Design
and development of a system for the remote control of spectrum analyzers from multiple control workstations for the Hellenic Navy. With the system,
users are able to control multiple remote spectrum analyzers from multiple
control stations, transfer, display and process spectrum data to the
participating in the network control or passive workstations. The control
of each spectrum analyzer can be transferred between the network
workstations.
The system was realized by using sophisticated compression
algorithms over a private leased line network. Implementation: The
system is implemented in order to
synchronize the broadcasting parameters of pairs of radio transmitters and
receivers and operates under the title "Broadcasting Monitoring System R
2.10".

Design
and development of a system for the remote control of transmitters,
receivers and antennas from multiple control stations for the Hellenic
Navy. With the system, users are able to control remotely transmitters,
receivers and antennas from multiple control stations, transfer and store
the functional status of each remote device to a central location. The
control of each pair of a receiver / transmitter and the corresponding
antenna can be transferred between the network workstations.
The system
was realized by using encryption - decryption algorithms over dial-up PSTN. Implementation: The system is implemented in order to control
remotely VLF/LF radio transmitters, receivers and antennas and operates
under the title "RCULF R 2.40".

Design
and development of a system for the automated measurement
or the operational conditions of electrical generators driven by diesel
engines. The system was developed
for the Hellenic Navy. The system is developed in order to monitor and control a number of
operational parameters, either in digital mode (on/off) such as diesel on,
generator synchronization on, power auto switch on, power auto switch off
on error, diesel in manual mode, reverse power on, generator high voltage
output on, synchronization error on, diesel low oil level on, diesel low
oil pressure on, diesel high oil temperature on, diesel high cooling water
temperature, diesel low cooling water level, air compressor low cooling
water pressure, or in analogue mode, such as electric power, voltage,
frequency, generator wiring temperature and diesel exhaust system
temperature. The system displays the operation parameters at a workstation
color monitor and in case of operational error visual and audio alarms are
generated. The alarms are displayed at the monitor and printed-out
automatically. The system maintains a continue log file of the operational
conditions and the alarms that is also printed-out. Finally the system, in
case of alarms, executes automatically corrective control actions defined
in a set of possible conditions – corrective actions scenarios.
The
system is used in several locations where one or multiple generator are
installed. The
system operates under the title "K14 R 1.50".

Design
and development of a number of software applications that emulate Radio Transmitters and
Receivers hardware RCU in order to help the development of remote
monitoring and control projects. The same software applications were used
during the test phase of each project in laboratory environment.
The
emulators that were developed was Rockwell’s Radio Transmitter Exciter
RCUs of model HF 8010, HF 8014, HF 8151 and
RACAL Radio Receivers RCUs of
model CCI R3050, R3040.
