The most important consideration is the need for the receiver’s clock to be perfectly synchronized with the satellites to allow for accurate time calculations. There are a lot of sources of errors and uncertainties which the system needs to address. However, this is a very simplistic description of the mechanisms behind GPS technology. Using the data from multiple satellites, the accurate location of any GPS receiver on Earth can be deduced. These signals are sent as radio waves that travel at the speed of light.īy calculating the time it takes for the signal to arrive from satellite to receiver, the distance between the two can be determined. Each of the satellites in the network continuously transmits time-stamped signals which can be received by GPS receivers on the ground. The location of any GPS receiver can be accurately determined using the concept of triangulation. Many mid-range to high-end drones allow for redundant GPS and GLONASS navigation, just in case one of the other fails due to poor signal coverage. It’s not unusual for a GNSS receiver to provide access to more than one of these GNSS networks. The other popular alternatives include the Global Navigation Satellite System (GLONASS) owned by Russia, the BeiDou by China, and the Galileo by the European Union.Ĭollectively, these satellite navigation systems fall under the Global Navigation Satellite System (GNSS). ![]() To be more precise, the GPS network is owned by the US government and is being operated by the US Air Force. It may come as a surprise to some, but the GPS network is only one of many satellite-based navigation systems that are currently operating. Anyone with a GPS receiver can access the GPS network – this receiver is the one found in our phones, cars, fitness wearables, and drones. Central to this system is the network of up to 32 satellites orbiting the Earth, although this number can have slight variations when older satellites are retired or replaced. ![]() The Global Positioning System (GPS), originally knowns as NAVSTAR GPS, is a satellite-based navigation and location system. How exactly does a drone use GPS technology? What is GPS anyway and how does it work? What is GPS? This GPS is no different than the ones used in car navigation devices or your smartphone. One of the technologies that empower many of the drone’s more useful functions is onboard GPS. Between the various sensors, motors, propellers, cameras, and transmitters inside a drone, a drone truly is a marvel of modern engineering that has become accessible to the common consumer. ![]() 3D Insider is ad supported and earns money from clicks, commissions from sales, and other ways.ĭrones can do what they do through a complex system of interconnected parts working together.
