The modeling and simulation of the Tether Dynamics Explorer (TDE) tension sensor

A three-axis tension sensor for a tethered satellite system is modeled and simulated. The design uses an aluminum cross fixed at each end with a rod mounted at the center. Semiconductor strain gauge bridges mounted on the cross resolve the tether tension into three orthogonal components. The model incorporates the effects of temperature on the strain gauges. The response of the sensor to a range of temperatures and tensions is simulated, and a method of thermal compensation is proposed
