The SSLV-D1 was the first mission of the Small Satellite Launch Vehicle (SSLV). Due to a sensor fault during separation of second stage and subsequent initiation of Open Loop Guidance by onboard computer to salvage the mission, the upper stage did not fire for planned duration and payloads were ultimately injected into a decaying orbit not achieving the objectives of mission.
ISRO developed a small satellite launch vehicle (SSLV) to cater the launch of up to 500 kg satellites to Low Earth Orbits on ‘launch-on-demand’ basis.
SSLV-D1 mission launched EOS 02, a 135 kg satellite, with a planned Low Earth orbit of about 350 km altitude, at an inclination of about 37 degrees. EOS-02 was an Earth observation satellite designed and realised by ISRO. This microsat-type satellite offered advanced optical remote sensing operating in infrared band with high spatial resolution. The bus configuration was derived from IMS-1 bus.
The mission also carried the AzaadiSAT satellite. AzaadiSAT was a 8U Cubesat weighing around 8 kg. It carried 75 different payloads each weighing around 50 grams and conducting femto-experiments. Girl students from rural regions across the country were provided guidance to build these payloads. The payloads were integrated by the student team of “Space Kidz India”. The payloads included a UHF-VHF Transponder working in ham radio frequency to enable voice and data transmission for amateur radio operators, a solid state PIN diode-based Radiation counter to measure the ionising radiation in its orbit, a long-range transponder and a selfie camera. The ground system developed by ‘Space Kidz India’ was to be utilised for receiving the data from this satellite. [3]
SSLV launched on its maiden flight at 03:48 UTC / 09:18 IST on 7 August 2022, [1] [4] from the First Launch Pad, but failed to reach the intended orbit. [5] Due to an anomaly detected with accelerometers after second stage separation the stage as well as the two satellite payloads were injected into an unstable elliptical orbit measuring 356km × 76km and subsequently destroyed upon reentry. According to the ISRO, the mission software failed to identify and correct a sensor fault and switched to Open Loop Guidance to salvage the mission. [6] [7] This led to the VTM stage firing only briefly (0.1s) and payloads were injected to a very low perigee. [8]
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).
The Indian National Satellite System or INSAT, is a series of multipurpose geostationary satellites launched by ISRO to satisfy telecommunications, broadcasting, meteorology, and search and rescue operations. Commissioned in 1983, INSAT is the largest domestic communication system in the Indo-Pacific Region. It is a joint venture of the Department of Space, Department of Telecommunications, India Meteorological Department, All India Radio and Doordarshan. The overall coordination and management of INSAT system rests with the Secretary-level INSAT Coordination Committee.
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.
Rohini is a series of satellites launched by the Indian Space Research Organisation (ISRO). The Rohini series consisted of four satellites, each of which was launched by the Satellite Launch Vehicle (SLV) and three of which made it successfully to orbit. The series were mostly experimental satellites, with the first launch being in 1979. There was an earlier series of ISRO sounding rockets with the same name, first launched 1967.
Aditya-L1 (/aːd̪it̪jə/) is a coronagraphy spacecraft for studying the solar atmosphere, designed and developed by the Indian Space Research Organisation (ISRO) and various other Indian research institutes. It is orbiting at about 1.5 million km from Earth in a halo orbit around the Lagrange point 1 (L1) between the Earth and the Sun, where it will study the solar atmosphere, solar magnetic storms, and their impact on the environment around the Earth.
GSAT-10 is an Indian communication satellite which was launched by Ariane-5ECA carrier rocket in September 2012. It has 12 KU Band, 12 C Band and 6 lower extended c band transponders, and included a navigation payload to augment GAGAN capacity. Following its launch and on-orbit testing, it was placed in Geosynchronous orbit at 83.0° East, from where it will provide communication services in India.
EOS-04 or Earth Observation Satellite - 04 is an Indian Space Research Organisation Radar Imaging Satellite designed to provide high-quality images under all weather conditions for applications such as Agriculture, Forestry & Plantations, Soil Moisture & Hydrology and Flood mapping. It is a follow on to RISAT-1 satellite with similar configuration. The satellite is developed by the ISRO and it is the sixth in a series of RISAT satellites.
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.
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.
The PSLV-C44 was the 46th mission of the Indian Polar Satellite Launch Vehicle (PSLV) program. It was the first flight of PSLV-DL, having 2 strap-on boosters and placed a primary payload Microsat-R and a secondary payload of Kalamsat V2 in Sun-synchronous orbits.
The PSLV-C53 is the 55th mission of the Polar Satellite Launch Vehicle (PSLV) and 15th mission using PSLV-Core Alone variant. PSLV-C53 is the second dedicated commercial mission of NSIL.
EOS-02 was an Indian Earth observation microsatellite developed by the Indian Space Research Organisation as a test payload on the maiden launch of the Small Satellite Launch Vehicle (SSLV). EOS-02 was based on Microsat-TD. The objective behind EOS-02 was to realize and fly an experimental imaging satellite with short turnaround time to showcase launch on demand capability.
The PSLV-C54 was the 56th mission of the Indian Space Research Organisation's Polar Satellite Launch Vehicle (PSLV). It was launched on 26 November 2022 with the Oceansat-3 satellite and Thybolt nanosatellites of Dhruva Space from Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh, India.
AzaadiSAT was an Indian Earth observation 8U Cubesat weighing around 8 kg developed by the Space Kidz India as a test payload on the maiden launch of the Small Satellite Launch Vehicle (SSLV). It was hitching a ride with EOS-02, the primary satellite of the mission. The launch on 7 August 2022 was a failure in the rocket leading to imminent return to atmosphere for the rocket and the satellites it carried, destroying them all.
The SSLV-D2 was the second mission of the Small Satellite Launch Vehicle (SSLV). The vehicle carried three payloads: EOS–07, Antaris US Firm named as Janus-01 and AzaadiSAT-2 by SpaceKidz India.
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 PSLV fourth stage it is converted into 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.
EOS–07 or Microsat-2B is an Earth observation satellite developed by the Indian Space Research Organisation (ISRO) and launched during the SSLV-D2 mission, the first successful mission of the SSLV rocket. It's a minisatellite designed to accommodate new technology payloads in a quick turn-around time.
