The gravatronic radar uses specialized sensor arrays involving gravitons. The entire system is designed to actually charge and release a graviton burst in a 360-degree sphere from the ship. The graviton wave would then travel until it hits something, which would then register on the detectors of the Gravatronic Radar. Black Holes and other gravitational anomalies have been theorized to disrupt the Radar.
A Station Gravatronic Radar is the largest of its type and has the longest range due to accessible power sources. It's average range is normally 50 Light-Seconds or 14,989,622 kilometers.
