August1-August 3 1 is the adjustment period of satellite transfer: satellite radio and television users adjust their reception according to the technical parameters and adjustment methods provided by radio and television departments.
August1-September 24th is the concurrent period of the old and new satellites: both the old and new satellites send radio and television programs. After September 24, the original satellite will stop launching.
Two. A program transmitted by satellite
1, zhongxing 6B satellite (east longitude 1 15.5 degrees): CCTV (1- 12)/ Music/News/Children, China Education, Anhui, Jiangxi, Jiangsu, Gansu, Tianjin, Beijing.
2. Xinnuo-3 satellite (east longitude 125 degrees): CCTV (1-3, 5-8,1kloc-0/2)/Music/News/Children, Guangxi, Guangdong, South, Shenzhen, Heilongjiang.
3. Asia-Pacific Satellite 6 (East longitude/KOOC-0/34 degrees) Ku band: CCTV-/KOOC-0//2/5/6/7/8//KOOC-0/0//KOOC-0/2/children, Inner Mongolia, Yunnan.
Third, the adjustment method of receiving antenna and receiver
Due to the change of the orbit position of the new satellite, it is necessary to correctly adjust the elevation angle, azimuth angle and feed polarization angle of the ground satellite receiving antenna in order to receive satellite signals normally. Move the antenna up and down when adjusting the elevation angle; During azimuth adjustment, the antenna moves left and right on the horizontal plane; The feed polarization angle adjustment is to horizontally rotate the tuner in the antenna feed tray.
Adjust the sequence first, adjust the satellite receiver, and set the pre-received program parameters; Then adjusting the polarization angle of the tuner; Then adjust the pitch and orientation of the satellite receiving antenna to determine the best position; It is also necessary to fine-tune the polarization angle of the tuner to confirm the best position; Finally, tighten the bolts and fix them.
CCTV-1 and anhui tv, which originally received 3S satellite signals from Asia, will adjust their reception of 6B satellite signals from China.
Adjustment of receiving antenna: the azimuth angle of the original receiving antenna rotates eastward 16-20 degrees; The elevation angle of the receiving antenna increases upward by about 65438 0 degrees; Fine-tune the polarization angle of the feed.
Adjustment of receiver: The operating interface and menu of different manufacturers and models of satellite receivers may be different, and the parameter names will be different. Find the setting page of "receiving frequency, symbol rate, polarization mode and FEC" through the menu operation, and you can adjust the parameters of the program received by the receiver. Enter the parameters correctly through the operation of the receiver panel and the remote controller, and then press the "OK" or "Search Program" button to find the required program.
Fourth, service information.
The State Administration of Radio, Film and Television (SARFT) has compiled an operation manual for satellite radio and television switching users' receiving equipment, which has detailed instructions on satellite downlink parameters and adjustment of receiving facilities. Users can download from the website of Planning Institute of SARFT (), the website of Anhui Radio and Television Bureau () or the website of Wuhu Municipal Government as required.
The Municipal Radio and Television General Station and China Broadcasting Cable Wuhu Branch provide technical consulting services for satellite transfer and adjustment. The telephone numbers are: City Radio and Television General Station 311701333 9236544, and China Broadcasting Cable Wuhu Branch 3 1 17087.
