The National Time Service Center is located in the west of pucheng county City, Shaanxi Province. Four towers of more than 200 meters reach the sky, and there are spectacular antenna groups and transmitter rooms. These facilities have been stationed by the People's Liberation Army and later by the Armed Police Squadron. For a long time, people around you know that this is a secret unit, code-named "326". After 1980s, this China time service station gradually became known.
China is a developing country with a vast territory and a long coastline. At present, short wave time service is still an economical and practical millisecond precision time service method. The short-wave time service mode of National Time Service Center has many users in the fields of electric power, surveying and mapping, earthquake and communication. Pucheng time service department has BPM short-wave time service station, BPL long-wave time service station, BPC low-frequency time code test bed, transmission and broadcasting monitoring room and power station (maintaining a 35KV special substation and 65438+ 10KV high-voltage line).

Beijing time is the national standard time in China, which was produced in Shaanxi and released by Shaanxi National Time Service Center. In order to firmly grasp the "time" in their own hands, several generations of China researchers have repeatedly achieved "zero" breakthroughs in key technologies, and realized self-controlled timing technology, ranking among the world's advanced ranks.
In 1960s, Shaanxi Observatory, the predecessor of the National Time Service Center, was established by China Academy of Sciences at 1966 to provide time service for the whole country. Qi Guanrong, one of the first batch of 23 college students who reported to the Shaanxi Observatory, said that with the fighting spirit of "moving one stone at a time, one observatory must be moved out", the pucheng county Observatory in Shaanxi Province was built as scheduled and put into trial broadcast at 197 1, which enabled China to have the continuous time service capability of high-precision land-based short-wave radio stations with full land coverage.
