Key highlights
The Remos SmallSat Ground Station is a turnkey VHF/UHF/S-band ground station for low-rate TT&C and LEOP support. The antenna suite includes cross-polarized UHF Yagi arrays (17 dBi, 399–438 MHz), cross-polarized VHF Yagi arrays (14 dBi, 137–146 MHz), and a 1.9 m mesh parabolic dish for S-band (29 dBi, 2025–2290 MHz). RF path automation is handled by the Remos Sequencer, providing deterministic Tx/Rx switching, HPA/LNA control, and safety interlocks. The Remos Expedite software modem coordinates pass scheduling, Doppler compensation, antenna control, and modem processing from a single operator environment. Indoor rack equipment connects over LAN/WAN; outdoor antennas mount on positioner and dish mounts. The system integrates natively with the Remos Umoja platform for multi-site orchestration and GSaaS network management. Suitable for GSaaS delivery, mission rehearsal, and nominal multi-pass operations.
