INTRODUCING THE INTRAC-305
The
The
The system always tracks the satellite from the orbit model. The small movements of antenna pointing are only used to maintain and update the model.
By using the model to point the antenna the INTRAC system ensures that the antenna is always pointed accurately at the satellite. This is in contrast to Step Track systems where the antenna spends most of the time not actually pointing directly at the satellite.
The regular measurements made by the INTRAC ensure that changes in the apparent orbit, due to station keeping manoeuvres or other causes, are identified. The model is modified and refined to incorporate these changes and accurate tracking is automatically maintained. The INTRAC will automatically increase the measuring rate if necessary in order to obtain sufficient information on the changing orbit.
As the INTRAC tracks using its orbit model it will continue to track the satellite if the tracking signal is degraded or lost. The satellite position may be accurately predicted from the model for up to 72hrs without a tracking signal.
The INTRAC system provides this exceptional tracking performance and robustness for satellites with any inclination, at any look angle, even in the presence of severe beacon signal degradation entirely automatically. No operator intervention or parameter setting is required when conditions or satellites are changed.
