A modular system for the shelter, transport, positioning and elevation of sensors including a first module (A, I) and a second module (B, II) side by side and cooperating with each other. The first module operates as a functional block with vertical translation and the second module operates as a functional block with rotation/horizontal translation. Each module comprises a lifting means and together the two modules enable a sequential lifting of the sensor means in two phases. In one embodiment, there is also a third interfacing module (C) responsible for the switching of functional blocks included in the first and/or second module.
