Mavic Pro kit for search and rescue operations

I am assisting a local agency with developing a SAR UAV program. Among other things, we will develop use cases and their attendant requirements to drive platform selection but for the moment we’re using DJI Mavic Pros.

What follows is my working UAV SAR kit built around the Mavic Pro.

Each component of the kit will be discussed in more detail below. Clockwise from the upper left we have:

  1. Lightweight HDMI external monitor, USB or 12V DC powered
  2. Microsoft Surface Pro
  3. Molle water bottle carrier (repurposed as a Mavic carrier)
  4. Semi-hard shell Mavic case
  5. Dedicated phone, external battery, cables, and spare props
  6. Dual radio harness with type approved VHF radio, type approved air band radio, GPS
  7. Rapid parallel battery charger, 12V “cigarette lighter” charger

 

External data viewing and processing

The kit includes a Microsoft Surface Pro running Windows 10. It doesn’t really have enough power to run Pix4D (for example) but it is sufficient for some in-field image processing. It can also run Mission Planner for PixHawk enabled UAVs and can serve as a backup data storage device.

The item on the left is a very inexpensive, lightweight, USB powered HDMI screen. The Surface Pro drives it quite well. We need to determine is the Mavic controller can.

Molle Mavic carrier

This is a molle water bottle carrier with a large semi-padded main compartment, a zippered front pouch, and a zippered lower pouch. The Mavic Pro fits snugly in the main compartment with room for a spare battery below it in that compartment. A second spare battery fits in the lower zippered compartment. Cables, phone, and other small items fit in the front compartment. There is no room for the controller but we will attach another molle bag to the side of this carrier to hold the controller.

This would be the bare minimum kit and could be strapped to other gear or carried on its own.

Semi-hard shell Mavic case

There are lots of Mavic cases out there. We went with this one because it has room for three spare batteries, the foam is laser cut rather than pick and pull, and the case is semi-rigid.

We also added prop clips (white item over Mavic) to hold the props in place when using the molle carrier, a controller stick guard (lower right, black) to keep the sticks from moving or being damaged when not in use, and a phone mount that moves the phone above the controller and allows for phones in hard cases to be used.

Dedicated phone, external battery, cables, and spare props

All SAR flight operations must use a dedicated mobile device rather than a personally owned device. This limits exposure to malware, keeps potential evidence on a device owned by the organization, and provides for consistency across kits. This happens to be a Galaxy 8, chosen for maximum screen brightness.

Also included here are an external battery for recharging the phone, a charger for the phone, spare props, and spare cables.

Dual radio harness, radios, GPS

IMG_2637 (1)

The UAV operator needs to be able to communicate with others involved in the response and also with other manned and unmanned aerial assets. The kit includes a type approved VHF radio for response communications and a type approved air band radio for air operations. (The pilot program lead operator has a ham license (not required for this equipment) and manned aircraft ratings.)

Also included is a GPS unit. The team normally uses Garmin Alpha 100’s which automatically transmit on MURS frequencies to enable base to track assets in the field. To limit potential sources of interference, this GPS unit is passive and does not broadcast.

Rapid parallel battery charger, 12V “cigarette lighter” charger

IMG_2638 (1)

The standard Mavic battery charger is serial – it charges one battery, then the next, then the next. Charging three batteries can take upward of four hours. This charger will charge three batteries and the remote controller in parallel, dramatically improving available flight time.

The stock 12V cigarette charger is included to go out with the molle carrier kit.


 

And that is the working draft of our basic Mavic Pro SAR kit.

Questions, comments, and feedback are most appreciated.

Guidance to UAV Operators Responding to Florida

September 9, 2017 Leave a comment

[I am the Public Information Officer for National Council on Public Safety UAS. This post is written in that role. We will stand up an official location for future announcements.]

The Director, Emergency Management and Homeland Security Program, FSU, working in conjunction with local, state, and Federal agencies, requests that all volunteer UAS operators respect the following:

Volunteer/humanitarian aid/emergency response operators:

  1. Do not self-deploy during response/life-safety, it’s dangerous.
  2. Register on volunteerflorida.org.
  3. When the State gets to recovery, we will need help. Registered volunteers should report to a Volunteer Reception Center for vetting and assignment.
  4. Be prepared to be self sufficient. Do not assume that food, shelter, water, transportation, power, medical support, and fuel will be available to support your activities

Commercial operators:

  • All commercial operators working for utilities, insurance companies, etc should comply with their Part 107 restrictions.
  • Please coordinate operations through local and state EOCs if flying during response phase.

Official agencies:

  • Official agencies should contact the FAA Systems Operations Support Center (SOSC) at 202-267-8276 and request an Emergency COA or SGI. This authorization will permit operations inside any posted TFRs or within controlled airspace.

 

All operators in Florida should utilize Airmap (including registering of flights) for maximum visibility. Emergency Management is using Airmap to help deconflict air operations.

Other guidance:

  • Low flying aircraft will be an issue. 
  • Monitor FAA and other resources for new or changing TFRs.
  • Follow the eCOA process when working with a sponsoring agency or private sector partner. 
  • Be patient with the SOSC as they will get bombarded with requests
