Downlink
and uplink
The communication going from a satellite
to ground is called downlink, and when it is going from ground to a satellite
it is called uplink. When an uplink is being received by the spacecraft at the same
time a downlink is being received by Earth, the communication is called
two-way. If there is only an uplink happening, this communication is called
upload. If there is only a downlink happening, the communication is called
one-way.

A template
is a ready made blank document, with placeholders for items like text and
graphics.
Templates
are very useful. They are the skeletons of a document with much of the format
of the document already laid out, for example headings, colour, fonts, tables
and text boxes already set up. They
speed up the creation of new documents because much of the design work has been
done for you.
Under each
of the tabs below are a number of templates of different designs. The one
previwed is a template that can be used in PowerPoint.

A wizard
is a feature in a package that guides you through a complicated task. A popular
use of wizards in general purpose packages is to take you, step by step,
through the process of setting up a document. This wizard guides you through
the stages involved in setting up a desktop publishing document.
Downlink
and uplink
The communication going from a satellite to ground is called downlink, and when it is going from ground to a satellite it is called uplink. When an uplink is being received by the spacecraft at the same time a downlink is being received by Earth, the communication is called two-way. If there is only an uplink happening, this communication is called upload. If there is only a downlink happening, the communication is called one-way.
DS1
has a constant downlink going to Earth sending little bits of information.
However, most of the communication is done two-way with the Deep Space Network.
