PSLV

The Polar Satellite Launch Vehicle (PSLV) is an expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into sun-synchronous orbits, a service that was, until the advent of the PSLV in 1993, commercially available only from Russia. PSLV can also launch small size satellites into Geostationary Transfer Orbit (GTO).

極軌道衛星打ち上げ機 (PSLV) は、インド宇宙研究機関 (ISRO) が設計・運用する使い捨ての中型打ち上げ機。インドのリモートセンシング衛星 (IRS) を太陽同期軌道へ打ち上げられるよう開発された。このサービスは 1993 年に PSLV が登場するまでロシアからしか商業的に得られなかった。小型衛星を静止トランスファ軌道 (GTO) へ打ち上げることもできる。

PSLV-XL is the upgraded version of Polar Satellite Launch Vehicle in its standard configuration boosted by more powerful, stretched strap-on boosters with 12 tonne propellant load. Weighing 320t at lift-off, the vehicle uses larger strap-on motors (PSOM-XL or S12) to achieve higher payload capability. On 29 December 2005, ISRO successfully tested the improved version of strap-on booster for the PSLV. The first use of PSLV-XL was the launch of Chandrayaan-1 by PSLV C11. The payload capability for this variant is 1,800 kg to SSO.

PSLV-XL は標準構成の PSLV を、推進剤 12 t を積むより強力で延長された補助ブースターで強化した改良型。離昇時の重量は 320 t で、大型の補助モーター (PSOM-XL または S12) により高いペイロード能力を実現する。ISRO は 2005 年 12 月 29 日に改良型補助ブースターの試験に成功し、PSLV-XL の初使用は PSLV C11 によるチャンドラヤーン 1 号の打ち上げだった。この型の太陽同期軌道へのペイロード能力は 1,800 kg。

The PSLV-CA, CA meaning "Core Alone", model premiered on 23 April 2007. The CA model does not include the six strap-on boosters used by the PSLV standard variant. The fourth stage of the CA variant has 400 kg less propellant when compared to its standard version. It currently has capability to launch 1,100 kg to a 622 km Sun synchronous orbit.

PSLV-CA (CA は「コアのみ」の意) は 2007 年 4 月 23 日に初登場した型。標準型 PSLV の補助ブースター 6 本を持たず、第 4 段の推進剤は標準型より 400 kg 少ない。現在、高度 622 km の太陽同期軌道へ 1,100 kg を打ち上げる能力を持つ。

PSLV-DL variant has only two strapons boosters with 12 tonne propellant load on them. PSLV-C44 on 24 January 2019 was the first flight to use PSLV-DL variant of Polar Satellite Launch Vehicle.

PSLV-DL 型は推進剤 12 t を積む補助ブースターを 2 本だけ持つ。2019 年 1 月 24 日の PSLV-C44 が PSLV-DL 型の初飛行だった。

PSLV-QL variant has 4 strapons and all are ground-lit starpon variant with a combined propellant of 48 tonnes.
