Module exchanger systems

Abstract

A module exchange system including a module manipulator mechanism for use in manipulating modules between a module storage magazine and a satellite. The manipulator includes an adjustable terminal device which is capable of accommodating satellite modules of different geometrical proportions and a latching probe mechanism for releasably latching the modules with respect to the satellite and the module manipulator. The module manipulator is designed for movement along three mutually normal axes and is rotatable about one axis. The adjustable terminal device comprises two pairs of mutually crossed angularly adjustable arms having fingers at their outer ends for securing the modules, the arms being mutually angularly adjustable with respect to one another and telescopic so that the positions of the fingers may be adjusted to be received by modules of different proportions. The satellite is provided with passive latching probes having heads and each module has active latching members which have one end movable into and out of latching engagement with a head of a latching probe to engage the probe to releasably secure the module with respect to the satellite, the active latching members return to earth with the module for servicing. Active latch operators are mounted in the module manipulator to secure and release the module with respect to the satellite, the latch operators remaining with the manipulator to be returned to earth with the shuttle for servicing.
