The designed calculator, ML-646XE-1UM, is used to compute meteorological balloon altitude it is the result of trade-offs involving basic measurement accuracies of the ground tracking system, ANTMQ-19, curvature of the earth corrections, geopotential altitude above surface, refractivity, and pitch and roll of the ground tracking system.
