The highest detection accuracy of the earth’s magnetic field satellite in China – “Macau Science-1” , entered the predetermined orbit on May 21. TY-Space PST3S-H5 star tracker provides attitude determination service for it.
“Macao Science-1” is the world’s first low-latitude geomagnetic field and space environment scientific exploration satellite, adopting the “star A + star B ” combination observation mode. Developed by Northwestern Polytechnical University and served by TY-Space PST3S-H5 star sensor, the star B mainly to obtain space environment data such as solar X-ray radiation and medium-energy particles, and adopts the sun-oriented mode, while star A is mainly for high-precision detection of the earth’s magnetic field. Obtained from the combination of star A & star B, such as the Earth’s low-latitude regions & the Earth’s Magnetic Anomaly Area (SAA) over the South Atlantic Ocean, the Earth’s magnetic field, solar X-ray radiation, and energy particles, the data thereby reveal the distribution of the Earth’s magnetic field in near-Earth orbit, as well as the Earth’s magnetic field-solar radiation -The coupling law of energy particle distribution. “Macao Science-1” has realized the leap-forward development in the field of satellite high-precision magnetic field detection and multi-parameter combination observation technology in China.
PST3S-H5 is a high-precision star tracker with low power consumption and a fully autonomous system. It has the function of real-time image transmission on-orbit, and PST3S-H5 star tracker’s design can be customized for various applications.
