A small change in the frequency
of the transmitted or received signal in the wrong direction
could spell disaster for communications traffic and lead to lost
reputations in a highly competitive industry.
The Orbit Research EAFC system
- now operating in all four Inmarsat ocean regions- provides
the key to accurate frequency control.
At least 10 times more accurate
than the required Aeronautical specification, the Orbit EAFC
unit uses a unique system for ensuring perfect control of the
traffic uplink and downlink carriers which will meet the new
challenges of mini-m and satellite paging.
Engineers at Orbit Research have
worked closely with LES operators and Inmarsat to develop what
we believe to be the best solution possible for frequency control
now available.
The Orbit EAFC measures and calculates
satellite Doppler and provides an ultra low phase noise reference
to the traffic up and down converters. Our system is very flexible
in design and can be configured to operate with any third party
frequency converter. |
