CPI SAT Orbital Systems Operations Antenna Positioners and Satellite Tracking Antenna Systems

- CPI SAT Orbital Systems operations' designs use servomotors and four-quadrant drives that minimize power consumption while providing full torque at near zero velocity
- Elevation over Azimuth fully counterbalanced systems draw little power while tracking unless subject to significant wind load
- Integrated mechanical system components, with IP65-rated brushless motors and internal brakes, matching motor drives tied to generously overrated heavy-duty gears
- Gears and drives automatically heat as needed for full performance to -40°C
- Gears are enclosed in a cast housing to further protect gear lubricants from dust and moisture for maximum longevity
- Tracking uses built-in precision GPS timing and location reference
- Positioners are controlled over Ethernet or Fiber to simplify interfacing to control computer systems. Using the simple control interface TLE ephemeris is stored for each satellite and the antenna tracks on command by simply naming the satellite
- No indoor rack space needed, as the controller is located in electrical cabinet at base of positioner
- High speed azimuth axis allows reliable tracking of satellites with no keyhole effect
- All structural metal is made from aluminum with stainless steel fasteners to eliminate rust
- Exposed surfaces are powder coated or hard anodized to maintain an excellent finish appearance for many years to come
CPI SAT Malibu Operations Telemetry Antenna Pedestals
[rimage=268][/limage]CPI SAT's Malibu operations provides telemetry antenna for ground-based, transportable, mobile or shipboard (gyro stabilized) applications. High output torque with low backlash is accomplished with the use of two-stage reduction gearboxes and brushless DC motors. The rugged gearboxes use built-in angular ball bearing construction, which improves the ability to support external loads, increases moment rigidity and increases maximum allowable moment, resulting in increased reliability and a reduction in maintenance. The use of roller bearings throughout the gearbox yields low backlash (less than 1 arcmin). For added reliability, pedestals are designed with servo amplifiers that have protection for over-current, voltage and temperature. O-ring seals on all panels allow for positive air pressurization of the pedestal. Advanced engineering, superior materials and in-house manufacturing make CPI SAT positioners intrinsically more robust and maintenance-free.Click on the links below for product sheets describing CPI SAT's antenna pedestal and positioner products.
