The MATMOS Fourier Transform Infrared (FTIR) spectrometer is a concept instrument designed to measure the Mars atmospheric composition using solar occultation from orbit. MATMOS requires high sampling rate (up to 300 kHz), high dynamic range (up to 22 bits) data acquisition to record time-domain interferograms which get converted to spectra on-board the spacecraft. Our previous work presented a system...
The MATMOS Fourier transform infrared (FTIR) spectrometer is one of three scientific instruments on the previously proposed MARVEL mission. MATMOS requires computationally intensive floating-point signal processing to reduce the amount of data prior to downlink. With the goal of reducing design time and the size and weight of instrument electronics, this paper presents an FTIR spectrometry implementation...
A proposed Mars Scout Mission known as MARVEL is vying for the 2011 launch opportunity. One of its primary instruments, MATMOS, will produce large volumes of data in short, 3-minute bursts during its on-orbit observation of sunrise and sunset. The remaining orbit time of 112 minutes is available for on-board data processing to reduce data volume prior to downlink. This data processing relies heavily...
