The primary mode of the attitude control system (idle, sunline, celestial). This data tells us whether the attitude control system is running or not.
A-0002 ACS Sub Mode
The secondary (sub) mode of the attitude control system (idle, sunline, celestial). This mode tells us whether the attitude control system is busy or not.
A-0040 Estimated Spin Rate
The spin rate (in rpm) estimated by the attitude control software from sun sensor data.
A-3708 Sun Cone
The number of degrees the Sun is off of the spacecraft spin axis. Usually this number stays within 45 degrees.
A-3701 Earth Angle
The number of degrees the Earth is off of the spacecraft spin axis. Usually this number stays within 45 degrees.
A-3110 Latch Valve State
This tells us whether the propulsion latch valves are open or closed. These valves separate the hydrazine fuel tanks from the thrusters.
