DIRECTV ® 's Digital Satellite Service (DSS) satellites. The
system is also fully compatible with KVH's TracNet
High-speed Internet System (for more information about

In-motion Tracking
The TracVision G4 uses a state-of-the-art actively stabilized
antenna system. Once the satellite is acquired, the antenna gyro
continuously measures the heading, pitch, and roll of your vessel
and sends commands to the antenna motors to keep the antenna
pointed at the satellite at all times.
