From the Ted Talk by Andreas Raptopoulos: No roads? There's a drone for that
Unscramble the Blue Letters
Let's look at each one of those technologies in a bit more detail. First of all, the UAVs. eulatlnevy, we're going to be using all sorts of vehicles for different payload caiiepctas and different ranges. Today, we're using small quads. These are able to transport two kilograms over 10 kteelrmois in just about 15 minutes. Compare this with trying to trespass a bad road in the developing world, or even being sctuk in traffic in a developed world country. These fly autonomously. This is the key to the technology. So they use GPS and other sensors on barod to navigate between ground stations. Every vehicle is equipped with an automatic payload and battery exahcgne mechanism, so these vehicles ngaitave to those ground stations, they dock, swap a battery automatically, and go out again. The ground stations are lctaoed on safe locations on the ground. They secure the most vulnerable part of the mission, which is the landing. They are at known locations on the ground, so the paths between them are also known, which is very itorapmnt from a riblitialey pprvstcieee from the whole network. Apart from fulfilling the energy rteqremneuis of the vciehles, eventually they're going to be becoming commercial hubs where people can take out loads or put loads into the network. The last component is the operating system that manages the whole network. It mnotiors weaehtr data from all the ground stations and optimizes the retuos of the vehicles through the system to avoid adverse weather conditions, avoid other risk factors, and optimize the use of the resources throughout the network.

Let's look at each one of those technologies in a bit more detail. First of all, the UAVs. Eventually, we're going to be using all sorts of vehicles for different payload capacities and different ranges. Today, we're using small quads. These are able to transport two kilograms over 10 kilometers in just about 15 minutes. Compare this with trying to trespass a bad road in the developing world, or even being stuck in traffic in a developed world country. These fly autonomously. This is the key to the technology. So they use GPS and other sensors on board to navigate between ground stations. Every vehicle is equipped with an automatic payload and battery exchange mechanism, so these vehicles navigate to those ground stations, they dock, swap a battery automatically, and go out again. The ground stations are located on safe locations on the ground. They secure the most vulnerable part of the mission, which is the landing. They are at known locations on the ground, so the paths between them are also known, which is very important from a reliability perspective from the whole network. Apart from fulfilling the energy requirements of the vehicles, eventually they're going to be becoming commercial hubs where people can take out loads or put loads into the network. The last component is the operating system that manages the whole network. It monitors weather data from all the ground stations and optimizes the routes of the vehicles through the system to avoid adverse weather conditions, avoid other risk factors, and optimize the use of the resources throughout the network.
