For demonstration purposes, the paper focuses on two specific radiation effects implemented in a MOSFET device model. These two effects were chosen in order to illustrate two differing forms of model development. The first form takes existing device models and modifies the equations and/or variables already existing within that model to achieve the required results (behavioral modification). The second form adds completely new equations and variables to existing device models (behavioral augmentation). The MOSFET (1) threshold voltage shift due to total ionizing dosage (TID) and (2) leakage current increase due to TID, are two major device effects that fulfill both of these requirements. Voltage shift and leakage current are critical design issues in rad-hard electronics and space environments. The threshold voltage shift effects are implemented through the modification of device model equations, while leakage current increases are implemented with added behavioral macros to the model topology, thus fulfilling the second requirement. The use of the modified compact MOSFET model is illustrated in the simulation of an op-amp based filter. Gain and frequency shifts can be observed and compared as the circuit absorbs differing amounts of TID.","PeriodicalId":208052,"journal":{"name":"2004 IEEE Aerospace Conference Proceedings (IEEE Cat.

One issue with using COTS lies in the difference between their specified operating temperature range (-55/spl deg/C to125/spl deg/C for military components) and the temperatures observed at the surface of Mars (-120/spl deg/C to 20/spl deg/C). To compensate for the difference between these temperatures, most of the electronics are placed in a central warm-electronics-box or WEB. In some cases, such as the distributed control system for the actuators, the electronic assemblies that are to be placed on or near the motors are outside of the central WEB. The experimental search consists of two steps. First, a short functional/non-functional test at -120/spl deg/C is used to identify and narrow down the number of candidate COTS that can work at very cold temperatures. More extensive characterization of the parts that passes the short test is performed to determine the operating margins and estimate the thermal cycle life capability for the COTS parts. Finally, the operating margins of the COTS parts are published as a set of specifications.","PeriodicalId":208052,"journal":{"name":"2004 IEEE Aerospace Conference Proceedings (IEEE Cat.

One of the technologies being developed is the Formation Flying Interferometer (FFI). The FFI is envisioned to consist of up to seven spacecraft, each with an infrared telescope, flying in precise formation within /spl plusmn/1 cm of pre-determined trajectories for synchronized observations. The spacecraft-to-spacecraft separations are variable between 16 m and 100 m during observations to support various interferometer configurations in the planet-finding mode. The challenges involved with TPF autonomous operations, ranging from formation acquisition and formation maneuvering, to high precision formation flying during science observations are unprecedented for deep space missions. To meet these challenges, the Formation Sensor Testbed (FST) under the TPF technology program develops and demonstrates the key technology of the formation acquisition sensor. Key performance targets for the acquisition sensor are an instantaneous 4/spl pi/-steradian field of view and simultaneous range and bearing-angle measurements for multiple spacecraft with accuracy better than 50 cm and 1 degree, respectively. This paper describes the TPF FFI mission concept, the requirements for the acquisition sensor, design trades, the resulting sensor, and the technology to be demonstrated by the testbeds.","PeriodicalId":208052,"journal":{"name":"2004 IEEE Aerospace Conference Proceedings (IEEE Cat.
