pointing information in the satellite modem. If you answer yes, the modem exits
pointing mode. When the modem finishes downloading the pointing
information, the DAPT2 displays a Pointing Done message.

Pointing Done
message on the DAPT2. Do not
remove the DAPT2 until you see the Pointing Done.
The following screens show the progression of pointing on the Terminal Installation
screens.
Coarse and fine pointing
Coarse pointing refers to pointing the antenna in the general direction of the Jupiter
satellite so that the antenna can acquire the satellite signal. Fine pointing refers to
refining the antenna adjustment to point the antenna as accurately as possible.
Figure 19 shows fine and course pointing in progress. Once pointing is completed,

Pointing validation
Once you have finished coarse pointing, use the DAPT2 to fine point the antenna.
The Pointing Validation screen (Figure 19) shows the validation in progress.
Ranging
Ranging occurs when the HT1000 measures the distance to the satellite to calibrate
transmit power and timing. Once ranging is complete the HT1000’s transmit and
receive signal are synchronized to the satellite for optimal transport service.
Once the ranging process finishes, registering the modem begins automatically. See
Chapter 5 –
Registering and commissioning the satellite modem on page 39 for
details on registering and commissioning the modem.
