Design
The commercial telecommunications satellite SatMex-8 was manufactured by the California- based Space Systems / Loral company for the Mexican satellite company Satelites Mexicanos SA de CV. The satellite is made on the basis of the SS / L 1300 satellite platform with a service life of at least 15 years and is designed to act as a communication communications satellite for transmitting all kinds of data in the territory of Central North and South America. [2]
The satellite is equipped with two solar panels and a set of batteries, a three-axis spatial orientation system and a plasma propulsion system for correcting its position in geostationary orbit. The total satellite weight is about 5,475 kg. [2]
The payload module is 24 C-band transponders and 40 Ku-band transponders :
- C- band is represented by transmitters with a rated power of 65 W for broadcasting at frequencies from 24 MHz to 36 MHz in the global beam area (Hemi Beam) and allows covering the territory of South, Central and partially North America; [2]
- Ku-1 range is represented by transmitters with a rated power of 150 W for broadcasting at frequencies from 15 MHz to 36 MHz and 1-54 MHz in the zone of the NAFTA agreement and allows covering the territory of Central and partially North America; [2]
- Ku-2 range is represented by transmitters with a rated power of 150 W for broadcasting at frequencies from 7 MHz to 36 MHz and 1-54 MHz in the global beam area (Hemi Beam) and allows covering the territory of Central America;
- Ku-3 range is represented by transmitters with a rated power of 150 W for broadcasting at frequencies from 15 MHz to 36 MHz and 1-54 MHz in the restricted area of ββthe South American Beam and allows you to partially cover the territory of South America; [2]
Launch
On March 21, 2013, from the 39th launcher of the launch complex No. 200 of the Baikonur Cosmodrome, the Mexican telecommunication satellite Satmex-8 was launched using the Proton-M booster rocket and the Briz-M booster block.
