RPM Model PG-1000 Pedestals

PG-1000 Elevation over Azimuth Pedestals on the assembly floor

PG-1000 Elevation over Azimuth Pedestals on the assembly floor

Used for test and instrumentation, satellite communications, unmanned vehicles, etc., these El/Az Antenna & Sensor Positioning sub-system pedestals are of a post type design, allowing customer-supplied devices to be mounted in the front and on the sides of the top section. Each pedestal can mount up to an 8-foot antenna, depending on the operational scenario; such as pointing and tracking requirements and wind loads.

The PG-1000 Pedestal can be fixed to the ground, mobile on a trailer, shipboard, or attached to a non-penetrating roof mount. The controller is mounted to the pedestal base, enabling a compact design, using Ethernet or EIA-422 standards for control.

  • Post design
  • Single-gear or dual-gear/zero-backlash drives.
  • Exacting positioning: 15-bit resolution or better, depending on requirements
  • High velocity and acceleration (>30°/s²)
  • Environmentally-sealed for wide temperature range outdoor use
  • Interlocked stow-pins for setup and transportation
  • Electrical and mechanical limit stops for all axes
  • Power: 120 VAC, 50/60 Hz (Alternates available)
  • Provision for limited amount of internal cables, slip-ring, or rotary joints
  • Units shown are tall to reduce operational interferance with built-up snow locations

PT-0701 Elevation over Azimuth Pedestal

Used for test and instrumentation, this video-tracking El/Az Sensor Positioning sub-system pedestal is of an open yoke design, allowing customer-supplied devices to be mounted both inside and outside the center section. The pedestal has a unique alternate mirror configuration that allows for mounting of a mirror in the center section that rotates at one half the main payload elevation angle.

The pedestal is mounted to a wheeled platform with leveling feet for lab or field transport. The controller is mounted to the pedestal base, enabling a compact design.

  • Open yoke design
  • Large, direct-drive, zero-backlash motors
  • Exacting positioning: 21-bit resolution, 17-bit accuracy
  • Alternate mirror configuration moves at 1/2 speed.
  • High speed and acceleration (>60°/s²)
  • Environmentally sealed for wide-temperature-range outdoor use
  • Interlocked stow-pins for setup and transportation
  • Electrical and mechanical limit stops for all axes
  • Power: 120 VAC, 50/60 Hz (Alternates available)
  • Provision for limited amount of customer internal cables
