During teleoperation in space, there are two major sources of performance degradation: (1) spatiotemporal displacements in visual feedback; confounded by (2) microgravity effects, attributable to kinetic and inertial properties of large masses maneuvered in low gravity. Both sources contributed to the Progress-Mir collision in 1997. This report describes findings from two sets of studies directed at modeling possible effects on teleoperation tracking performance of spatial, temporal, and microgravity perturbations in visual feedback presented to the teleoperator. In the first set of studies, effects of both temporal and angular displacements in visual feedback on control of tracking behavior by individual subjects were evaluated under conditions of both continuous pursuit and discrete movement tracking.

Today's digital avionics systems leverage the use of the Embedded COTS (Commercial Off The Shelf) hardware to fit the need of small form factor, low power, reduced time to market and reduced development time with efficient use of DO-254 for compliance of product. COTS modules are entering in digital avionics systems such as COM (Computer On Module)/SOM (System On Module)/SIP (System In Package) with huge advancement in semiconductor and packaging industry. In today's scenario COTS are very useful for DAL (Development Assurance Level) C and below as the efforts on compliance for DAL A and B are huge. This paper proposes to use these for DAL A and B as well, where one can get enormous benefit on efforts of compliance and time to market. This paper makes an attempt to explain the current scenario of the Embedded COTS usage in Avionics Systems.
