After arriving at the Oliktok Point Long Range Radar Station (LRRS) around midday yesterday, we spent the afternoonÌýat the atmospheric observation facility (called the AMF)Ìýpreparing the small fleet of DataHawk aircraft for flight, and the evening getting oriented at the LRRS.

In the morning, after a quick breakfast, we piled into the pick-up and returned to the AMFÌýto finish preparing the aircraft. Although the physical assembly was complete, a software issueÌýin the autopilotÌýcausing loss of RC link forced us to break forÌýlunch withoutÌýcompleting radio range checks. Work on the autopilot took place after lunch. Running several simulations of proposed flight paths testedÌýthe paths,Ìýstored them for future use, and providedÌýtraining for the crew. Despite the continuing rain and fog, the forecast showed potential for flight appropriate conditions after dinner. Upon reaching the AMF in the evening, half of the crew took the plane in the truck and droveÌýeast toward the oil rig on the point while the other half monitored the radio link status. At 1.4km, the radio controlÌýlink remained strong, but the telemetry link had dropped to -85dB. Given that the aircraft was on the ground and in the truck, weÌýanticipate range to be significantlyÌýgreater than 1.4km.ÌýUnfortunately, the weather had notÌýimproved as forecast, andÌýflying was pushed off to tomorrow.

After range checking, we took time to calibrate the IR sensors on the top and bottom of the aircraft. Using a FLIR infrared camera to provide a temperature reading, the aircraft was positionedÌýover several different surfaces to obtain temperature data. This data was usedÌýto generate a curve that willÌýbe used to interpolate temperature. In flight, the IR sensors will be used to determine the temperature difference between land and sea.Ìý

In all, things are going well here, despite the delays in getting aircraft inÌýthe air. Given the forecast, flying tomorrow is very likely. We are looking forward to at least testing the systemsÌýbefore moving on to full profiles.
