Abstract
Satellite echoing for geolocation and mitigation of Global Navigation Satellite System (GNSS) denial are provided herein, where an example method comprises: transmitting, by a processing device, an echo message along a communication path having a communication satellite and a target device with an unknown distance to the communication satellite; receiving, by the processing device, a return of the echo message from the communication satellite over the communication path; determining, by the processing device, a time of travel of the echo message associated with only a single traversal of a portion of the communication path that is between the communication satellite and the target device; calculating, by the processing device, a distance between the communication satellite and the target device based on the time of travel; and performing, by the processing device, one or more actions based on the distance between the communication satellite and the target device.
