These two models of Sony cameras have been used successfully at 12 to 14 m/s, Sony A6000 and Sony QX1 using this trigger cable trigger cable, both cameras using the Sony 16mm fixed focal lens for 2cm GSD and higher at 100m, triggering at 1 sec intervals. The Sony A6000 has a hot shoe, and the hot shoe adapter from Tuffwing or make your own, will capture the shutter activations, and long the activations to the Reach unit.
As Igor noted, this can all be calculated with math by hand/speadsheet or the fight management software used to setup a mapping mission. We use Mission Planner at the moment as we are using Ardupilot flight control software, on Navio2 and Pixhawk.
What is the GSD that is required for the deliverable?
What platform is being used(fixed wing?)
What flight controller is being used?
