Multiple Participant Airborne S-Band TDMA data link with up to 400 slots per second.
Transmission rate is up to
625KB/sec. The data link is built for 20 airplanes. It includes 200 time slots per second.
Each
participant broadcasts 300 bytes of useful information 10
times per second (Hz).
Using standard airborne omni directional antenna, the DataLink has
a useful range of 60-70NM range. Ground station with high gain
antennas achieves ranges exceeding 120NM.
The system includes a miniature Rugged PC computer, a
data link modem, and a 50Watt FM transceiver.
Computer PCM (NRZ-L) data pulses are transmitted in selected time-slots. Demodulated bit streams from the FM receiver are processed by BES Systems' digital
Bit-Synchronizer and handed over to the application program in the host
computer.
The system interfaces with aircraft Mission
Computer via MIL-STD-1553 or Ethernet bus.
A sound blaster board is
capable to output audio messages to plane intercommunication system.
