Is it 93.6E or 80.5E?

As per some sites Insat 4B is yet to be moved to it's final location (93.5E). ISRO is testing the satellite at 80.5E.

LynSat still shows 80.5: www.lyngsat.com/in4b.html
Real time satellite tracker also shows the location as 80.5E: www.n2yo.com/?s=30793

Don't know which one is correct.

Dear

Its not there

I have tuned to the TP but its empty

Its still not @ her final destination.

Fake news .... Some one has just updated at SatcoDX3 ....

Bangalore, April 11: The Indian Space Research Organisation's latest communication satellite INSAT-4B has become fully operational and the spacecraft will reach its final location tomorrow, the organisation announced today.

"Within one month (of the launch), we have made it fully operational," ISRO Chairman G Madhavan Nair told reporters here.

The 3,025-kg INSAT-4B carrying 24 transponders was successfully launched by an Ariane rocket from Kourou in French Guyana on March 12.

After placing the satellite in near-geosynchronous orbit in subsequent days, the deployment of two solar panels and two antennas was successfully completed. The tests have since been completed.

"The satellite is being moved to its final location of 93.5 deg E logitude, where it would be arrested tomorrow", Nair said.

Soo Tomm it would be in its own position.

Hi!
DD Direct plus DTH service will be migrating from NSS-6 at 95° E to INSAT 4B at 93.5° E, expected to be operationalised in May end 2007. However, the exact date of migration would be intimated in due course.

In this regard interested public STB dealers and Cable Operators should be in readiness for the migration. They would be required to reorient their receive PDAs and incorporate necessary changes in their SET TOP BOXES accordingly on the day of migration.

Pl. visit http://www.ddinews.gov.in/DTH

Hi bro, Good news, Keep it up.

Insat 4B was declared fully operational at the end of last week:

MUMBAI: A month after Insat-4B was lofted into space from French Guiana, the Indian Space Research Organisation's latest communication satellite has become fully operational.

The spacecraft reached its final location of 93.5 deg E longitude on Thursday.

Within one month (of the launch), we have made it fully operational," Isro chairman G Madhavan Nair told reporters in Bangalore on Wednesday.

Insat-4B was successfully launched by Ariane-5 ECA on 12 March from Kourou, French Guiana. Following its launch, a series of orbit-raising operations were conducted to place the satellite in its near-geosynchronous orbit. After those operations were completed, the deployment of its two solar panels and two antennas was carried out.

Insat-4B carries the following payloads:

12 Ku- band 36 MHz and 27 MHz usable bandwidth Transponders (9 and 3 numbers respectively) employing 140 W TWTAs to provide an EIRP of 52 dBW over the footprint covering Indian main land.

2 C-band 36 MHz bandwidth transponders employing 63 W TWTA to provide an EIRP 39 dBW with expanded coverage encompassing Indian geographical boundary, area beyond India in southeast and northwest regions.

Kalanithi Maran's Sun Group has booked seven Ku-band transponders on Insat-4B for its soon-to-launch DTH service Sun Direct, while Prasar Bharati's free-to-air (FTA) package DD Direct Plus has booked five.

Sun will be using MPEG-4 technology that will allow it to compress more TV channels per transponder. While MPEG-2 can pack in around 12 channels, the advanced compression technology will be able to accommodate over 20 channels.

Sun may consider itself lucky that the launch of Insat-4C satellite failed in July 2006 after the rocket carrying it veered off course and exploded. Sun had booked six Ku-band transponders (and one more for digital satellite news gathering) on it for its DTH service.

By being located on the same satellite, Sun's subscribers will be able to access DD Direct's channels without it having to separately put them on its transponders

Can Sun's MPEG-4 receivers decode DD's MPEG-2 channels? I hope MPEG4 recievers are backward compatible.

It has to be.
By the way somebody has noticed any test signals?
Satcodx has listed with 11.111 V test signal, as posted by the raj but no info of SR.

I don't think the Satcodx information is reliable. Satcodx was showing this information even before INSAT 4B was moved to it's final location.

**Hareesh** · 24-04-2007

Can somebody pointed to INSAT 4B check the following parameters and post the response?

TRANSPONDER FREQ: 11197
SR: 3.330 MS/s POLARITY: V
V-PID: 4194 A-PID: 4195
PCR-PID: 4194

Members hooked to the C band of Insat 3A can test these Ku band TPs with offset LNB.DD wont be starting the trnsmsn abruptly on June 1 but the test transmission has to start soon.There is no info reg the test trnsmn even on DD site.Members with the above setup can test these TPs and post the outcome.

**geeky1** · 27-04-2007

i get 60% strngth 70% quality with zenega and dish pointed at 95e.

sorry cant chck for pic/aud, only sig strngth/qual

Are you getting atleast DD channels? If yes, I will get the orientation changed.

Has test transmission started on these transponders? I don't think so. I tried yesterday and did not get any signal on these TPs.

These transponders are the ones which DD Direct+ is going to use. Does someone have details of the remaining 7 transponders which will be used by Sun DTH?

**member91040** · 14-05-2007

Insat 4b no signal, Now presently....! Before it was there...!

athavale · 15-05-2007

Latest update on http://www.ddinews.gov.in/DTH/DTH_Migration

NEW : Shutdown for shifting of DD Direct Plus from NSS-6 to INSAT 4B

DOORDARSHAN DTH SERVICE DD DIRECT PLUS ON NSS-6 SATELLITE WOULD
BE MIGRATING TO INSAT 4B. IN THIS REGARD THERE WOULD BE SHUT-DOWN
OF DTH SERVICE BETWEEN 2200 HRS. ON 31ST MAY 2007 AND 0600 HRS ON 1ST JUNE 2007.

nmohanraj · 15-05-2007

Can you specify the LNB frequency for INSAT-4B migration from June 1st ?
