Abstract
Various techniques can be utilized to emit a signal away from the entity generating the signal or otherwise reduce the signature in the electromagnetic spectrum of an entity in communication with another entity at a distance. Static and mobile air, land, and sea-based assets can be used with combinations of physical, wired, and wireless interactions.
Claims20
An unmanned aerial vehicle comprising:
- a navigation system configured to:
- calculate a position in space based at least in part on an encryption key, and
- cause the aerial vehicle to travel to the position at a specified time, wherein the position facilitates reception of a low observability signal from a remote emitter;
- a signal receiver configured to receive a low observability signal from the remote emitter at the position at the specified time, wherein the low observability signal includes a transmission payload;
- and
- a transmitter configured to retransmit at least the transmission payload.

A method, comprising:
- calculating a position in space based at least in part on an encryption key, and
- causing an unmanned aerial vehicle to travel to the position at a specified time, wherein the position facilitates reception of a low observability signal from a remote emitter;
- receiving, using a signal receiver of the unmanned aerial vehicle, a low observability signal from the remote emitter at the position at the specified time, wherein the low observability signal includes a transmission payload;
- and
- retransmitting, using a transmitter of the unmanned aerial vehicle, at least the transmission payload.
