Intelsat 11 was launched on May 19, 2007, aboard a Proton M rocket from the Baikonur Cosmodrome in Kazakhstan. The satellite was deployed into a geostationary transfer orbit.
The satellite reached its final geostationary orbit and was operational by May 23, 2007. This allowed Intelsat 11 to begin providing commercial communications services to customers around the world.
Intelsat 11 is positioned at 302° East longitude, where it provides coverage to Africa, Europe, and the Middle East. This strategic location enables the satellite to offer a wide range of services, including television broadcasting, telecommunications, and internet connectivity.
The satellite's high-powered transponders enable it to deliver high-quality signals to a large number of receivers, making it an essential part of the global communications network.

Launch and Deployment
The Intelsat 11 satellite was launched into orbit on October 5, 2007, aboard an Ariane 5 rocket from the European space launch complex in French Guiana.
The launch was a success, with the satellite and its companion Optus D2 spacecraft reaching their initial orbit as planned. Both satellites were built by Orbital Sciences Corporation.

The Ariane 5 rocket delivered the satellites into their initial orbit, and they are now performing a series of orbit-raising burns to reach their final position in a circular orbit approximately 22,300 miles above the Earth.
The Intelsat 11 satellite will provide both C-band and Ku-band services, delivering C-band services to Intelsat's customers in the continental United States and serving as DirecTV Latin America's Ku-band downlink for coverage of Brazil.
The satellite will undergo several weeks of in-orbit testing prior to the commencement of commercial service.
The Optus D2 satellite will be positioned at 152 degrees East and has a design life of 15 years, providing direct TV broadcast, Internet, telephone, and data transmission services for Australia and New Zealand.
The launch of the Intelsat 11 and Optus D2 satellites marked the first time that two of Orbital's GEO satellites were launched aboard the same rocket.

Spectral Analysis
The spectral analysis of Intelsat 11 at 43.0°W reveals some interesting results. The MERp (Modulation Error Ratio) is 9.5 dB, indicating a high level of signal quality.
A gain margin of more than 3 dB was consistently measured, which is a good sign for a reliable signal. The peak amplitude MER was found to oscillate within a range of +/- 0.2 dB, which is a relatively small variation.
The spectral analysis also includes information about the various channels carried by Intelsat 11. For example, the 3 717/3 745 V channel is used for TP AE1C North & South America, Europe, and other services.
