Aerial Photography and The Tethering Process

Recently, Tether Tools played a pertinent role in the aerial mapping that SkyIMD, a company that designs and develops complete aerial imaging solutions for light planes and helicopters, was tasked with.

Along with SkyIMD, Corsair Aviation, based in Van Nuys, California, played a pivotal part as they provided the aircraft, knowledge and skills to fly the aerial mapping and survey mission. In addition, Phase One’s industrial aerial cameras (100MP and 150MP medium format cameras) were needed to complete this project.

Project: 19 Different Parcels In and Around Los Angeles, CA.

Our partner, Corsair Aviation (Van Nuys, CA) asked us to assist with some aerial mapping in the Los Angeles area. Due to the crowded and busy skies, we utilized a Phase One medium format digital camera that enabled us to capture 40% more data faster than typical DSLR’s.

Aerial Mapping & Survey missions require strict forward and side overlap of the images in order to create high resolution and high precision ortho-mosaic’s (many images stitched together and geo-rectified). The camera is triggered once per second. The file size of each image is 125MB ea. average.

Being able to control the camera via iX Capture (Phase One’s camera control software) while simultaneously download high resolution images every second, for over 5 hours straight, is mission critical.

Tether Tools’ TetherPro USB 3.0 to Female Active Extension cables are insanely reliable in our manned aviation environment.

The TetherPro Cables are also durable in our aviation environment. We run them down the strut and through the window frame into the cabin. Other cables created interference with our avionics/radios when routed/pinched similarly.  The TetherPro USB 3.0 to Female Active Extension cable shown in the photos has been in use for the last 3 years.  We carry a backup but haven’t needed it.

It’s the cable we supply to our customers. Some who are flying 4 Phase One Cameras simultaneously, using TetherTools’ active USB cables and TetherPro USB 3.0 to Female Active Extension for extended tethering.  They are capturing terabytes of data an hour and rely on TetherPro Cables. The JerkStopper Extension Lock is good for keeping out dust and moisture and the camera support prevents damage to our USB connections.
