Benefits of technology

The technical effect of this patented technology is that it allows multiple spaceships to be connected together accurately by creating a tethered connection.

Problems solved by technology

This patent describes a type of space mission called Tilted Space Interference System (TSIS). It uses tethers to connect space objects together. However, there are technical problem addressed in this patent where it has limitations due to tether sagging and instability caused by external loads.

Embodiment Construction

[0017]An embodiment of the invention is described with reference to the figures using reference designations as shown in the figures. Referring to FIG. 1, a based spacecraft and a tether spacecraft are initially juxtaposed in a towed position. The base spacecraft includes a stand-off reel drive motor for extending and retracting a flexible semi-rigid stand-off. A top tether drive motor and a bottom tether drive motor are used to release and take-up a tether extending between the top and bottom drive motor and along the standoff, around a pulley couple to the distal end of the stand-off, and back again along the stand-off. A clamp is used to fasten the tethered spacecraft to the tether. The claim is preferably a nut and screw fastener for coupling to the tether and is preferably bolted to the tethered spacecraft. In a stowed position, the stand-off is fully retracted so as to position the pulley to an interior position within the two spacecraft, and in the preferred form, to position th

Abstract

A tethered spacecraft is tethered to a base using a semirigid stand-off and a moving tether operated as a belt drive and operated in tension so that the tethered is precisely positioned in tension from the base spacecraft.
