Launch Services for Telstar 12 VANTAGE

Mission Overview

MHI's customer for the Telstar 12 VANTAGE mission is Telesat, a leading global satellite operator. In this flight, the H-IIA launch vehicle will deliver the Telstar 12 VANTAGE satellite to a Geosynchronous Transfer Orbit (GTO).

Mission Description - H-IIA F29 / Telstar 12 VANTAGE

The H-IIA launch vehicle configuration for the Telstar 12 VANTAGE mission is H2A204 / 4m payload fairing with the upgraded second stage configuration (KOHDO-KA). The H-IIA F29 will lift off from Launch Pad No.1 (LP1) at Yoshinobu launch complex in the Tanegashima Space Center, southern part of Japan. First pair and second pair of Solid rocket boosters (SRB-As), payload fairing and first stage are planned to be separated at 127sec, 130 sec, 205 sec and 408 sec from liftoff, respectively. 2nd stage engine 1st cutoff (SECO1) will occur in the visible range of the Ogasawara ground station. 2nd burn of 2nd stage is planned around the equator. Following a long coast, the 3rd burn of 2nd stage is conducted around apogee. Then, Telstar 12 VANTAGE is separated in the visible range of the Santiago ground station approximately 4 hours, 27 minutes from liftoff.

Satellite Payload

Telstar 12 VANTAGE

logo: Telesat

The satellite user community has long valued Telesat’s Telstar 12 for its ability to seamlessly connect the Americas to Europe and the Middle East from its highly prized orbital location of 15° West.

Now with Telesat's new Telstar 12 VANTAGE coming to 15° West, satellite broadband customers in mobility, government, oil & gas, and enterprise markets will have greatly improved coverage options between EMEA and the Americas through a combination of high throughput beams and broad regional beams. Telstar 12 VANTAGE will have a powerful new Brazil beam providing full coverage of Brazil along with a new dedicated beam over Sub-Saharan Africa.

Key advantages of Telesat’s Telstar 12 VANTAGE satellite

  • Optimized to meet growing demand of mobility markets - maritime and aero - over the Mediterranean, North Sea, the Caribbean, and the South Atlantic
  • Superior performance to meet increasing needs for bandwidth among oil gas, enterprise, government users and broadcasters
  • Broad regional beams combined with high throughput spot beams allow greater flexibility in network design
  • Improved efficiencies with lower costs per bit
  • Backward compatibility with existing Ku-band terminal equipment


Airbus Defense and Space


Up to 52 Ku-band 36 MHz equivalents, plus additional spot beam capacity


H-IIA Launch Vehicle H2A204

Launch Vehicle


The H-IIA Launch Vehicle is a high-performance launcher consisting of a First stage, Second stage, fairing, and one or two pairs of Solid Rocket Boosters (SRB-As). The propulsion system runs on liquid hydrogen and liquid oxygen. Two models are currently available, the standard type H2A202 with two SRB-As and the H2A204 type with four SRB-As attached.
The First stage of the H-IIA Launch Vehicle consists of a high-performance LE-7A engine, an engine section, a propulsion system tank charged with liquid hydrogen and liquid oxygen, a center section connecting the tanks, and an interstage section mating the First and Second stages.
The Second stage consists of a highly reliable LE-5B engine, a propulsion system tank charged with liquid hydrogen and liquid oxygen, on-board electronic devices, etc. As a key feature for launch mission support, the LE-5B engine can be ignited up to three times.


H-IIA Upgrade -- KOHDO-KA


The H-IIA upgrade project focuses on upper stage modifications to provide better services for customers. The coasting duration of the H-IIA upper stage will be enhanced from one hour to five hours by improving cross-cutting cryogenic propulsion technologies. This will enable the H-IIA launch vehicle to inject a spacecraft closer to geostationary orbit (GSO) than previous standard transfer orbit which will offer the benefits of extending the fuel life of launched satellites while also extending limited launch windows for planetary exploration missions.


Tanegashima Space Center

The Tanegashima Space Center (TNSC), established in 1969, is the largest rocket-launch complex in Japan with a total area of about 9,700,000 square meters. Located in the south of Kagoshima Prefecture, along the southeast coast of Tanegashima, it is known as the most beautiful rocket-launch complex in the world.
On-site facilities include the Yoshinobu Launch Complex, a launch site for large-size rockets, Spacecraft Test and Assembly Buildings, and the Spacecraft and Fairing Assembly Building. Using those facilities, a series of operations are performed from assembling launch vehicles, maintenance, inspections, final checks of satellites, loading satellites onto launch vehicles, launches, and tracking launch vehicles after liftoff. The TNSC plays a pivotal role for satellite launches among Japan’s space activities.
