The AD&C system determines
and controls the angular orientation (or direction of pointing) of
the spacecraft. This section discusses the Dawgstar team's choice of active
of telemetry data, uplink of commands from ground control, and crosslinks with
other ION-F nanosatellites requires a high degree of communications commonality
between ION-F partners.
The C&DH system is a
combination of software and hardware that manages the subsystems of the UW
The ION-F group will
fly in formation during the mission lifetime. This section discusses the
characteristics of formation flying and ground track options for the
The G&N subsystem
determines the position and velocity vectors of
the satellite as a function of time. These data can be used to calculate
the orbit of a satellite.
nanosatellite will be powered by a series of solar panels and batteries.
