Designed for High Transmission Rates

The Innosat C-band is a high performance stabilised VSAT antenna that is designed to meet increased demands on transmission rate.  The antenna is easy to install as it is completely assembled and tested at factory level before delivery. No mechanical adjustments or weight balancing of the antenna itself is required during installation on site.

 

Reliable Satellite Communication

The Innosat C-band is a 4-axes marine stabilised VSAT antenna compatible with C-band satellites.  The reflector RF aperture is 2.4 metres.

 

High elevation problems are experienced with traditional 3-axes systems and occur 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 Innosat designed 4-axes solution 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 therefore does not experience any high-elevation problems.

This high reliability makes the Innosat antennas suitable for use as the main connection point as the system can carry large volumes of information without interruption.  Innosat’s proprietary tracking system identifies and finds any selected satellite within 6-8 seconds.

 

Better Accuracy

The system achieves superb high-tracking accuracy (only a tracking loss of +-0.1 dB), which is comparable to a fixed antenna.  Innosat prefers to use the value of tracking accuracy to measure performance instead of pointing accuracy, because it includes both losses due to pointing and RF beam misalignments.  The high tracking accuracy is a result of the Innosat proprietary tracking method, a predetermination tracking parameter and the 4-axes design, where the fourth axis refers to the polarisation-axle (only in linear).  Higher accuracy results in improved availability and more efficient use.

Faster System

The system is faster due to the gimbal design with AC servomotors on each axis, and the Innosat satellite proprietary tracking method on all axes.  The system locks on the satellite within 6-8 seconds acquisition time, starting from its parked position.  This speeds up the transition from one satellite to another and results in extremely fast recovery from sync loss.
