High Resolution Signal Processing Module for Precision Position Sensors

This Phase II SBIR will create a new generation of position sensors with unprecedented performance in terms of dynamic range, accuracy, data rates and latency. Dramatic improvements in the performance of optical beam control systems for high precision pointing, tracking and lead-ahead targeting will follow. Jitter in line-of-sight image stabilization systems can be reduced by a factor of 20 relative to current state-of-the-art sensors. Phase II will include the full development of key component technologies. This includes the following: a radiation tolerant design for a custom IC for signal detection; a radiation tolerant 24 bit ADC hybrid circuit; implementation of a new self-sensing temperature compensation method; new algorithms for linearity error correction; and new approaches to self-calibration at the next assembly level. The system will be packaged in a small flight grade module with SpaceWire interface. It requires only a standard 28 VDC power supply. Two versions will be offered: a lower cost airborne version; and a radiation tolerant system designed to meet Level 1 quality requirements for space-based applications. By the end of Phase II the technology will be available at TRL 8. A flight-grade unit will be built and subjected to qualification level performance and environmental tests.
