TECHNOLOGY TRANSFER OPPORTUNITY: Universal and automated Monte Carlo method code for uncertainty propagation in large volume metrology databases (GSC-TOPS-92)

NASA's Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses . THE TECHNOLOGY: A custom Monte Carlo uncertainty propagation routine was developed by NASA Goddard as a means to robustly propagate, analyze, and book-keep the uncertainty associated with spatially transforming targets and unit vectors between databases with common targets. A custom Monte Carlo uncertainty propagation routine was developed that fuses multiple measurements and their uncertainties from a network of different metrology instruments. The Monte Carlo error propagation routine generates N-different geometric best-fit transformations between two separate databases with at least 3 corresponding targets. Each of the geometric transformations involves simulating target measurements from the sum of the nominal targets and their randomly-drawn uncertainties. The user has the option of uninvolving common outlier targets as well as specifying the number of MC transformations to be used. The Monte Carlo error propagation method has been shown to be beneficial for propagating uncertainty through multiple James Webb Space Telescope (JWST) databases and for estimating transformation uncertainty for line-of-sight modeling scenarios where one or more targets may be omitted from a best-fit transformation. Typical run times for the Monte Carlo Transformation Uncertainty (MCTU) code range from 15 seconds for 10 targets to 2 minutes for several hundred targets on a 64-bit Windows 7 machine, using 1,000 Monte Carlo transformations. The MCTU software offers a robust approach to characterizing and propagating the uncertainty in transformed metrology database targets based on the uncertainty in a rigid body constellation of targets involved in the transformation.
