This instrument is designed for the highest reliability and uses a structure with redundant equipment in cold reserve mode. It includes two independent magnetometers with corresponding sensors assembled to form a small robust monoblock. Special sensor design maintains axial alignment after extreme shock loads. A user serial interface transmits output digital signals into the microsatellite control system. The interface is implemented as “inverse” current loop for minimal power consumption and maintains UART protocol. Both main and redundant channels of communication are galvanically insulated from other satellite system circuits. |
