Secondly, it gives you a very prominent GPS time. This is the critical thing – it displays the time to the second. So the app gives you your AGL, GPS time, airspeed and then has an event logging function. Now you can start logging locations whilst it records that GPS location, your height above the ground and your speed every second. This allows you to flag an exact position for more detailed ground-based inspection.
In addition the Flying for WildLife team have got cameras that are taking photographs every two seconds on both sides of the aircraft. The idea being these photographs are used to validate any sightings seen utilizing the displayed GPS time as the common factor.
