Inspection Public Security Delivery
First in Singapore to be approved for Beyond Visual Line of Sight (BVLOS) flights,
DroNet solution enables diverse applications such as facility or perimeter security, site
inspections, deliveries and more.

Introducing DroNet

The DroNet Solution is developed by ST Engineering for
Beyond Visual Line of Sight (BVLOS) flight operations toaugment the human operators through multi-UAVoperations, safer workflow automation, wide aerial datacollection and smart analytics.

The system is the first in Singapore to be approved by theCivil Aviation Authority of Singapore to conduct BVLOS
flight operations for surveillance and monitoring ofreservoirs in year 2019. Unlike the conventional drone
operation where a drone is operated within the pilot’s
visual line of sight, the BVLOS capabilities enable DroNet
to cover far greater distances to collect more data in lesstime.

The DroNet System has been deployed and operated inseveral applications such as fenceline patrol for intruder
protection, remote islands maintenance surveillance,industrial area security surveillance, water activities
monitoring at the reservoirs as well as shore to shipdeliveries. At present, the DroNet system has flown andclocked over 5000 hours of flight time.

FULL-PACKAGE SOLUTIONSThe DroNet solution includes thesmart analytics, anomaly alertingand data storage suites, making it
an end-to-end package.
BVLOS

Designed for Beyond Visual
Line of Sight flight operationsin urban environments.
SAFE

Incorporated with robust flight
management
featuresandredundancies for safe flights.
QUICK TURNAROUND

Rapid payload and batteryswapping mechanisms ensure
mission continuity.
SMART ANALYTICS

User is provided with the mostrelevant data to make wellinformed decisions.
DRONE AGNOSTIC

DroNet can be compatible foruse with other commercial, offthe-shelf drones.

Key Components

The DroNet solution comprises of the DrN series
unmanned aircraft (UA), the DroHub centralized
control station, the DroPort docking station and
DroConnect smart web platform forflightmonitoring, data analytics and real-time data
distribution. These sub-systems are interlinked
through the public/private 4G LTE network(provision for 5G in future), Radio Frequency (RF)and satellite communication to form the core
network infrastructure to provide robust
connectivity with cybersecurity protections.

DrN Series Drones
The DrN series UAs are autonomous Vertical
Take-off and Landing (VTOL) aircraft platforms
designed to meet the safety regulatory
requirements for BVLOS operations. The Flight
Control Computer (FCC) and the Guidance,
Navigation and Control (GNC) software aredeveloped by ST Engineering to customise several
safety features such as hardware and sensors
redundancy, automated failsafe handling features,
collision avoidance and flight template
confinement to meet diverse regulatory
requirements around the world for safe BVLOS
flight operations. The DrN Series UA has a payload
bay that can carry a basic 2-in-1 Electro Opticaland Infra-Red (EO/IR) camera. This allows the UA
to be used for day and night operation. The
payload bay is configurable to carry different
sensors for different applications.
