Nera F77
Continuing the Saturn tradition
Reception of L-band Broadcast signals
In addition to regular 1.5/1.6 GHz, used for the various Inmarsat
systems, the transponders in the satellite also broadcast leased
channel info.
The design of Nera F77 with L-band (1.5/1.6 GHz) signals
between ADE and BDE, easily enable insertion of an Inmarsat
Demodulator to pick up broadcast RF signals via the
BROADBAND (DGPS)
TNC connector.
Such signals are Differential GPS (GPS corrections), Maritime
Chart Corrections, Radio Broadcasting channels, etc.
The diagram below indicates a typical installation for reception
of broadcast signals.
