This mechanism was projected for mini-UAV. Low cost and unfailing work were a main principles of project. This unit enables 2- axis positioning by means of 2 fast servomechanisms. Carbon composite mechanics make the system light and enduring.

- Dimentions with camera and objective (width x height x length) -    50 x 52 x 70 mm
- Weight ---------------------------------------------------------- 78 g
- Positioning range ------------- ± 90° horizontal, -15 ÷ - 90° vertical
- Positioning exactness -------------------------------------- about 1°
- Camera -------------------- color , CCD 1/3”, resolution -520 lines,
                                             sensitivity – 0.3 lx , supply – 12 V/90 mA

This unit switch on and off the camera and TV sender (if supplied by the same valtage). It can be controlled from autopilot or RC receiver (1 channel). The galvanic isolation among TV system and RC receiver is realized. Max. switched current: 1 A, max. switched voltage: 20 V, module dimentions: 31 x 24 x 8 mm.

Unit enables the control of 3 still camera functions : zoom , shutter and switch on /off. Every function needs separate RC receiver (or autopilot) channel. Module is connected to still camera electronics end therefore is strongly recommended to mount it close to camera enclosure. Module dimentions : 41 x 25 x 8 mm.

The unit forms voltage waveform among 2 of 3 fases of brushless motor. At module output are generated 5 V pulses, frequency of which is proportional to RPM. To measure the RPM the control input must be biased to 5V. If this input is biased to 0 V the module generates pulses , frequency of which is related to battery pack voltage. Measuring this frequency we can obtain the information obout this voltage (after calibration). The circuits supplied by 5 V voltage and electric motor battery pack voltage are optoelectronicaly isolated. Module dimentions : 24 x 22 x 9 mm.

Converter enables the autopilot programming (serial port level 5 V) by means of PC or laptop (serial port levels ± 12 V). Module dimentions : 32 x 16 x 11 mm.

This module is the adaptation of u-blox GPS receiver (type LEA-4H) projected for cooperation with FCS-1 autopilot. The antenna connector and voltage stabiliser is added to the receiver. The module is directly mounted to autopilot case (at the bottom). Technical data are available on website www.u-blox.com.
