We had the opportunity last week to view Snowflake field tests at CIRPAS McMillan Airfield. The Arcturus launched a pair of Snowflake parafoils from 3500-ft, and upon touchdown, the Snowflake controller transmitted GPS coordinates that were relayed to the robot. The robot then autonomously moved to the transmitted coordinates using a script written in picoC. We witnessed 3 successful UAV launch and robot retrieval cycles. Future tests will include drop of a smaller version of the Surveyor robot by parafoil.
