The iIPSC-ANTRAD familiy covers gyro controlled stabilizers for communication antennas, radar antennas, jammers etc.

The "D" devices (iIPSC-ANTRAD-xxxD) are designed for fast positioning and pointing tasks with high angular resolution and accuracy and for operation also on fast moving naval and surface vessels as well as in stationary environment, where also lowest angular hysteresis is required.

The "G" devices (iIPSC-ANTRAD-xxxG) are designed for medium fast and medium accurate positioning and pointing tasks with standard angular resolution and accuracy, for operation on naval and surface vessels as well as in stationary environment. 

Standard systems as well as customized designs are provided, from low weight to heavy weight payloads, with RF sliprings or Fiber Optic Rotary Joints (FORJ) or twisted cables.

The systems are avaialble with single axis (azimuth) stabilization (e.g. for phased-array antennas) or dual axes (azimuth / elevation resp. pan / tilt) or triple axes (e.g. to maintain also a stable polarization direction) stabilization and on request up to 5-axes to avoid any singularities.

All systems are available optionally with gyro stabilization, GNSS dual-antenna compassing or gyro compassng, or INS/GNSS geo-referencing. 

For heavy antenna payloads see our series iIPSC-MSG.
