MAV Programme at CASDE

Goal :

• Aircraft maximum dimension 60 cm

• Waypoint based navigation

• Videography role

• Endurance of 20 mins

• Operation range < 10 km

• Easy handling

MAV Programme at CASDE

Approach :

• Prove autonomous mission on aircraft < 2 m (Kadet)

• Design aircraft < 0.6 m (max size)

• Optimise avionics for a 0.6 m size aircraft

• Test new aircraft and system

• Perform autonomous mission

Past studies

Instrumented. 2.5 kg, 1.6 m.

2000

Solar. 0.13 kg, 0.25 m.

2002

Videography. 0.9 kg, 0.6 m.

2001
