Capella Space SAR constellation is an operational commercial X-band SAR mission launched 2018-12-03 and operated by Capella Space.^[1]^[2] CEOS lists a sun-synchronous orbit at approximately 575 km altitude with a 0.25-day repeat cycle.^[1] Each satellite carries an X-band SAR operating at 9.4-9.9 GHz with up to 600 MHz bandwidth, supporting spotlight, sliding spotlight, and stripmap collection modes in single-polarisation HH or VV.^[2] Capella offers commercial SAR data for maritime domain awareness, infrastructure monitoring, and disaster response, and supports repeat-track InSAR workflows for long-term deformation monitoring.^[3]^[4]
