I can be wrong on this but I think it successfully inserted into orbit.
ISRO graphs are
relative velocity:
According to this the SS3(stage 3) cut off at ~7.3km/s of
relative velocity.
But in reality you need ~7.69 km/s of
absolute velocity to sustain a circular(if ISRO is attempting a circular) orbit of ~356km.
But since ISRO's graphs are
relative velocity, they are not taking into account the speed gained by rotation of the Earth => which, at 0° inclination(or along the equator) is 460m/s.
However the satellite is inserted at an inclination of 37°, so by multiplying:
460 x cos(37) => 367.3m/s => 0.36km/s.
So the
absolute velocity of the satellite is 7.3km/s + 0.36km/s => 7.66km/s, which is only off by 30m/s to maintain a
circular orbit. If they don't go for a circular orbit, they can probably still maintain something like a 356 x 120km~ orbit, at that speed.
After SS3 separation, the VTM fired for about 0.1 seconds =>
Weight at that point: 143kg.
Thrust: 800N
Duration: 0.1 seconds
Force = Mass.Acceleration => 800 = 143.Acceleration
=> 5.5m/s^2 acceleration.
=> 5.5 * 0.1 => 0.5m/s gained, and then the VTM stopped firing.
So the final orbital speed is somewhere around 7.66-7.67km/s.. so we'll see what happens. If there is an orbit, we should see a statement from ISRO. Otherwise it already burned up somewhere around Australia at around 10:20am
