GSLV

GSLVGeosynchronous Satellite Launch Vehicle abbreviated as GSLV, is an expendable launch system operated by the Indian Space Research Organisation (ISRO).

静止衛星打ち上げ機 (GSLV) は、インド宇宙研究機関 (ISRO) が運用する使い捨て打ち上げシステム。

Geosynchronous Satellite Launch Vehicle Mark II (GSLV Mk II) is the largest launch vehicle developed by India, which is currently in operation. This fourth generation launch vehicle is a three stage vehicle with four liquid strap-ons. The indigenously developed cryogenic Upper Stage (CUS), which is flight proven, forms the third stage of GSLV Mk II. From January 2014, the vehicle has achieved four consecutive successes.

静止衛星打ち上げ機マーク II (GSLV Mk II) は、現在運用中のものとしてインドが開発した最大の打ち上げ機。第 4 世代にあたる 3 段式で、液体燃料の補助ブースター 4 本を備える。飛行実証済みの国産極低温上段 (CUS) が第 3 段を構成する。2014 年 1 月以降、4 回連続で成功している。

GSLV Mk. II

The Launch Vehicle Mark-3 (LVM-3), previously called Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III), is a three-stage medium-lift launch vehicle developed by the Indian Space Research Organisation (ISRO). It is designed to launch satellites into geostationary orbit, and is intended as a launch vehicle for crewed missions under the Indian Human Spaceflight Programme.

AST SpaceMobile’s Block 2 BlueBird satellites are designed to deliver up to 10 times the bandwidth capacity of the BlueBird Block 1 satellites, required to achieve 24/7 continuous cellular broadband service coverage in the United States, with beams designed to support a capacity of up to 40 MHz, enabling peak data transmission speeds up to 120 Mbps, supporting voice, full data and video applications. The Block 2 BlueBirds, featuring as large as 2400 square foot communications arrays, will be the largest satellites ever commercially deployed in Low Earth orbit once launched.

This launch will feature a single satellite.
