Drones provide unique capabilities that are leveraged by emergency service providers all over the world. They are already saving thousands of lives through participation in various public emergency and safety operations.

The 2020 COVID pandemic has accelerated the adoption of drones for public safety. When humanity was facing a worldwide lockdown, authorities in India used drones to monitor cities and enforce social distancing norms. Read the full case study on how an Indian startup helped authorities in the state of Gujarat to use drones via the country’s first drone command center.

When it comes to public safety, drones are used in a variety of use cases. But there is this one use case that catches peoples’ attention since the benefits are pretty straightforward. The use case we are talking about is search and rescue.

What is search and rescue?

Search and rescue (SAR) is a subset of public safety operations and involves activities revolving around finding missing people. It generally comes under the purview of the fire department in most countries. In the US, private SAR teams also exist; for example, Texas EquuSearch is a not for profit organization dedicated to search and rescue operations.

In 2019, a hiker got trapped on a ledge somewhere in the Snowy Canyon State Park, Utah. The mountain search and rescue operation happened at night using drones. SAR drones were used as a light source by the rescue team to locate the hiker. Similar to this, there are thousands of stories of how drones helped save precious lives.

Advantages of Drones for Search and Rescue (SAR)

Search and rescue operations are fairly difficult and unpredictable, unlike other public safety operations. These two factors play an important role in the overall outcome of a SAR mission:

  • Time: In most SAR missions, the missing person is trapped in a life-threatening situation, where the person has less time. So it becomes important for rescuers to find the person at the earliest.
  • Terrain: SAR missions outside human establishments can face challenging terrain in the form of a snowy mountain, rainforest,  etc. which might slow the entire operation.

Here are some of the reasons why SAR teams, all over the world, are using drones to overcome challenges in their work:

  • Drones are fast: Compared to ground-based vehicles, drones can reach a location a lot faster; even reach inaccessible places. For example, in the Czech Republic, there is an agency called the Mountain Rescue Service of the Czech Republic that uses drones to find missing people trapped by an avalanche.
  • Situational awareness: Drones provide cheap, fast access to aerial data of a large area.  This allows responders to map the entire search zone and pinpoint possible places where the missing person might be trapped.
  • Detect and identify:  Drones can carry different sensors that can be used for identifying ground objects. In the next section, we will discuss in detail how these sensors are used.
  • Communication: A drone, carrying a loudspeaker, can repeatedly broadcast a message making the missing person aware that people are looking for him/her.

How drones are used during search and rescue missions

The real power that drones provide to rescue operators is the easy access to aerial data of a large area, which gives the rescue team the ability to expedite the process of finding a missing person, where every second count.

What kind of data is useful in a search and rescue mission?

Drones can carry different types of payloads that can be used in different situations. Two of the popular payloads are the 4K wide-angle camera and the thermal camera that are extensively used during search and rescue missions.

HD video from a drone is not that useful in a search and rescue mission, since the resolution is lost when looking at a still image. On the other hand, a high resolution still image can provide valuable information to the people on the ground looking for the missing person. This is why cameras that can capture high resolution still images are preferred.

Thermal cameras are also used in search and rescue missions, especially during night time missions.

What is a thermal/IR camera?

A thermal/IR camera is a sensor that can detect a small section of electromagnetic waves called infrared. These are not part of the visible light that we can see.

Anything that has mass emits infrared radiation that can be captured using a thermal camera. The camera shows the image in different shades of color or grayscale to denote varying degrees of temperatures.


How thermal cameras are used in search and rescue missions?

In the year 2019, an 88-year-old man from Brownsville, Texas went missing on a Monday evening after leaving his home. When the family of the man informed the police about the disappearance, a local search and rescue team was formed with help from the police and fire department.

It was not until late at night that a local drone operator was involved. Around 11 PM, drone operator Desi Tristan spotted the old man near a field in tall grass.  The drone operator was scanning the area with a drone equipped with a thermal camera. The old man, identified as Luis Reyna Zuniga, suffered from an unspecified medical condition that led to this incident.

Here are some popular drones used for search and rescue missions

A thermal camera is a pivotal part of any aerial search and rescue mission. Drones that can carry a thermal sensor and can fly for a considerable amount of time are preferred for such operations. Here are some popular models from DJI that are extensively used for public safety operations.

How FlytNow enhances the capabilities of drones (UAVs) in search and rescue missions

FlytNow is a cloud-based drone fleet management system that provides a unified dashboard to control multiple drones along with the live streaming of video and telemetry data.

What problem does FlytNow solve?

The traditional use of manually operated drones during a search and rescue mission hinders the sharing of drone data among different agencies (fire, police, and EMS) and thus making collaboration difficult. The problem compounds when using multiple drones flown by multiple pilots. This is where FlytNow comes as a cloud solution that connects ground pilots with a web-based dashboard that aggregates all that data, making sharing of data easy, and provides a command center to manage all the drones. The below illustration shows how the solution works.

How drones are connected to FlytNow?

FlytNow supports the popular DJI drones as well as custom drones based on PX4 and Ardupilot.

Connecting a DJI drone is easy. First, download the FlytNow mobile app and connect the mobile with the RC. The mobile connects the drone with the cloud application, allowing it to stream live data and video.

Connecting a custom drone requires a Single Board Computer (SBC) with the FlytOS operating system connected to the flight controller of the drone. The SBC establishes a connection between the drone and FlytNow via the internet over a WiFi or 4G/LTE/5G module.
