GCS Hardware

The Modem is an essential part of any system based on a UAV Navigation autopilot.
 
The Modem connects via Ethernet to the PC and is available in two different versions:
  • GCS03:   with internal 900 MHz radio (up to 100 km range) - compatible with TELEM05.
  • GCS03-NR:   (no radio) for connection to an external datalink.
The Modem is supplied in a rugged, aluminium case.
 
The Modem provides the following features:
  • Bi-directional communications between Visionair (on the ground) and the onboard AP (in the air).
  • Connection point in the system for the Joystick to allow manual override by an External Pilot if necessary.
  • GPS (to locate the GCS; the position is shown in the top right corner of the GCS Config Tool window). GPS information is also integrated to steer a pan and tilt antenna if it is used.
  • Low-level message integrity verfication.
  • Built-in standby battery in case of external power failure (old version only).

MANUAL CONTROL

For fixed wing aircraft, manual control acts on elevator, aileron, rudder and throttle.

For helicopters, manual control acts on cyclic, collective pitch, rudder and throttle.

Joystick

Where manual control of a UAV is required, UAV Navigation (UAVN) offers the JY02, an R/C style joystick, for use with its system. The Joystick connects via a cable to the Modem.

A switch conveniently located on its upper panel enables the External Pilot (Safety Pilot) to take manual control of the RPAS/UAV; this is completely independent of the GCS computer, thus enhancing security in case of a PC failure.
 
The Joystick features professional quality gimbals and mechanical trims housed in a rugged aluminium case.
 
The unit also has 3 user-configurable switches for use in special applications (camera shutter release, smoke deployment for targets etc).
 

The Joystick requires no power supply as it is fed from the Modem.

Description

Twin gimbal joystick with three user-configurable two-position toggle switches on front face, plus one two-position toggle switch on upper left surface for selection of MANUAL mode

Weight

950g
