CPI SAT O3B 1.8m Ka-Band Terminal Antenna Systems
1.8m, Specifically designed and engineered for O3B
O3B 1.8m Ka-Band Terminal Antenna Systems
The CPI SAT (formerly GD Satcom Technologies & Prodelin) auto acquire / auto tracking Ka-Band series antennas are designed for O3b installations. The 1.8m antenna has been designed to provide reliable, trouble free service in a variety of environments. Each terminal is comprised of a pair of tracking antennas under the control of a single dedicated antenna control unit (ACU).
Autotracking
The O3b service is provided and maintained by the antenna pair acquiring and tracking alternate satellites in the O3b constellation. The tracking function is done by having one antenna acquire and follow a rising O3b satellite in MEO orbit with a pointing accuracy of better than <0.1 degrees while the second antenna is parked in a home position awaiting the next rising satellite. Terminals have been designed to support a range of Ka-band SSPB’s ranging in output powers from 5 watts to 20 watts.
High Tech Design
The mechanical design has been optimized for longevity to offer many years of service and packaging to reduce shipping costs. Material selections for the reflector significantly reduce the risk for shipping damage when compared to metal reflector solutions. Factory pre-assembly of critical components eliminates the requirement for complex assembly procedures in the field.
