Session
Technical Session II: Systems, Buses
Abstract
American Microsat president Joseph A. LeBlanc will present the AVATAR Small Spacecraft System. The AVATAR Small Spacecraft System consists of the AVATAR satellite modules and the ground control and data collection facility. The AVATAR spacecraft is comprised of modules containing specific mission subsystems that are designed to work together or independently to satisfy mission requirements. Four modules provide payload space, control, propulsion and three axis stabilization. The different modules (described below) and the customer launch options will be discussed separately during the presentation. Common Services Module: The Common Services Module houses the spacecraft computer, the TT&C communications equipment, the attitude determination sensors, the spacecraft batteries, the power supply, and other optional subsystems. Propulsion Module: The propulsion module consists of thrusters and propellant stored in spherical tanks to maneuver the AVATAR satellite in orbit. Both cold gas and hydrazine systems are available. Three Axis Stabilization Module: The three axis stabilization module contains the subsystems needed for high-resolution three axis attitude determination and control. Payload Module: The payload module houses the customer payload. The dimensions of the payload module vary, depending on specific payload requirements. Payloads ranging from one to two hundred kilograms in mass can be carried.
