Improved Scenario

The scenario starts with the customer buying a package in 2025 from the best-selling company in the Eindhoven. The customer lives in the so called “Parklaan”. Within 20 minutes after payment, the drone with the package is in a radius of 100 meters of the destination.

When the drone is nearby it switches to a more accurate way of orientation, to find the exact location of the front door where it needs to be. The customer lives in a flat, so because of laws he still has to come out of the apartment to the front door of the building. A few years back this was possible, but to many drones got into flats so it could not be handled anymore. This is why the drone is not allowed to go into buildings.

While the drone evades 2 birds and 10 rocks (that children threw) and 1 other drone it flies smooth and quick to the front door of the flat. The customer gets 2 minutes before the drone arrives a message on his phone that the drone arrived and he comes to the door. At this moment the company is still accountable for the package and this is staying this way until the customer accepted the package. The customer can identify himself by showing his member card from the company or by showing the QR-code of the order together with his id-card. After the drone verified this data with the data that is attached to the package, the package can be released. The customer has to tell if he wants the package on the ground or in his hands and the drone easily does so. If the customer has the package, the drone verifies that it is done and it can leave after exactly 26 minutes after payment.

While gaining altitude, a person tries to grab the drone. The drone can react fast and can just get away of this persons hands. If it would be grabbed, the drone makes pictures of the person and sends all the information to the headquarters. The headquarters would immediately call the police and the special drone squad will track the robber down. Luckily this time is not that time, but just to make sure the drone makes a picture. This picture is only kept for several months for evidence. Now the drone is at a safe distance from bad people, it can return back to the base. It is still not allowed to go over gardens, which is a rule since the beginning of the drone-age. The drone just uses the air above the streets, just as it is told to do.

Movement of the drone

Location the drone

An important factor of delivering a package is that it gets to its place of destination. There are several systems to provide this information. The most used and best know is the Global Positioning System (GPS).

A GPS-receiver uses a least four different satellites, in a direct line of sight, to determine its location. There are two different kinds of GPS: civilian GPS (SPS) and military GPS (PPS)[1]. The online difference between these two types is the frequency it uses to send out the signal. The GPS-signal can be received on the whole earth and an internet connection isn’t needed. The accuracy of the location determined with GPS depends on some factors. The most important factor it the quality of the receiver.

Since GPS uses time to calculate the position of the receiver and the receiver isn’t connect all the time to an atomic clock, the less a clock tends to drift the higher the accuracy will be of the calculated position. Most of the time it’s safe to say that, on solely using GPS, the position determined has an accuracy of 15 meters.

A newer system, and used alongside the GPS-system, is the Global Differential GPS System (GDGPS)[2], Which is developed by the Jet Propulsion Laboratory. This system uses ground based sending station to send out the error of the position of the satellites of the GPS-system. This improves the position determined with GPS from 15 meter to 10 centimeters.

Finding the costumer (and the correct house)

Delivering to a front door which can't be reached

It may be possible that the drone can’t reach the front door of the costumer. This can happen when, for example, the costumer lives in an apartment complex where the front is covered or the front door is at the inside of the building. Since the drone needs to land and can’t enter the residence of the costumer, the delivery can’t be done through the window.

At the moment deliveries in apartment buildings, done with real humans, have different solutions for this problem. Some companies expect the costumer coming down to the front door of the building, other companies let the mailman go to the front door of the apartment. The first may be a solution for the drone delivery problem, the later isn’t.

Communication with the costumer


Rules concerning drones from the Netherlands, category light (4-150 kg).


  • Stay under 120 meters
  • Keep direct sight on your drone during the whole flight
  • You can only fly during daylight, with an environment that allows for clear sight
  • Avoid people and animals
  • It is not allowed to fly above cities, towns (150 m), railways, roads and docks (50 m)
  • Stay away from airfields
  • No flying within no fly zones


As a company it is obligatory to have a ROC (RPAS operator certificate) for flying drones. (Since 2015 1st of July)[3]. This means the following:

  • The drone pilot has a certificate for flying drones
  • The drone has a BvL (bewijs van luchtvaardigheid, ‘prove of airworthiness’)
  • You are in the possession of an approved operations manual


  • Keep direct sight on your drone during the whole flight
  • You can only fly during daylight, with an environment that allows for clear sight
  • Other airspace users will have precedence at all times

Concerning privacy

Besides the normal privacy rules[4]:

  • Not allowed to (systematically) gather data about people, including public
  • Not allowed to use advanced camera like infrared, night-vision, heat-camera, camera with built-in analytic techniques or cameras which do nothing but monitor
  • Not allowed to gather information that is publicly published

Filming through windows or looking in buildings is direct infringement of privacy.
