Paper Abstract

Previous papers have described the concept behind the MightySat II.1 program, the satellite' Fourier Transform imaging spectrometer's optical design, and the design for the hyperspectral imaging payload. Initial qualification testing of the payload has been completed. All component level qualification tests have been finished. The solid block optics, interferometer, camera and telescope where all successfully tested and a payload Critical Deign Review was passed. Early optical testing of the monolithic interferometer has shown that it has the designed spectral resolution of less than 100 cm-1. Bench testing of a custom VME data interface board that operates the sensor in a variety of spatial and spectral resolution modes can transfer data satisfactorily at data rates up to 24.3 Mbytes/sec over a VSB bus to spacecraft solid state memory. Problems in manufacturing the hardened C-40 processors has caused a change to an unhardened version of the C-40 using tantalum foil for protection. This still allows all hyperspectral 'smart' imaging spectrometer demonstrations including a 10:1 data compression technique. The payload is scheduled to be delivered in April 1999 for integration on to the spacecraft bus.
