<p>This invention relates to an orientation measurement unit and in particular, this invention relates to an orientation measurement unit which consists of an attitude and heading reference system having Micro Electro Mechanical Systems (MEMS) sensor modules to determine the attitude of a set of unguided instruments and payloads. More particularly, this present invention also relates to an orientation measurement unit which is used to measure the attitude of a payload on-board a weather balloon. Furthermore, this invention also relates to an orientation measurement unit having the exact orientation of the detectors facing the sky in order to infer the nature of the obtained data and their respective sources. Moreover, this invention also relates to orientation measurement unit having the exact orientation of the detectors facing the sky in order to infer the nature of the obtained data and their respective sources and a software identifies the source of each signal detected at every instant of time.</p> |
