Sensor Development Thermospheric Neutral Wind Measurements

摘要

The final preparatory work toward the functional design of a flight sensor for neutral wind measurements has been completed. Extensive laboratory testing has been followed by digital control design that will allow the input drivers and the output currents to be assembled for delivery to the ground. A flexible format for energy discrimination in the retarding potential analyzer must allow for the expected geophysical variation in the velocity and temperature of the species. The instrument operation must also be synchronized to allow autonomous data reduction on the ground from a single packet of data.
