Summary of the FLOAT-2 mission data. Several long-range detections were made early in the flight (299 km to 528 km) with the transmitting aircraft between 0.25 and 0.63° above the horizon. Given the potential for signals passing this close to the horizon to be obstructed or refracted, it is possible that these signals did not propagate by line of sight.
