Session

Session IX: Science and Exploration

Abstract

A solid state boron- ion implanted silicon Charged Particle Detector (CPD) was designed, built, and tested as one of the payloads for a Stanford University/Lockheed Martin Cubesat (10cm cube, 1 Kg) project intended for a low earth orbit. Design drivers to be discussed will include cost, size, mass and schedule. Two detectors were utilized with shielding to allow for two separate energy ranges to be detected. Stanford Research Institute facilities were used for testing. Design considerations will be discussed relating to tuning of the electronics for various low earth orbit altitudes, along with matching voltage requirements for the electronics with a low power, 3.7 Volt spacecraft bus (1 watt). Other payloads include a developmental sun sensor and Honeywell 3 axis solid state magnetometer. Overall cubesat development will also be discussed, including structure, communications, power, and processor. Testing techniques and current results will be shown for this ongoing project.
