Intelsat 27 Communication Satellite Overview

Intelsat 27 is a high-powered communication satellite designed to provide telecommunications services to various regions around the world. Launched in 2012, it is positioned at 43° West longitude, offering coverage to the Americas, Europe, and Africa.

With a mass of approximately 6,000 kg, Intelsat 27 is a significant addition to the Intelsat fleet. Its advanced technology and design enable it to deliver high-quality video, voice, and data services to a wide range of customers.

The satellite has a powerful payload capacity, with 26 C-band transponders and 10 Ku-band transponders.

Intelsat 27 was a satellite ordered in 2009 as part of a four-satellite package. It was designed to provide hybrid C- and Ku-band services for media and network customers.

The satellite had a unique feature - a 20 × 25 kHz channel UHF payload for government applications. This payload was digitally tunable and interoperable with existing terminals.

Intelsat signed an agreement with Boeing Space and Intelligence Systems to manufacture the satellite in August 2010. The satellite was powered by two solar wings, each with three panels of ultra triple-junction gallium arsenide solar cells.

Here's a summary of the satellite's key features:

The satellite was intended to be placed in the Atlantic Ocean Region as a replacement for the Intelsat 805 satellite.

The Intelsat 27 satellite was designed and manufactured by Boeing Satellite Systems, with construction starting in August 2010.

The satellite's bus platform was a 702MP model, first introduced in 2009 by Boeing. It had a liftoff mass of 6,203kg and measured 6.9m high and 9.25m wide.

Intelsat 27 was powered by a solar array consisting of four panels of ultra triple-junction gallium arsenide solar cells. The satellite was designed to have 11.8kW power at end-of-life.

Intelsat 27 was a satellite designed for media and network customers, with a hybrid C- and Ku-band design. It was also equipped with a 20 × 25 kHz channel UHF payload for government applications.

The satellite was built on a 702MP bus platform manufactured by Boeing, first introduced in 2009. It had a liftoff mass of 6,203kg, making it a significant structure.

Intelsat 27 was powered by a solar array, which consisted of four panels of ultra triple-junction gallium arsenide solar cells. The satellite was designed to have 11.8kW power at end-of-life.

Here are some key specifications of the Intelsat 27 satellite:

Intelsat 27 was controlled by a hybrid bi-propellant propulsion system, designed for a lifespan of more than 15 years.

The design of Intelsat 27 was a collaborative effort between Intelsat and Boeing Satellite Systems, with the contract awarded to Boeing in 2009.

The satellite used a 702MP bus platform manufactured by Boeing, which was first introduced in 2009. This platform provided the foundation for the satellite's design and functionality.

Intelsat 27 had a hybrid C- and Ku-band design, making it suitable for various communication needs. The satellite's payload was also augmented with a 20 x 25 kHz channel UHF payload for military communications.

The satellite was 6.9m high and 9.25m wide, with a liftoff mass of 6,203kg. Its payload was powered by a solar array consisting of four panels of ultra triple-junction gallium arsenide solar cells.

The satellite's propulsion system was a hybrid bi-propellant system, which was designed to control the satellite's movements and maintain its position in orbit.

Intelsat 27 was launched on 26 September 2013 from the Baikonur Cosmodrome in Kazakhstan using a Proton Breeze M rocket. This launch marked a significant milestone in the satellite's journey.

The satellite was placed into a geostationary transfer orbit (GTO) at an altitude of approximately 36,000 kilometers above the equator.

Intelsat 27's orbit is synchronized with the Earth's rotation, allowing it to remain stationary over a specific location at a fixed longitude.

The Zenit-3SL rocket was a reliable choice for launching the Intelsat 27 communication satellite.

This rocket, built by Yuzhnoye Design Bureau and operated by Sea Launch, had three stages to ensure a smooth and efficient launch process.

The first stage of the rocket was manufactured by Yuzhnoye, and its separation from the rest of the vehicle was completed in about two minutes and 30 seconds after liftoff.

The second stage involved a six-minute burn, followed by separation from the upper stage.

The Block DM-SL upper stage was made by RKK Energia and played a crucial role in the final minutes of the launch.

The third and upper stage launch involved an eight minutes and 41 seconds burn into the mission, after which the spacecraft separation would occur.

The payload fairing, produced by Boeing, protected the satellite during the intense heat of launch and helped it reach its intended orbit.

The satellite control centre is a crucial component of the launch and control process. It's where the satellite is monitored and controlled after launch.

Kratos Defense & Security Solutions was awarded a contract to deliver command and control equipment and fleet management systems for Intelsat 27 satellite operations. This contract was a significant step in establishing a robust control centre infrastructure.

The satellite was to be controlled from the monitoring and control centre headquarters in Washington DC and Long Beach, California. This dual location setup allows for more efficient and effective control.

The operation centres for the satellite were to be fully equipped with sophisticated facilities and capabilities for carrying out operations of entire third-party satellite fleets. This includes tracking, telemetry, and command (TT&C) stations and mission control centres (MCC) in various locations.

The ground communications infrastructure included the highly secure IntelsatONE network, a state-of-the-art platform for satellite communications. This secure network is essential for reliable and efficient communication with the satellite.
