Galileo and the Chinese Beidou constellations, both in their build-up phase. The sensitive applications of the navigation satellites and the absence of any natural sink mechanism, such as the atmospheric drag, call for a careful debris prevention policy able to preserve the MEO environment, avoiding in the future the problems now already faced by the LEO and the Geostationary Orbit (GEO) environments.

Collaborative calibration of MEO GNSS signal biases based on LEO satellites GNSS-BICS

GNSSBICS is a feasibility study carried out in the frame of the ESA’s General Studies Programme (GSP)
by DEIMOS-Space, Deimos-Engenharia and ESA.
This activity investigated what G/S infrastructure would be necessary to develop a System, named as GNSS-BICS (GNSS Bias Calibration System), in charge of providing, under demand, the GNSS MEO S/C SISBAF (Signal-In-Space Biases Amongst Frequencies), from GNSS observations gathered by GNSS multi-frequency receivers on-board LEO satellites (potentially from different missions).
