C2SAT 1.2m Ku
The C2SAT 1.2m Ku is the standard
4-axes marine stabilised VSAT antenna compatible with Ku-band
satellites. Standard reflector diameter is 1.2 m.
Reliable Satellite Communication
High elevation problems are experienced with traditional
3-axes systems and occurs in a wide belt around the equator when a
vessel rolls back and forth and the satellite is close to zenith.
The problem is provoking loss of signal, restarts and downtime. The
4-axes solution designed by C2SAT allowes the RF equipment to move
freely and to maintain an optimal position towards the satellite
without big and sudden movements even during harsh conditions and
heavy seas. The 4-axes system does not experience dead angles and
does therefore not experience any high-elevation problems.
The high reability makes the C2SAT antennas suitable for use as
main connection point as the system can carry large volumes of
information without interruption. C2SAT gradient track system
identifi es and fi nds any selected satellite within 6 seconds. DVB
or DVB-S2 identification is optional.
Better Accuracy
The system achieves superbly high tracking accuracy (only
a loss of +-0,1 dB), comparable to a fi xed antenna. C2SAT prefers
to use the more accurate tracking accuracy to measure performance
instead of commonly used pointing accuracy, mainly because it
includes both the losses due to pointing and the polarisation
misalignments. The high tracking accuracy is a result of the C2SAT
gradient tracking method, a predetermination tracking parameter and
the 4-axes design, where the fourth axis refers to the cross-level
elevation. Higher accuracy results in: improved availability; more
effi cient use of shared lines and network bandwidth; and wider
operational area in the satellite footprint.
Faster System
The system is faster due to the gimbal design with AC
servomotors on each axis, and the C2SAT gradient satellite tracking
method on all axes. The system locks on the satellite within 6
seconds acquisition time, starting from its parking position. This
speeds up the transition from one satellite to another and results
in extremely fast recovery from sync loss.
Robust System
Because the gimbal design excludes the balancing
counterweight usually necessary in centre pole-based systems, the
servo motors on the axes are subjected to less torque. This also
leads to lower stress on the mechanical rig, which means reduced
maintenance costs and less down-time.
Accessories
A specially designed radome offers only 0.4 dB (normally
1.5 dB) attenuation. Space in the radome is sufficient to
accommodate an Air Condition device, for heat exchange and to keep
condense water at a minimum. An easy to use graphical user
interface (GUI) is provided which an operator with no previous
satellite experience can operate.

Simple to service and maintain
Simple service and maintenance is inherent to the mechanical
design.
