牧星巡宇，立业兴邦
Aerospace Tianmu（chongqing）Satellite Technology Co.,Ltd, established in January 2023, is the core entity for low-Earth orbit satellite data application services under CASIC.
Tianmu is committed to building an extensive, low-cost satellite network with broad coverage, promoting the establishment and application of space infrastructure and strategic deployment. The company aims to secure a leading position in space-based information applications, with the goal of becoming a world class provider of space information application services.
Building a new meteorological analysis system based on future-oriented space infrastructure
The Tianmu constellation is establishing an occultation-based meteorological observation system composed of both sun-synchronous and low-inclination orbits. This system provides 24/7 global observation capabilities with dense coverage in mid-to-low latitudes. It comprehensively gathers environmental data from the Earth's surface to near space, utilizing predictive models to distill and integrate complex data into highly usable products.
Land surface data
Study land surface using GNSS scatterometry and precise altimetry (GNSS-R), to measure soil moisture.
Sea surface data
Study sea surface using GNSS scatterometry and precise altimetry (GNSS-R), to measure ocean wind speed and sea ice.
Atmospheric data
Monitor our atmosphere with precise GNSS radio occultation (GNSS-RO) soundings to improve global weather forecasting accuracy.
Ionospheric data
Monitor the ionosphere using measurements of electron density and scintillation to augment GNSS accuracy, providing new insights into weather changes.
Tianmu SpecificationsEquipped with GNSS occultation and ocean reflection detection payloads, it supports the BeiDou, GPS, Galileo, and Glonass navigation systems, providing powerful capabilities for acquiring global meteorological information.
