1. An over-the-horizon targeting system comprising:
- a satellite in earth orbit;
means for guiding said satellite to a position above a target;
a de-orbit rocket on said satellite which is ignited to decelerate said satellite;
a heat shield attached to said satellite to protect said satellite during de-orbiting;
a drogue chute which is deployed from said satellite to further decelerate said satellite to permit deployment of a maintaining means;
means for maintaining said satellite in said position above said target at an altitude which is above the limit of missiles that use aerodynamic control surfaces;
means for collecting information by said satellite about said target; and
means for communicating said target information to a receiver which is over-the-horizon from said target.

Abstract
The invention is directed to either a satellite or missile deployed to a high altitude location at a desired position above a target. Once at the proper position a drogue chute is deployed to slow reentry and then a high-altitude balloon or paraglider is deployed to maintain the invention above the target area. Once deployed, the invention utilizes onboard sensors to collect target information which is communicated to an over-the-horizon (from the target) receiver.

6. An over-the-horizon targeting system comprising:
-
a constellation of thirteen satellites in earth orbit to provide whole-earth coverage for said targeting system at a minimum constellation total weight, wherein a satellite in said constellation comprises; means for guiding said satellite; a de-orbit rocket on said satellite which is ignited to decelerate and de-orbit said satellite to a position above a target; a heat shield attached to said satellite to protect said satellite during de-orbiting; a drogue chute which is deployed from said satellite to further decelerate said satellite; a balloon which is deployed from and attached to said satellite to maintain said satellite in said position above said target at an altitude of at least 100,000 feet above sea level; means for sensing said target; means for powering said sensing means; and means for communicating information about said target collected by said sensing means to a receiver which is over-the-horizon from said target.
