Section: 5.2.1 Description
Content: Infrastructure may be deployed in certain regions to ensure the safety of UAS operations. The purpose of such an infrastructure would be to keep drones separated from each other and also from the few aircraft such as low flying helicopters with which they may need to share the airspace. The UTM may offer an Unmanned Aerial Vehicle Collision Avoidance System (UCAS) service. The primary scope of the 3GPP involvement in such a UCAS would be to provide accurate live positioning information into the UTM from the UAS or MNO, thereby offering a primary or complementary positioning solution able to allow an independent verification of the location reported by the UCAS, if applicable, and to ensure timely feedback from the UTM to the UAS. Most drones of a certain class already have collision avoidance systems on board. Such systems range is very wide from very poor to good – depending on size, quality, price of the drone and the know-how of the manufacturer. Active control from UTM is important and onboard systems can be used as a backup. Figure 5.2.1-1: Live data acquisition by UTM
