Event Day

A Cessna 206 “jump plane” and pilot were arranged for the entire day of August 2, 2011, at a drop zone near Innisfail, Alberta (52°04'40” N, 114°01'30” W). Setup began around 8:00 AM, with base station setup and a final check of the aircraft and skydiving equipment. Andrew and his wingsuit crew rehearsed their techniques for executing a coordinated exit from the plane, and discussed specific flight plans for the day.

The two OEM615 receivers were strapped (and taped) to Andrew's legs near his feet, with the battery pack similarly strapped to one leg. A small pocket of space within the wingsuit, just above Andrew's feet, provided barely enough space for all of this equipment. The data collection PC was carried in a small backpack, worn in front on Andrew's chest.

With one dual frequency GPS+GLONASS antenna mounted on each foot, Andrew's roll and yaw (heading) could be measured independently, (from the ALIGN HEADING log's pitch and heading outputs respectively).

In total, we conducted seven test jumps on the event day, with an average interval of about 90 minutes between jumps during which we re-packed the parachute, verified the data integrity, and conducted a rudimentary data analysis to decide if any changes were required to optimize jump performance.
