Kratos NGC Outdoor Unit (ODU)

FEATURES

• The Kratos ODU is housed in a NEMA 4X aluminum enclosure and is designed to be mounted directly onto the antenna structure, minimizing the cable length to motors, limit switches and position encoders.
• Variable Speed motor control for two- and three- axis motor systems complying with the standard Kratos interface, using VFDs for driving the Azimuth and Elevation axes.
• Support for stepper motor type Polarization rotators (optional) utilizing Kratos proprietary NGC Bus, eliminating the need for the internal transformer and polarization control electronics.
• Support for Sub Reflector Tracking utilizing Kratos proprietary NGC Bus. The NGC ODU can simultaneously control 3 SRT Axes (X, Y, Z) as well as 3 main reflector axes (Az, El, Pol) motorization.
• Support for outdoor equipment redundancy control, removing the need for additional controllers and cables.
• Interfaces to the NGC-IDU (Indoor Unit) via fiber optic Inter- Facility Link, providing lightning protection to the NGC-IDU.
• Emergency Stop switches located on both the ODU and advanced handheld terminal. Optional remote ESTOP stations are available.
• Advanced handheld terminal provides local jog control and position designate capability. Handheld terminal reports detailed status of the ODU such as antenna pointing angles and limit switch status. The outdoor unit can be fully
configured from the handheld terminal.
• Embedded firmware is updated via USB ports located inside the ODU
• Onboard LEDs and seven segment displays provide low-level detailed status of the ODU circuits and peripherals.
• Configuration of the AC mains terminal block provides a means for powering the low voltage electronics separately from the VFDs using a nominal 220VAC ± 10% power supply, ideal for connecting a UPS to maintain communications between the NGC-IDU and NGC-ODU during power outages.
• Support for an optional Antenna Warning Light system, providing visible and audible warning signals indicating antenna pre-motion and in-motion status. The Antenna Warning Light system also provides an auxiliary LED element for customer defined use, such as Transmitter On, controlled by external SPST (Single Pol Single Throw) switch.
