ISRO Lauch fleet are:
1. SLV-3 (Satellite Launch Vehicle-3) – India’s first experimental satellite launch vehicle.
2. ASLV (Augmented Satellite Launch Vehicle)
3. PLSV (Polar Satellite Launch Vehicle) was first operational launch vehicle of ISRO.

ISRO SATELLITES: ✹Aryabhatta was First Indian Experimental Satellite launched on 19th April 1975.
✹First Earth Observation Satellite was BHASKARA-I launched on 7th June 1979.
✹First Geo-stationary Satellite was INSAT-IA launched on 10th April 1982.
✹Chandrayaan-1 was India’s first lunar probe. It was launched by ISRO on 22 October 2008.
✹IRNSS is an autonomous regional satellite navigation system that is being set up by India, that will be used to provide accurate real-time positioning and timing services over India and the region extending to 1,500 kilometres (930 mi) around India.
✹ Navigation with Indian Constellation (NAVIC) system will consist of a constellation of 3 satellites in Geostationary orbit (GEO), 4 satellites in Geosynchronous orbit (GSO), approximately 36,000 kilometres (22,000 mi) altitude above earth surface, and two satellites on the ground as stand-by, in addition to ground stations. The Indian government approved the project in May 2006.
✹ Indian Space Research Organisation (ISRO) has scripted history on 15th February 2016 as ISRO launched a record 104 satellites in one go on board a single rocket PSLV from the Satish Dhawan Space Centre in Sriharikota. 101 satellites were from international clients. Of these- 96 belong to USA, 5 from International customers of ISRO – Israel, Kazakhstan, Netherlands, Switzerland, United Arab Emirates, respectively. Two other Indian nano satellites INS-1A and INS-1B were also placed in orbit. India now surpasses the record of Russian Space Agency which had earlier launched 37 satellites in one go.
✹INS-1C was launched on 10 January 2018. INS-1C, the third satellite in the Indian Nanosatellite series, will be carrying a Miniature Multispectral Technology Demonstration (MMX-TD) Payload from Space Applications Centre (SAC).
