1 Development and Implementetion Researches of UAVs in Lithuania Domantas Bručas Space Science and Technology Institute

2 Introduction Development of nano-satellites and its systems; Working on satellite orientation led to additional testing of autopilot systems; Interest of partners in low cost UAVs, led to UAV development.

3 Initial testing Classical configuration; Mass up to 3,5 kg; Wing span 1,8 m; Cruise speed 13 m/s; Endurance up to 45 min; Advantages stability, low stall speed; Disadvantages high drag, large dimensions.

4 Geo-Mapping applications Flying wing; Mass up to 1,5 kg; Wing span 1,1 m; Cruise speed 17 m/s; Endurance approx. 45 min; Advantages low drag/high speed; Disadvantages instability, high stall speed.

5 Control system ArduPilot autopilot; 3DR 433 MHz 100 mw telemetry communication; MissionPlanner software; The total price of the system not exeeding 400 euros (in Europe).

6 Composing of the equipment Canon S100 camera with remote control; Special camera control board; RC receiver; Autopilot; Telemetry module.

7 Launching Fully automated; From hand; Catapult in development.

8 Landing Automated belly landing; Automated parachute landing; Camera protection door.

9 Automated parachute deployment After several crashes due components failure and automated parachute deployment was developed.

10 Aircraft data Payload up to 400 g; Mass up to 1,5 kg; Wing span 1,1 m; Cruise speed 17 m/s (61 km/h); Endurance approx. 45 min; Total flight distance approx. 50 km; Allowable wind up to 12 m/s (normal operation), up to 15 m/s (reduced images quality); Practically no limitations due to rain, snow, fog, darkness etc. (limitations of camera sensors); Operational distance up to 10 km (omnidirectional antenna), up to 15 km (Yagi antenna); Camera (one of) implemented Canon S MP; Image download mini USB.

27 Conclusions Automated small UAVs have great future in civil land surveying applications; Small UAVs due to its low price can be implemented in different applications in great numbers; The UAVs should have as little of manual input needed as possible to decrease the human related errors; Ground surveying UAVs implemented in winter environment must have the camera optics protection to decrease the moisture influence; Parachute landing system is preferable in northern Europe; Parachute landing system increase the safety of UAV considerably; The price of the UAV can be decreased by implementing cheap mass production components.
