During the campaign four flights were made. Three using the standard platform with the Dornier airplane and one using the UAV/DRONESPEX.
April 22, 2006: Flight 1 - Longyearbyen
The first flight was performed under rather bad conditions, with heavy winds. After discussing with the pilots it was decided that we would fly the red route from West towards East at an altitude of 1000 meters. Unfortunately there was a bug in the program used to generate the coordinates that was to be given to the pilots as flight plan. This resulted in a mixup of coordinates and the blue route was flown from West to East. The image below shows the possible routes to be flown, the planned one being the red going from left to right in the image. The green line shows the actual route flown.

April 30, 2006: Flight 2 - Longyearbyen
The plan was to fly the second flight along the red West-East route over Longyerbyen shown in the map above. The was the same as planned for flight 1, but the with the right coordinates this time. The wind conditions were significantly better, but a low cloud cover prevented flying at 1000 meters. Instead the plane flew at approximately 530 meters and made three turns in Adventdalen.

May 3, 2006: Flight 3A - Longyearbyen
This day the flying condition was almost perfect, with little wind and a high cloud cover. The only backside was haze due to pollution transported from Eastern Europe and Russia to Svalbard. The pilots flew over Longyearbyen twice, once from South towards North, and once in the other direction. This was done at 1500 meters height, along the green lines in the map below. The red lines shows the calculated center field of view point of the spectrometer system, calculated from the measured pitch, roll, yaw and altitude of the airplane.

May 3, 2006: Flight 3B - Svea
After flying over Longyearbyen twice the plane headed towards Svea, the mining town 60 kilometers from Longyearbyen. The town was overflown twice, before returning to Longyearbyen airport. Click on the link to view Data and analysis from flight 3B.

May 5, 2006: UAV flight - Longyearbyen
This was the first proper test of the UAV/DRONESPEX system at Svalbard and the first time the DRONESPEX was flown onboard an unmanned aircraft. Click on the link to view Data and analysis from the UAV flight.
