Receiver Field of View

What is the meaning of Receiver Field of View ?

It is the angular range of the sky that the user terminal can actively scan and maintain communication with satellites. It uses a large constellation of low Earth orbit (LEO) satellites moving quickly across the sky, the dish must constantly switch connections from one satellite to another.

A wide FOV (typically around 100° or more) allows it to detect and connect to multiple satellites within that region, ensuring smooth handoffs and continuous internet service. The dish uses phased-array antenna technology, which electronically steers its beam without physically moving, to track satellites across its field of view. However, the performance depends heavily on having a clear view of the sky — obstructions like trees, walls, or roofs that block any part of the FOV can cause brief service interruptions or reduced speeds. In essence, the receiver FOV defines how effectively your dish can “see” and maintain stable connections with Starlink’s moving satellites.
