Page 3: Introduction
Introduction The stabilized SpaceCom IP321 Maritime Antenna is designed for use with the Thuraya IP terminal. The SpaceCom IP321 Maritime Antenna is a 3-axis constant gain antenna designed for maritime use. It is an autonomous satellite tracking antenna using a patented beam squint technology and built-in control software to acquire the satellite and stabilize the antenna using a tracking beacon from the Thuraya satellites. -

Figure 5. Connecting to the Thuraya IP terminal via the active external antenna connector. The DC cable of the Power Supply, AS03951 is connected to the vessels power supply with specifications defined in Section 3. Ensure that the polarity is correct. The DC step-up converter in the Power Supply, AS03951 is isolated from the vessel’s 0V. -
Page 13: Operating The Antenna
In certain areas both satellites are visible and therefore the antenna can track either of them, but only one of them will allow the Thuraya IP to connect to the network. The area with both satellites visible is from longitude 60° East to 110° East. - Page 14 AS03951. This will redirect the antenna to track the beacon of the other satellite visible. It is not necessary to power off the Thuraya IP terminal.
