 State
of the Art |

| |
|
|
The 2010 TACAN is present generation equipment which has been developed
using the latest technology. It fully complies with Mil-Std
291B and the relevant sections of ICAO Annex 10. The 2010 is suitable
for independent siting and for co-location with all known VOR and DVOR
systems. The advanced features of the 2010 are brought about by the extensive
use of programmable logic devices (PLD’s).

Reliability |
|
| |
|
Fernau has paid particular attention during the development of the
2010 to equipment reliability and maintenance aspects. Use of the latest
technology and more reliable components has set new standards in reliability
and maintainability. A typical 1kW power amplifier unit has a calculated
MTBF in excess of 100,000 hours. In addition to this, each power amplifier
has its own “fail soft” characteristics and self correcting
ability, to adjust the system back to the designated power level. The
modern design will see the 2010 TACAN operational well into the 21st Century
providing MTBO of 12,000 hours and more.

Flexibility
|
|
| |
|
|
The 2010 is available in a variety of configurations including single
and dual, with output power up to a full 5kW, capable of an operational
range of more than 300NM. Other alternatives are available including road
and C130 transportable systems. The dual 2010 TACAN is able to operate in
TACAN, silent, demand and DME only modes.

|
Remote
Control |
|
| |
|
The 2010 has a powerful remote control facility that includes control
of the output power, operating channel, operating mode and transponder ON/OFF
etc. This allows a new dimension in tactical control of the entire 2010
TACAN network, which can now be performed from a central location, without
the need for costly and time consuming site visits. System tuning and alignment
can also be carried out from a remote terminal.

|
|
Remote
Maintenance and Monitoring (RMM)
|
|
| |
|
|
The 2010 TACAN Beacon has an integrated, powerful, monitoring and maintenance
system with results displayed on a local and/or remote PC. The RMM system
has a number of display screens showing operating parameters, overall system
status, LRU status, alarm limits, diagnostics and test information, amplifier
status, transmitter control status and many more. This allows the maintenance
engineer to judge the optimum time to effect repair before failure or shutdown
occurs.

|
Active
Transmitter Control
|
|
| |
|
A feedback control loop is used to provide control of the Pulse shape
and Spectrum, and to keep them within permissible limits, over all operating
conditions and providing self correction wherever possible.

Maintainability
|
|
| |
|
|
All LRU’s are plug-in and accessed from the front of the TACAN
cabinet. By using the RMM system for fault indication, a typical faulty
module would take less than 15 minutes to identify and replace. All LRU’s
have unique pin positions to prevent a module being inserted into the wrong
position. The BITE system continually monitors the TACAN system and gives
an alarm indication in the event of a module failure, system transfer, or
shutdown.

|
Cost
Effectiveness |
|
| |
|
The 2010 TACAN systems allows for reduced life-cycle costs by the use
of the extensive RMM system and site visits are thus reduced to an absolute
minimum. Where a site visit is required due to a module failure, the RMM
system provides the engineer with the fault location which means that the
correct spares are taken on site. The 2010 allows for the “hot replacement”
of modules which means that the equipment remains operational even while
a module is being replaced.

|
|
Antenna
|
|
| |
|
|
The 2010 TACAN is capable of operating with any suitable TACAN antenna.
For improved reliability, we recommend Fernau’s own electronically
scanned antenna which fully complies with MIL-STD-291B, ICAO
Annex 10 and provides unparalleled reliability - reliability proven in
all environments. MTBF of >70,000 Hours is standard and BITE allows
fault isolation to LRU level. With low power consumption, the Fernau antenna
even saves money in operation.
