TRISKEL (OBC+TTC+OBSW)

Price on request

TRISKEL is a three-in-one solution for the command and data handling chain of your satellite. It integrates the On-board Computer (OBC), Telemetry, Tracking, and Command (TTC) and On-board Software (OBSW) in one module allowing communication with ground stations in the UHF band while saving space in the satellite’s platform.

Lead time: 12 weeks
