On Thursday 18 August 2022, 5G!Drones project partners conducted final trials at Aalto University in the following scenarios: UC1Sc1 UTM, UC1Sc3 Logistics, UC3Sc2 IoT sensing. Involved partners: Aalto University, CAFA Tech, Involi, Frequentis, DroneRadar, RobotsExpert. In specific, our 5G!Drones project partners conducted final trials at Aalto University in the following scenarios:

• UC1Sc1 UTM
• UC1Sc3 Logistics
• UC3Sc2 IoT sensing

On August 15, partners conducted technical tests at Aalto University.

Aalto Uni. and CAFA Tech teams attended on site.

On August 16, Aalto Uni. radio network specialists reconfigured the 5G SA network and performed a series of tests with the modems.

On August 17, the CAFA Tech and Frequentis teams performed several tests so that the cellular drone could be clearly seen in the FRQ UTM.  Several technical tests performed on how the drone would be visible in different UTM systems.

On the morning of August 18, CAFA Tech and Aalto Uni. teams tested that WebPortal-1 and WebPortal-2 worked and then tested the operation of the UTM systems with the FRQ and DRR team. REX helped adding information about CAFA drone flights to the Aviamaps-I drone map used in Finland.

CAFA Tech team did preparations related to:

• prepared a CAFA 5G cellular drone with a built-in Quectel 5G modem and a 4K video camera. The 5G SA Uplink speed was approx. 6Mbps and used 720p SD video stream.
• set up the Qosium application for 5G QoS measurement: one Probe in Linux on the drone’s on-board computer and one Probe in the field laptop of the drone operator.

The purpose of CAFA Logistics’ automated flight was to use the Command and Control (C2) control system running on the 5G Edge server (Aalto server) and deliver a package of paracetamol tablets by automated flight. Since GPS is often inaccurate in urban conditions, the drone’s camera streamed the video image to the operator of the Logistics company so that it could be taken over manually if necessary.

Enablers used:

• CAFA Field C2 for logistics order
• CAFA C2 GIP (Ground station-Integration-Plugin) which sent drone telemetry data and KPIs to Kibana and telemetry to FRQ UTM system.
• CAFA 5G cellular PX4 drone
• Video streaming over 5G
• UTM system to share drones locations and flight plans
• Dashboard – on which screen different drone operators can stream their Ground Control Station (GCS) screens and different UTM systems.

After preparations and test flights, we performed the final flight by CAFA Tech:

• UC1Sc3 Logistics with UC1Sc1 UTM sharing the drone location in the UTM system.

Aalto Uni then started preparations for flight UC3Sc2 IoT sensing. The drone mission was planned in the C2 application, which worked at Aalto Uni. on the server. A 5G Nokia phone was attached to the Aalto drone, which generated Wifi and thus ensured the C2 application access over the 5G SA network to the Rasberry Pi on board the drone. Two IoT sensors were attached to the RasberryPi: a humidity sensor and a CO2 sensor.

After preparations and test flights, Aalto Uni. team performed two automated flights to measure air humidity and CO2:

• UC3Sc2 IoT sensing over 5G by drone.

Important note: CAFA Tech and Aalto Uni. the drones were both under 2kg and therefore it was possible to fly them in a densely populated area in the Open A2 category.
