EOS-02 (formerly known as Microsat-2A) 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).{{Cite web|title=India's GISAT-1, Microsat 2-A, GSAT-12R, RISAT-2BR2 satellites ready for launch, says senior ISRO official|url=https://www.dnaindia.com/science/report-india-s-gisat-1-microsat-2-a-gsat-12r-risat-2br2-satellites-ready-for-launch-says-senior-isro-official-2843780|access-date=2022-02-14|website=DNA India|language=en}} 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.{{Cite web |date=2022-08-07 |title=India Completes Maiden SSLV Mission, ISRO Says Orbit Achieved Was 'Less Than Expected' |url=https://www.news18.com/news/india/india-completes-maiden-sslv-mission-isro-says-orbit-achieved-was-less-than-expected-5704285.html |access-date=2022-08-07 |website=News18 |language=en}}
It was intended to be used for cartographic applications at a cadastral level, urban and rural management, coastal land use and regulation, utilities mapping, development and various other GIS applications. The satellite carried two payloads: a mid-wavelength and a long-wavelength infared camera with a 6m resolution.{{Cite web|title=Annual Report 2019-20 (English)|url=https://www.isro.gov.in/sites/default/files/flipping_book/annual_report_2019-20_english/index.html|access-date=2022-02-15|website=www.isro.gov.in|archive-date=2020-04-06|archive-url=https://web.archive.org/web/20200406131804/https://www.isro.gov.in/sites/default/files/flipping_book/annual_report_2019-20_english/index.html|url-status=dead}}

As a result, both satellites onboard (EOS-02 and AzaadiSAT) were destroyed during reentry.{{Cite tweet|number=1556208112138215424|user=isro|title=SSLV-D1/EOS-02 Mission update: SSLV-D1 placed the satellites into 356 km x 76 km elliptical orbit instead of 356 km circular orbit. Satellites are no longer usable. Issue is reasonably identified. Failure of a logic to identify a sensor failure and go for a salvage action caused the deviation. A committee would analyse and recommend. With the implementation of the recommendations, ISRO will come back soon with SSLV-D2. A detailed statement by Chairman, ISRO will be uploaded soon.|author=Indian Space Research Organization|date=2022-08-07}}
