EOS-07 was a 156 kg ISRO technology satellite launched on SSLV-D2, the second flight of the Small Satellite Launch Vehicle, in February 2023. It tested new instruments, including a millimetre-wave humidity sounder.
Re-entered Earth's atmosphere on 29 December 2024, according to the public satellite catalogue.
ISRO designed, built and realised EOS-07 as the main satellite of SSLV-D2. Its new experiments included a millimetre-wave humidity sounder and a spectrum monitoring payload.
Gunter's Space Page lists it as Microsat-2B, based on the earlier Microsat-TD. Its goals were to test new instruments on a small satellite bus and to show that such a satellite can be built quickly.
SSLV-D2 lifted off from the first launch pad at Sriharikota at 09:18 IST on 10 February 2023. In a flight of about 15 minutes it was to place EOS-07, Janus-1 and AzaadiSAT-2 in a 450 km circular orbit, and ISRO declared the mission accomplished.
SSLV is a 34 m rocket with three solid stages and a velocity terminal module. It is built to carry satellites of up to 500 kg to low Earth orbit at short notice. The first flight, SSLV-D1, failed to reach orbit in August 2022, so SSLV-D2 was the rocket's first success.
EOS-07 re-entered Earth's atmosphere on 29 December 2024, according to the public satellite catalogue.
