The NADIR represents a valid opportunity for small missions since it embodies three basic characteristics: flexibility and performances matching a number of mission’s typologies, reduced recurrent costs, minimum 3 years lifecycle 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.
NADIR is wholly designed in accordance with an industrial rationale making wide use of Commercial Off-The-Shelf (COTS) components in order to optimize the costs/performances ratio. The COTS-based equipment and devices are properly adapted to operate in the Space environment. This solution the overall costs to be reduced by several orders of magnitude with respect to conventional satellites.
