Marine Satcom antenna (VSAT, C-band, for ships)

The C2SAT 2.4m C is the standard 4-axes marine stabilised VSAT antenna compatible with C-band satellites. Standard reflector diameter is 2.4m (94").

Reliable Satellite Communications

The 4-axes solution designed by C2SAT allows 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.

Better Accuracy

The system achieves superbly high tracking accuracy (only a loss of +- 0,1 dB), comparable to a fixed 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 efficient use of shared lines and network bandwidth
  • wider operational area in the satellite footprint.
