Adjustment to Satellite Coverage and Band Width for CCTV International in the Western and Central Parts of Africa

With the development of CCTV’s multi-lingual overseas service, the satellite coverage and bandwidth in Africa is changing. A more powerful KU band of Eutelsat-W7 will replace signals from IS-10 and IS-1R.

W7（El 36°）has begun transmitting CCTV-4/9/F signals. CCTV users in the western and central parts of Africa who used to receive programs via IS-10 or IS-1R can continue to receive CCTV programs after they adjust the angles of their antenna and parameters of their receiver. Those who have switched to W4 need to readjust the reception parameters. CCTV4/9’s temporary signals on W4 will stop issuing on February 15, 2010. See Table 1 for specifications on W7 parameters.

Satellite	Beam & Band	Orbit of Satellite EL	Down Link Frequency (MHZ)	Down Link Polarization	Symbol Rate (Ms/S)	Forward Error Correction	Channel	Coverage Area
Eutelsat W7	South of Sahara (Ku)	36°	11938	H	27.5	3/4	CCTV4/9	Western and Central Parts of Africa
Eutelsat W7	South of Sahara (Ku)	36°	11862	H	27.5	3/4	CCTV-F	Western and Central Parts of Africa

IS-IR(WL 45°) has now stopped broadcasting CCTV International. IS-10 (EL 68.5°)will stop transmitting CCTV-4/F) from February 1, 2010. CCTV-9 will remain on IS-10, but with some changes to downlink frequency. (See Table 2) 

Satellite IS-10	Downlink Frequency (MHz)	Symbol Rate (Ms/S)	Forward Error Correction
Before Adjustment	4087.25	9.375	3/4
After Adjustment	4064	19.85	7/8

 
CCTV International viewers please adjust your satellite parameters accordingly.
