iIPSC-ANTRAD: Systems for Dynamic Antenna Stabilization and Pointing

Gyro / INS based Antenna Pointing for Naval and Surface Vessels

The iIPSC-ANTRAD familiy covers gyro controlled stabilizers for communication antennas and radar antennas. They are designed for fast positioning and pointing tasks, high angular accuracy and operation on moving 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) or three axes (e.g. to maintain a stable polarization direction) stabilization.

Features of iIPSC-ANTRAD-101 (single axis azimuth):

  • angular speed up to 300 °/s, acceleration > 300 °/s² 
  • antenna payload up to 15 kg (or customized) 
  • angular resolution < 1 arcsec, linearity < 0.003 %
  • gyro stabilization better 0.1 ° or 0.02 ° or TBD (depends on used gyro / IMS); options: iNAT-M200, iNAT-FSSG, iNAT-FSLG; additional geo-referencing as an option integrated
  • stabilization bandwidth > 100 Hz possible using internal gyro feedback
  • Interfaces: Ethernet (TCP/IP / UDP), CAN, UART RS232/422
  • Power supply: 24 V, 360 W (max) [depends on desired dynamics, can be limited by software parameters]
  • RF sliprings (standard): DC to 2.2 GHz, 6 lines
  • NF/DC sliprings: 20 lines, each 2 A
  • Protection: IP66 at radome side
  • integrated auto protection of drive system
  • open frame architecture, can be specifically adapted to customer's needs (size, torque, interfaces, transmission performance of radom at certain frequencies)

Features of iIPSC-ANTRAD-102 (single axis azimuth):

  • angular speed up to 50 °/s, acceleration > 50 °/s² 
  • antenna payload up to 15 kg (or customized) 
  • very low height profile
  • angular resolution < 1 arcsec, linearity < 0.003 %
  • gyro stabilization better 0.1 ° or 0.02 ° or TBD (depends on used gyro / IMS); options: iNAT-M200, iNAT-FSSG, iNAT-FSLG; additional geo-referencing as an option integrated
  • stabilization bandwidth > 100 Hz possible using internal gyro feedback
  • Interfaces: Ethernet (TCP/IP / UDP), CAN, UART RS232/422
  • Power supply: 24 V, 360 W (max) [depends on desired dynamics, can be limited by software parameters]
  • DC slipring 20 lines, each 2 A and 1 line FORJ (fiber optic rotary joint) for Ethernet
  • Protection: IP54 at radome side
  • integrated auto protection of drive system
  • open frame architecture, can be specifically adapted to customer's needs (size, torque, interfaces, transmission performance of radom at certain frequencies)

Features of iIPSC-ANTRAD-201 (dual axes azimuth/elevation):

  • similar to iIPSC-ANTRAD-101, but dual-axes (azimuth/elevation) design, carrying a 60 cm dish for satellite communication 

Features of iIPSC-ANTRAD-301 (three axes azimuth/elevation/polarization):

  • similar to iIPSC-ANTRAD-201, but three-axes (azimuth/elevation) design, carrying a 50 cm dish for satellite communication

Beside of iIPSC system family, with its open system architecture iMAR Navigation also provides so-called upgrade sets (UGS), which are used to upgrade existing platforms of various manufacturers with enhanced inertial stabilization, target tracking and control capability for line of site (LOS) stabilization of camera, antenna or weapon payloads on mobile platforms on ground, sea and air.
