ThePSLV-C55was the 57th mission ofIndian Space Research Organisation'sPolar Satellite Launch Vehicle(PSLV) and the 16th flight of thePSLV-CAvariant.[1]
Launch
[edit]It was launched on Saturday, 22 April 2023 at 14:19 IST / 08:49 UTC fromSatish Dhawan Space Centre, Sriharikota,Andhra Pradesh, India.[2][3]This was a dedicated commercial mission throughNSILwithTeLEOS-2as primary satellite andLumelite-4as a co-passenger satellite weighing 741 kg and 16 kg respectively.[1]Both satellites belong to Singapore.[4]
Mission overview
[edit]Primary payload:TeLEOS-2
Secondary payload:Lumelite-4
This also marks the third time thatPS4is used after satellite separations as a platform for experiments. There are non-separable payloads mounted on MSA (multi-satellite adapter).[5]Payloads are powered on by a command after all satellites are separated. The orbital platform will remain in the same orbit achieved at the end of PS4 tank passivation after the primary mission. It has an expected life of 1 month.[1]
As a part of POEM-2 (PSLV Orbital Experimental Module), there are seven experimental non-separable payloads:[1][6]
- PiLOT (PSLV In orbitaL Obc and Thermals) OBC package fromIIST
- OBC package fromIIST
- ARIS-2 (Advanced Retarding Potential analyser for Ionospheric Studies) experiment fromIIST
- HET based ARKA200 Electric Propulsion System fromBellatrix Aerospace
- DSOD-3U and DSOD-6U deployer units along with DSOL-Transceiver in S- & X- bands fromDhruva Space
- Starberry Sense Payload fromIndian Institute of Astrophysics(IAP)
| Parameter | Orbit-1 |
|---|---|
| Semi-Major Axis (km) | 6964 |
| Alt (km) | 586 |
| Eccentricity | 0.0 |
| Inclination (deg.) | 10.00 |
| Launch Pad | FLP |
| Launch Azimuth (deg.) | 104 |
Propellant:[1]
- Stage 1:Composite Solid(HTBPbased)
- Stage 2:Earth Storable Liquid(UDMH+N2O4)
- Stage 3:Composite Solid(HTBPbased)
- Stage 4:Earth Storable Liquid(MMH+MON3)
The PSLV C55 rocket has four stages; each one was self-contained, with its ownpropulsion system,thereby capable of functioning independently. The first and third stages used composite solid propellants, while the second and fourth stage use earth-storable liquid propellant.
