About
The OGS-2.5 model supports the physical layer of SDA and CCSDS standards. The system is based on a proven telescope and direct-drive positioning system, seamlessly integrated with a custom fine pointing, tracking and data processing system. It offers two options for aperture size: 355 mm (14 “) or 508 mm (20 “). The operational wavelength is 1536 nm & 1553 nm, supporting OOK modulations. It provides a downlink data rate of 1.25/2.5/12.5Gbps and an uplink data rate of 1.25/2.5Gbps. The tracking accuracy is less than 50 μrad RMS, and it features an uplink beacon of 35 W, C-band (1546 nm & 1553) or 10 W, L-band (1590 nm).
