EOS-04: EOS-04 is a repeat Satellite of RISAT-1 and is configured to ensure continuity of Synthetic Aperture Radar in C-Band providing Microwave data to the user community for operational services. The satellite has the capability to operate in day, night and all weather conditions with a Mission life of 5 years and provides imaging data for various applications related to Land, Water and environment which find useful inputs for Agriculture, Forestry and Water resource management.
Future Missions of PSLV that are slated for launch in 2021 includes PSLV-C51/Amazonia-1, PSLV/EOS-04, PSLV/EOS-06.
#EOS04 mission update Integration of #PSLVC52 has started at vehicle building assembly at SDSC SHAR as EOS 04 satellite arrived today at FLP.Information given by @GareebiKi
September is targeted The launch date will be finalised soon.
Any new news?
EOS-4 was to be originally launched in September, sources in Isro said, adding that the review committee had not cleared the satellite, which postponed the launch.

As many arterial roads in Nellore have to be closed due to the floods, Isro is not able to finalise its launches.Isro chairman K Sivan told TOI, "We have been working on three launches, including the small satellite launch vehicle (mini-PSLV) launch, before the year ends. But due to heavy rain and floods in Andhra, we have to reassess the situation... We can decide on the three launches only when the flood situation improves."

Looks like technical problems have continued to plague all three upcoming ISRO missions:Teething troubles with indigenous tech cause for delay in 2 Sat launches; humidity halts SSLV [dated Dec. 1] (bolds mine)QuoteTeething troubles with multiple indigenous modules on one satellite and domestic mirror fabrication on the other are major causes for delay in the launch of two Earth Observation Satellites (EOSs) Isro had in its pipeline, while increased humidity has put on hold a key process on the first small satellite launch vehicle (SSLV) mission.TOI had reported earlier that Isro was hoping to launch three Earth Observations Satellites (EOSs) — two of them (EOS-4 or Risat-1A and EOS-6 or Oceansat-3 using PSLV and the third, EOS-2 or Microsat as part of the first developmental flight of the Small Satellite Launch Vehicle (SSLV) — in the last quarter of 2021.A senior scientist from Isro headquarters told TOI that Risat-1A got into serious technical issues after more than 20 TR [transmit and receive] modules fabricated indigenously for the first time failed ground tests."...When so many modules fail ground tests, unless we understand the criticality of the problem, we cannot go ahead and launch. The satellite could have gone to waste if we went ahead and we had Rs 700 crore at stake. Also, with 5G coming, the frequency of the satellite had to be changed to prevent interference. These are the reasons for delay. Now the technical issues have been addressed and we will start preparations for the launch soon," the scientist said.TR modules refer to transmit and receive modules that help in telemetry and tracking of the satellites, and another scientist said that the Risat-1A has around 400 of these.

This will launch from the FLP (First Launch Platform)?Any news of an impending launch campaign?

According to an article in Telugu published January 3, PSLV C53 with Oceansat-3 should launch from First launch Pad on January 20 or in February if the satellite is delayed.
