Description
Summary:Helicopter position (latitude, longitude, altitude) and attitude (pitch, roll, true heading) were measured by an inertial measurement unit (IMU-57) as part of the combined global navigation satellite system (GNSS) and inertial navigation system (INS) Applanix AP60-Air (hdl:10013/sensor.a9fee346-91e7-4eed-9f2f-89f1368e53a0). The IMU received input signal from two AV39 GNSS antennae installed on the forward and aft cowlings on top of the main cabin of the helicopter. The IMU was mounted in the rear cargo compartment on a sensor plate together with the airborne laser scanner and the sensor plate was connected with dampeners to the helicopter airframe.The helicopter flights in this data set include surveys where the airborne laser scanner was operated along the MOSAiC drift from the north of the Laptev Sea, across the central Arctic Ocean, and towards the Fram Strait from September 2019 to October 2020. They are both small scale, ~5x5 km grid patterns mainly over the central observatory, and large scale, few ...
