how can we communicate with the outside world in the deserted desert or isolated mountainous areas? satellite communication is highly praised for its wide coverage, long communication distance, no environmental restrictions and high communication quality, but its high cost makes many people stay away from it.
on september 2, news came from the chongqing development and reform commission that the "solar battery array" innovatively developed by chongqing kaituo satellite technology co., ltd. (hereinafter referred to as "kaituo satellite") will greatly reduce the cost of satellite development and help build "satellites that everyone can afford."
taking china telecom's "mobile phone direct connection to satellite" service as an example, the direct connection to satellite service fee of 10 yuan per month only includes 2 minutes of voice calls, which is equivalent to 5 yuan per minute.
"why is the price of satellite communications so high? it is mainly because the chip cost, hardware and software adaptation cost, satellite construction and maintenance cost, etc. are all high." according to the relevant person in charge of kaituo satellite, solar arrays are satellite energy equipment and are one of the core components with the highest threshold and highest cost in satellite development.
the price of traditional triple-junction gallium arsenide solar arrays is as high as over 100w per square meter. since 2020, kaituo satellite has continued to tackle tough problems and independently developed the industry's first fully automated production line for solar arrays, and built a 2,500-square-meter ait hall for satellite core products, integrating production, assembly, testing, and experiments, with an annual production capacity of 200 satellite components. with 50% of the development cost and 30% of the development cycle of traditional aerospace, the product fundamentally solves the contradictions and pain points of the demand for stand-alone microsatellite products, and has good international competitiveness. the company currently produces a total of "5 types and 27 stars" of solar array products in orbit, and the products are in good operating condition in orbit.
kaituo satellite's satellite core component development technology is at the leading level in the industry, and the independently developed satellite core components provide important support for the development of the entire satellite. in the future, the company will continue to develop high-performance, low-cost, short-cycle micro-satellite core components and entire satellite products, build a high-performance remote sensing satellite constellation, realize the consumer-level commercial application of remote sensing satellite data, and let satellite technology benefit thousands of households.
the solar array for satellites is just a microcosm of the emergence of superior products from aerospace information enterprises in chongqing. a relevant person in charge of the chongqing development and reform commission said that chongqing is currently focusing on building a pilot zone for large-scale application of beidou, and will hold the 2024 international ecological conference on aerospace information industry from september 2 to 4 to help the high-quality development of the aerospace information industry.
