| FIG. 3 shows the CENTRAL
GROUND-BASED PROCESSING STATION
(CGBS) used for
collecting and disseminating the
digital data from a plurality of
aircraft and aviation sources.
The CGBS digitally processes such
sources and then ciphers the
digital data so that it can be
exclusively/uniquely/solely
utilized by the targeted aircraft
2. It also shows the
antenna 8 utilized for
transmitting and receiving radio
frequency (RF) ciphered two-way
digital data between the CGBS and
the targeted aircraft 2. Since there exists
a plurality of aircraft 2, each targeted
aircraft has a unique
identification (ID) that permits
the CGBS to process each
individual aircraft 2 as a unique
vehicle. The CGBS, by adding the
unique aircraft ID to its
transmitted data stream, can send
data to a specific/unique
aircraft, or send a general
message to a group of aircraft,
or a global message to all
aircraft. To assure the
integrity, security and
uniqueness of critical digital
data going to and from all
aircraft 2 the antenna control
and RF interface 23 perform the
cipher/decipher, anti-jam and
anti-spoof controller functions.
All of the communication both to
and from the aircraft 2 and other aircraft
are stored in the data storage 18 section of the CGBS
for archival retrieval should
that become necessary for post
flight analysis. The CGBS also
acts as the communication control
unit for the air traffic
control/management (ATC/M) module
19 data and the Air
Carrier and Aircraft
Manufacturers Communication
Module 20. In order for the
CGBS to process the large amount
of digital data, communication
and ciphering information a
processor 21 acts as an
intelligent controller. The CGBS
provides visibility to the many
transactions taking place at this
site via a display and control
system 22. The Remote Pilot
Simulator 7 communicates with
aircraft 2 though the ATC/M
Module 19. The Remote Pilot
Simulator 7 communication
to/from ATC/M Module 19, with aircraft 2 includes the
aircraft control parameters
(e.g.: aircraft ID, 3-D position,
3-D velocity, heading, velocity,
target state and target change
reports--waypoints, etc.) via the
secure ground digital data 5. The ATC/M.
weather, map, terrain and
security communication 4 from the
ATC/M Module 19 is
transmitted/received over the
secure ground digital data link 5. The ATC/M 19 and aircraft data
from a plurality of CGBS' is also
distributed over the secure
ground digital data link 5. |
