Adhika, Andrei, Arion, and Brian arrived at ACRC around 2:00pm to test a quaternion navigation filter on Thor during a manual flight and to gather closed-loop pitch doublet data to characterize the closed-loop response of the aircraft in the longitudinal axis. Additionally, two waypoint tracking algorithms were tested on Thor, an expanding square and a sector search. Finally, static and low speed taxi ground test data was gathered on GPS FASER for Adhika's research and to quantify the quality of GPS reception for the three receivers in an open sky environment. Software used for this flight was trunk/Software/FlightCode rev 929. Thor flight80 was conducted using the revised waypoint guidance algorithm (path_track_newsector.c). This consists of a sector search algorithm, which should have produced a clover-leaf flight pattern; however, the algorithm did not work as expected and needs further investigation and data review.
