Zipline, the world’s first national-scale drone
delivery service, has announced that the initial testing and diagnostic
flights of drones at the first emergency medical distribution centre at
Omenako in the Eastern Region is set to begin this month.
The revolutionary new service, which will begin operation in the 2nd
quarter, will use drones to make on-demand, emergency deliveries of
life-saving medications to over 2,000 health facilities across the
country.
In advance of launching its initial testing and diagnostic flights in
March, the Ministry of Health and Zipline have begun briefing the public
on the safety and security features of the company’s drone delivery
service.
“Using drones for emergency medical delivery, Ghana will be able to
save money and save lives,” said Dr. Anthony Nsiah-Asare, Director
General of the Ghana Health Services.
“No one in Ghana should die because they can’t access the medicine they need. Drone delivery will help us prevent that.”
“We look forward to working hand-in-hand with the Ministry of Health as
we begin emergency medical drone delivery in Ghana,” said Zipline CEO
Keller Rinaudo.
“An important part of that process is working with the community and
key stakeholders to better understand how the system works and all of
the work that’s gone into making it the safest at most reliable service
of its kind in the world.”
Zipline’s Safety System
Zipline’s drone delivery service is dedicated to expanding healthcare access and saving lives around the globe.
Health workers place orders by text message and receive their deliveries in 30 minutes on average.
Zipline’s drones both take off and land from its distribution centers,
requiring no additional infrastructure at the clinics it serves.
Deliveries are made from the sky, with the drone descending to a safe
height above the ground and air-dropping medicine by parachute to a
designated spot at the health centers it serves.
Because the company’s drones criss-cross commercial airspace daily over
both remote and populated areas on their way to deliver critical and
lifesaving medicine to people in need, the safety and reliability of
Zipline’s service is a top priority.
Recently, the United States Federal Aviation Administration announced
that it may require the U.S. commercial drone industry in future
regulation to adopt the kinds of safety features Zipline has already put
in place.
The company has taken many steps to ensure that it is operating the
safest delivery system of its kind in the world including rigorous
testing of flight software and aircraft hardware; flight operations
safety procedures; redundant inflight safety features; and modular
frangible design.
Rigorous Testing of Flight Software and Aircraft Hardware
The company works to improve the quality of its code and service every
day to make sure it is operating the safest and most effective drone
delivery operation in the world.
All software updates are first put through automated software and
hardware in the loop testing. Allowing advanced algorithms to assess how
the new code and aircraft would perform in the real world.
After passing through simulation testing, all new code is installed
onto drones at our state of the art flight testing facility in Northern
California, Codenamed Nest X, and pushed to the limits to validate
performance.
That process is repeated until the system and aircraft are ready to be deployed into global flight operations.
Flight Operation and Safety
Flight operators physically inspect each aircraft and use cutting edge
technology like computer vision during preflight checks to make sure
each drone is fit for flight.
Because Zipline’s drones fly autonomously along predetermined routes,
all of our flight paths are registered in advance with civil aviation
authorities.
Zipline is in direct communication with those aviation authorities so
that they know at all times when drones launch and where they are
flying.
Zipline’s sophisticated air traffic control system uses advanced
algorithms to make sure all drones in the air know where they are, where
they need to go.
Redundant In-flight Safety Features
Zipline drones are designed to automatically detect issues inflight and safely return to base for repair.
Each drone is equipped with redundant flight computers, motors,
communications systems, flight control surfaces, as well as redundant
navigation and power systems.
In the event of emergencies like severe weather, emergency requests
from air traffic control or unplanned flight operation issues, each
drone is equipped with a parachute that allows it to make an immediate
landing by slowly descending to the ground.
The drones use parachute landings at least once a week during the the
testing and diagnostic phase of beginning new distribution centers and
delivery routes or when the company decides to make deliveries in the
face of extreme weather to aid in emergency medical situations.
Modular Frangible Design
Zipline’s drones and its parts are designed to break on contact minimizing potential damage to things on the ground.
The drone’s core navigation, power, communications, and computing functions are inserted into the drone as a single unit.
That unit is housed within a carbon fiber chassis that is protected by
an outer Styrofoam shell, similar to construction of helmets.
The Styrofoam serves to protect anything on the outside of the drone as well as everything on the inside.
Damaged Styrofoam is quickly replaced allowing the drone to return to
service. The same is true for other flight modules, which include the
motors, wings, tail fins and power, navigation and communications unit.
If any one of those units experiences issues, it can be easily replaced
with a new one so that the aircraft can return to service saving lives
as quickly as possible.
Drone Delivery Service
The service will operate 24 hours a day, seven days a week.
The Ghana Health Service (GHS) has selected 148 lifesaving medical
products to be stocked at Zipline’s four distribution centers
nationwide.
Zipline will guarantee delivery of those products upon request to any of the thousands of health facilities served.
Each of the four distribution centers will be staffed by a team of 35
Ghanaian engineers and logistics personnel, equipped with at least 20
drones. Together, all four distribution centers will be capable of
making at least 600 on-demand delivery flights a day. The drones can
carry 1.75 kilos of cargo, cruising at 110 kilometers an hour, and have
an all-weather round trip range of 160 kilometers
