ISRO Launch Vehicle Mark 3 (LVM3) is a three stage launch vehicle:
- First stage – S200 Boosters
- Second stage – L110
- Third stage – C25
Where do each of these stages end up after a launch?
Here is the map I prepared from NOTAM issued to define drop zones for spent stages of GSLV Mk. III (now known as LVM3) D1 mission that launched GSAT-19 satellite into GTO orbit.
And here are the flight events.
The hazard zones from Zone 1 to 4 are for range clearance, S200 splashdown, Payload fairing or 'heatshield' splashdown and L110 core stage splashdown.
The upper-stage C25 goes into orbit along payload and is not de-orbited post-mission and merely passivized.
For recent LVM3-M2 launch with OneWeb's batch 14 satellites, it was a southward flight path. You can see the resulting dogleg in following map and S200 drop zone is merged with payload fairing drop zone (DZ2)
That depends on where exactly you're going with it. Let me explain.
If the rocket is only going to LEO, the boosters end up being expended, namely by just dropping them into the sea and then they break apart on impact. The core stage flies further up and then once it runs out of fuel, it separates from the Launch Vehicle and burns up on re-entry. After that, the second core stage fires and gets to LEO, then is safely deorbited. If you are going to GTO, pretty much the same thing happens except the core stage flies further.
