Abstract
A motor-drive device for sensors around a spherical electromagnetic lens, for example a Luneberg type lens using in a system of transmission and/or reception, comprises, for each module, at least one piezoelectric motor rigidly connected to the module, the module moving in the vicinity of the surface of the lens by the reptation of the piezoelectric motor on this surface. The disclosed device can be applied especially to receivers and/or transmitters carrying out multiple-satellite tracking, for example in the field of communications by orbiting satellites.
Claims29
A motor-drive device for transmission and/or reception modules in a receiver and/or transmitter with spherical electromagnetic lens, the device comprising, for each module, at least one piezoelectric motor rigidly connected to the module, the module moving along the surface of the lens by the reptation of the piezoelectric motor on the surface of the lens,
- wherein the module is capable of moving across the surface of the lens in at least a first direction and a second direction, the first direction being substantially perpendicular to the second direction.
A motor-drive device assembly for use with at least one of a receiver and a transmitter with spherical electromagnetic lens, said assembly comprising:
- at least one of a transmission module and a reception module;
- and
- a piezoelectric motor connected to the module,
- wherein the module is adapted to move along a surface of the lens by reptation of the piezoelectric motor in at least a first direction and a second direction, said first direction being substantially perpendicular to said second direction.
