On the 11th, according to the official website of the International Telecommunication Union (ITU), China officially submitted a frequency and orbit resource application to ITU for the addition of 203000 satellites from December 25th to 31st, 2025, covering 14 satellite constellations, including low - and medium orbit satellites. According to statistics, this is the largest international frequency orbit centralized declaration operation in China so far. Among them, the Radio Spectrum Development and Technology Innovation Research Institute (hereinafter referred to as the "Radio Innovation Institute") has applied for two constellations, CTC-1 and CTC-2, with 96714 satellites each, totaling 193428 satellites, accounting for more than 95% of the total application. Other declaration entities include China Star Network, China Mobile, Yuanxin Satellite, etc. It is worth noting that this round of applications is no longer limited to traditional satellite operators, and includes entities such as radio innovation institutes, commercial aerospace companies, and basic telecommunications operators. Industry insiders believe that this large-scale application is expected to activate the entire industry chain of satellite manufacturing, launch, and operation, promoting the scale improvement and core capability breakthrough of China's aerospace industry. It is understood that according to the ITU Radio Regulations, deploying satellite systems using satellite frequency orbit resources generally requires a series of work such as satellite network declaration, coordination, registration, and maintenance to be carried out 2-7 years before the launch of the satellite. Declaring satellite network information to ITU is the first step for satellite operating units in various countries to deploy satellite systems, and it is also a mandatory procedure that must be followed according to radio regulations. As of now, multiple countries have applied for satellite network data with a satellite scale of over 100000 according to their own situations. Due to various factors such as international coordination of satellite frequency and orbit resources, system construction, and changes in market demand, in most cases, the actual deployment of satellites and technical parameters by relevant companies will undergo dynamic optimization and adjustment. According to relevant experts, satellite systems generally require a long time from international declaration and coordination of satellite network data, to satellite launch, system construction, service provision, and application promotion. The satellite network information declared by relevant units in our country this time is a routine operation to fulfill ITU related procedures and should be treated rationally. (New Society)
