EchoStar XVI Direct Broadcast Service Satellite, United States of America
EchoStar XVI is a direct broadcast service (DBS) satellite built by Space Systems/Loral (SS/L), for EchoStar Corporation. The satellite was successfully launched into the geostationary transfer orbit from the Baikonur Cosmodrome in Kazakhstan on 21 November 2012.
EchoStar leased the EchoStar XVI satellite to DISH Network for providing direct-to-home (DTH) broadcast services to DISH customers in the US.
The satellite is currently undergoing post-launch manoeuvres and will ultimately be placed at 61.5 degrees west longitude. EchoStar XV was launched in July 2010 and placed at the same orbital location. EchoStar XVI provides additional capacity at the same geostationary orbital location.
Design of EchoStar XVI satellite
EchoStar XVI is the eighth satellite designed and manufactured by SS/L for EchoStar. It is a high-power satellite with a launch mass of 6,258kg, which has been designed for a lifespan of 15 years. It is equipped with two deployable solar arrays and batteries.
The satellite was designed, assembled and tested at the SS/L factory at Palo Alto in California. It was transported to the Baikonur Space Centre in Kazakhstan in October 2012 for carrying out the launch operations.
1300 satellite bus for EchoStar XVI
EchoStar XVI is based on 1300 bus platform, which was designed and manufactured by SS/L. It is built on a proven space technology that offers high flexibility, longer mission life and higher power. It has a power capability ranging between 5kW and 25kW. It can support 12 to 150 transponders. The satellite bus was manufactured at SS/L's Palo Alto facility in California.
The Intelsat 21 communication satellite was successfully placed into the geosynchronous Earth orbit in August 2012.
The satellite bus contains a lightweight structure with high-strength. It is also equipped with stationkeeping subsystems, as well as superior command and control subsystems. It is equipped to lift off launch masses up to 6,700kg.
Launch of EchoStar XVI by ILS Proton Briz-M
EchoStar XVI was launched using Proton Briz-M rocket launcher, from launch pad 39 of Baikonur Cosmodrome. The satellite launching services were provided by International Launch Services (ILS). The satellite was developed and built by Khrunichev Research and Production Space Centre.
The launch vehicle has three stages. The total height of the Proton booster in all the three stages was 42.3m. The launch into the geostationary transfer orbit was done in a nine-hour and 12-minute mission.
EchoStar XVI communication capabilities
The satellite has 32 Ku-band transponders. It covers the continental US (CONUS) and spot beams.
A gold-plated silicon disc titled 'The Last Pictures' was attached to the satellite. The disc contains over 100 images of modern human history and is expected to last for billions of years in the future.
The project was conceived by Trevor Paglen, an American artist, and commissioned by Creative Time.
Ground station centres for EchoStar satellites
The ground control centres for the EchoStar satellite fleet are located at Cheyenne in Wyoming, and Gilbert in Arizona.
The EchoStar XVI satellite will be operated from the Gilbert broadcast control centre. The control centre has a floor space of 65,000ft2and is equipped with six 1,000kW diesel generators with underground fuel storage capacity of 30,000 gallons. It also features a 15,000 gallon condenser water storage tank.
The control centre is facilitated with 35 computer rooms, air conditioning units, and 750KVA UPS units. It also features a pre-action fire suppression system.
