Abstract and Scope of Work

This paper describes the design of the analog section of a strapdown microelectromechanical (MEMs) six degree-of-freedom (DOF) inertial measurement unit (IMU) that is meant to be used as part of an avionics system for an amateur rocket. The design attempts to minimize sensor noise (which maximizes the IMU's performance) while being harshly constrained by cost, size, weight, and power consumption. Included in the design is the proposed hardware and software interface to a local microcontroller for use in a "flight computer with intelligent sensor nodes" avionics system.
