Modem

Modems permit the transmission and receipt of modulations in the fields of observation and scientific missions. They come in different multi-mission products according to use cases and signal rates implemented.

UHDRM

The UHDRM (Ultra High Data Rate Modem) is a new demodulator designed to receive ultra high speed signals. This equipment, integrated with ground stations and test benches, allows for receipt of these modulations in the fields of observation and scientific missions.

HDRM

The HDRM is a demodulator designed to receive very high rate signals. This equipment, integrated into ground stations and test benches, allows for the receipt of modulations in the domains of observation and scientific missions.
