Clear you doubt regarding gsat 10 test signal and tata sky.
We all know, tata sky's future is totally depend on gsat 10. When i check some record of isro, i found intersting things. There is schedule after sat launch. Such as orbit raising, solar panel deploy, lock position, test signal and may more activity. Isro follow a fix schedule after satellite launch. Isro deployed BHEL's solar panel on 18 october. In general they switch on payload of gsat 10. For ex. You can check recent record of GSAT 8 and INSAT 4B. In case of insat 4b. It launch in 12 march and handover to dd in june 1 . Same in case of Gsat 8 launch on 21 may and test started in 15 julay. I research on isro's record.. So dont worry channels will be added within 1 month. The test signal of gsat 10 will be found around 20 november. I am very sure.
