Nadir Platform 2
The NADIR represents a valid opportunity for small missions since it embodies three basic characteristics:
- Flexibility and performances matching a number of missions typologies;
- Reduced recurrent costs;
- Minimum 3 years Life-Cycle in LEO orbits.
Flexibility is provided by the modular design of the nanosatellite, which is made of two units that can be integrated separately:
- The Service Module, containing all the subsystems required for the in-orbit satellite operations;
- The Users Module, which shall host all the Payload's subsystems.

Micro/nano/pico-satellites, weighing less than 50 Kg, have become important tools for space utilization, as they have the strong merits of low-cost and quick development, which may encourage new user to exploit new ways of space utilization.
Applications for nano/microsatellites are diversified, with increased forecast for Earth observation and remote sensing missions. The IMT Platforms cover the mass range from 3 (CUBESAT 3U) to 30 Kg (NADIR).
