GPAR-RMS Overview
 Conceptual image of the GPAR-RMS concept Personnel within the Center for Unmanned Aircraft Systems Research, Education, and Training at the University of North Dakota have been pursuing a two-pronged approach to meeting this challenge. These involve sensing aircraft using ground-based radars, combining that information with those from cooperative aircraft reports, and providing the required information to UA pilots [the Ganged Phased Array Radar-Risk Mitigation System (GPAR-RMS) which is a form of Ground Based Sense and Avoid (GBSAA)]. The other approach is to use sensors onboard UA to identify and avoid other aircraft [Airborne Sense and Avoid (ABSAA)]. The GPAR-RMS concept uses three phased array radars stationed in a triangle to monitor an operational airspace simultaneously. The use of three radars increases system redundancy (which increases safety), probability of target detection, and target classification. Other systems used with the GPAR-RMS include ADS-B, GPS, and transponders. The combination of all these sensor data provide the pilot with a true air picture of all the targets that are a possible risk to UA operations. This system has been developed and deployed several times with the ScanEagle system. A 40 ft fifth-wheel trailer was acquired for use as an operations center for both the GPAR-RMS and the ScanEagle GCS. Although the GPAR-RMS is still in a testing phase, it has proved to be extremely valuable during these deployments.
