Service friendly system
The system configuration is saved in several modules, there is no loss of data at repair.
There is a switch in the ADU to turn off the power to the antenna. All modules have an LED
status indicator. Each module is encapsulated in a metal box with self-contained mounting
bolts. If necessary, belts and modules can be exchanged through the service hatch on site
for the 100 cm antenna.
You can do remote diagnostics and service. The built-in test equipment of the antenna
checks constantly the antenna modules for proper functioning, it monitors and logs
information for all modules. The ADU performs a POST (Power On Self Test) and you can
request a self test (PAST, Person Activated Self Test). Continuous Monitoring (CM) is always
enabled. Error codes are read out in the web interface and in the display of the BDU. ADU
software is updated automatically when making a software update through the BDU.
1.1.1 Above Deck Unit (ADU)
The SAILOR XTR Ka ADU is a 103cm or 60 cm VSAT stabilized tracking antenna, consisting
of a suspended antenna with a standard global RF configuration. It is stabilized by heavy
duty vibration dampers in 3-axis and can be used in environments with elevations of -18° to
+118° for 100 cm and -28° to +120° for 60 cm. The 100 cm antenna weighs 105 kg, the
60 cm antenna weighs 37 kg. The antenna is powered by the BDU and protected by a
radome. All communication between the ADU and the BDU passes through a single
standard 50 Ohm cable (with N connector) through the rotary joint. No cable work is
required inside the radome. The 100 cm antenna has 4 LAN connectors and a DC power
outlet in the ADU to connect third-party equipment. The antenna comes with lifting
brackets pre-mounted.
