The PSLV-C45 [1] is the 47th mission of the Indian Polar Satellite Launch Vehicle (PSLV) program. The Polar Satellite Launch Vehicle (PSLV)-C45 was launched on 1 April 2019 with a payload of 29 satellites, including one for electronic intelligence, along with 28 customer satellites from other countries.
The PSLV-C45 was launched from the second launch pad of the Satish Dhawan Space Centre in Sriharikota, Andhra pradesh,India. The PSLV C45 rocket carried primary payloads like EMISAT and secondary payloads like M6P, BlueWalker 1, four Lemur-2 out of a total of thirty satellites. [2] EMISAT [3] is developed by DRDO. [4] The EMISAT satellite is based on the IMS-2 bus inherited from SARAL. The nature of the payload has not been officially confirmed.
It was the first flight of PSLV-QL, [1] having 4 strap-on boosters and placed a primary payload EMISAT and a secondary payload of multiple cubesats, for example 4 Lemur-2 satellites and the M6P satellite, in Sun-synchronous orbits.
The specialty of this mission is that for the first time PSLV will launch satellites in Three different orbits. [5] [6] [7] Another distinguished feature of the project is for the first time, PSLV with four strap-on [2] configuration has been identified for this mission. Until now, PSLV has been in either two or six strap-on configuration or without any strap-ons. it is also the first PSLV to have fourth stage (PS4) that uses solar panels to support payloads hosted on it, seen as a precursor to the PSLV Orbital Experiment Module. [8]
Mission starts with the injection of the satellite EMISAT into orbit at 780 km, then it will inject 29 satellites into orbit at 504 km and later the fourth stage will move to 485 km orbit to carry out scientific experiments.
The launch was originally scheduled for 21 March 2019, but was delayed to 1 April "to ensure system readiness for a perfect launch". [9]
The PSLV C45 rocket had four stages; each one was self-contained, with its own propulsion system, thereby capable of functioning independently. [2] The first and third stages used composite solid propellants, while the second stage used earth-storable liquid propellant and fourth one fitted with Solar Panels. [2]
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, only commercially available from Russia. PSLV can also launch small size satellites into Geostationary Transfer Orbit (GTO).
Geosynchronous Satellite Launch Vehicle (GSLV) is a class of expendable launch systems operated by the Indian Space Research Organisation (ISRO). GSLV has been used in fifteen launches since 2001.
Satish Dhawan Space Centre – SDSC, is the primary spaceport of the Indian Space Research Organisation (ISRO), located in Sriharikota, Andhra Pradesh.
The Launch Vehicle Mark-3 or LVM3 is a three-stage medium-lift launch vehicle developed by the Indian Space Research Organisation (ISRO). Primarily designed to launch communication satellites into geostationary orbit, it is also due to launch crewed missions under the Indian Human Spaceflight Programme. LVM3 has a higher payload capacity than its predecessor, GSLV.
PSLV-C34 was the 36th mission of the PSLV program and 14th mission of PSLV in XL configuration. The PSLV-C34 successfully carried and deployed 20 satellites in the Sun-synchronous orbit. With a launch mass of 320,000 kilograms (710,000 lb) and payload mass of 1,288 kilograms (2,840 lb), the C34 set a new record of deploying the maximum number of satellites by Indian Space Research Organisation in a single mission. The PSLV-C34 carried One Cartosat-2 satellite, SathyabamaSat, Swayam & 17 other satellites from United States, Canada, Germany & Indonesia.
PSLV-C35 was the successful mission of the Polar Satellite Launch Vehicle program which set eight satellites in space. It was launched on 26 September 2016 by Indian Space Research Organisation (ISRO) from the Satish Dhawan Space Centre at Sriharikota.
PSLV-C3 was the third operational launch and overall sixth mission of the PSLV program. This launch was also the forty-sixth launch by Indian Space Research Organisation since its first mission on 1 January 1962. The vehicle carried three satellites which were deployed in the Sun-synchronous Low Earth orbit. The vehicle carried Technology Experiment Satellite, BIRD and PROBA. This was India's and ISRO's second commercial spaceflight. PSLV-C3 was launched at 10:23 a.m. IST on 22 October 2001 from Satish Dhawan Space Centre.
PSLV-C6 was the sixth operational launch and overall ninth mission of the PSLV program. This launch was also the fifty-fourth launch by Indian Space Research Organisation since its first mission on 1 January 1962. The vehicle carried and injected India's two satellites; Cartosat-1 and HAMSAT into the Sun-synchronous orbit. PSLV-C6 was launched at 04:44 hours Coordinated Universal Time on 5 May 2005 from the second launch pad of the Satish Dhawan Space Centre.
PSLV-C37 was the 39th mission of the Indian Polar Satellite Launch Vehicle (PSLV) program and its 16th mission in the XL configuration undertaken by the Indian Space Research Organisation (ISRO). Launched on 15 February 2017 from the Satish Dhawan Space Centre at Sriharikota, Andhra Pradesh, the rocket successfully carried and deployed a record number of 104 satellites in Sun-synchronous orbits in a single mission, breaking the earlier record of launching 37 satellites by a Russian Dnepr rocket on 19 June 2014. This record was held until the launch of the Transporter-1 mission by SpaceX on 24 January 2021 which launched 143 satellites.
The Small Satellite Launch Vehicle (SSLV) is a small-lift launch vehicle developed by ISRO with payload capacity to deliver 500 kg (1,100 lb) to low Earth orbit or 300 kg (660 lb) to Sun-synchronous orbit for launching small satellites, with the capability to support multiple orbital drop-offs. SSLV is made keeping low cost, low turnaround time in mind with launch-on-demand flexibility under minimal infrastructure requirements.

PSLV Orbital Experiment Platform (POEM) also known as PSLV Stage 4 Orbital Platform (PS4-OP) is an orbital micro-gravity test bed based on spent fourth stage of PSLV. By adding modular subsystems for power generation, communication and stabilization like photovoltaic cells, Telemetry and Telecommand (TT&C) package, attitude control system, data storage etc to the PSLV fourth stage, it can function as a satellite bus. This augmented stage can then host payloads for up to six months while in orbit, making it useful for qualifying components, gaining space heritage and conduct experiments in micro-gravity conditions. Usually the fourth stage of PSLV is discarded after deployment of satellite and remains in orbit for a significant duration in a passive state as a piece of space debris.
