Sensors and Payloads: The Way Drones Make Money
When it comes to making money with your drone, it all comes down to the payload. Really, the drone is just a tool for putting the camera or another sensor into an area that was too expensive or prohibitive to do otherwise. This is where the drone industry gets exciting. What applications can you dream up using these cool technologies?
Cameras are the most popular type of payload and are typically at least one of the sensors onboard. They can be as small as a keychain like on FPV racing drones or large, cinema-quality cameras with complex gimbal set-ups weighing tens of pounds. Some aircraft can even handle two cameras and have one for pilot orientation and the other geared for a specific purpose such as low light operations, 360 degrees or with zoom capabilities.
This highly versatile piece of tech can be used in agriculture, surveillance, accident scene assessment, wildlife tracking, search and rescue, infrastructure assessments for heat loss or for machinery diagnostics for heat build up.
Synthetic Aperture Radar
The details of how this impressive technology works are a bit beyond this post but the ultimate result is that this sensor can “see” through cloud cover, foliage, even structures. Since it uses a lot of power, it’s currently on large aircraft and satellites and primarily used to do assessments and monitoring of ice caps, earthquakes, resource monitoring, intelligence acquisition etc.
Multi and Hyper Spectral
Multispectral imaging such as NDVI or Normalized Difference Vegetation Indexing is used in precision agriculture. These sensors read bands of frequencies reflected off the surface below and crunch that data through software programs. This data provides insights into crop health, land management and hundreds of applications outside of agriculture like ecology, oil and gas, oceanography and atmospheric studies.
Chemical/Biological “Sniffer” Sensors
Using spectrometers, drones can detect airborne biological information for atmospheric analysis, helping meteorologists make better forecasts. Through the aid of algorithms, these sensors can also detect abnormalities in the cases of chemical attacks or gas leaks.
Covering everything from spraying pesticides to dropping off your Amazon order, releasable payloads are a huge opportunity. Think Hunger Games style parachuting supplies or aid to people in need. However, regulatory bodies are understandably restrictive when it comes to dropping things from aircraft. Once safe and reliable systems enable beyond visual line of sight flying and clean releases, we can expect to see this side of the industry grow beyond the current applications into areas like aerial pharmacies.
Providing asset and inventory tracking, airborne RFID scanners allow drones to scan areas in a repeatable, cost-effective manner. Anything you’ve attached your tags to can be traced by simply flying overhead.
Similar to RFID scanners, drones can pick up on and follow tagged equipment, people or assets. New technology even allows tracking via camera image, rather than needing to provide a pre-established tag. Although there are limitations, this is a promising avenue for the future.
Although there are some extra requirements before you’re allowed to sling a laser around the skies, laser payloads like LiDAR enable surface mapping through foliage, clouds and ground cover
