PRISMA HPGP first thruster firing

First In-space Green Propulsion Firing of ECAPS HPGP System! Between 03:26:42 and 03:37:09(UTC) the first in-space firing sequence was performed by firing a pulse train of 40 pulses with 100 ms firing duration at a duty cycle of 1%. The firing and it's effect on the orbit is shown in this video. The firing is performed after the Spacecraft is rotated to align the thruster with the anti-velocity direction. As the absolute change of the orbit is small the effect on the orbit is demonstrated adding a simulated version of the satellite "PRISMA Mango Simulated". This simulated satellite is initiated with the GPS Navigation position and velocity one hour before the thrust and is following a path without any thrust, representing the trajectory if there would not have been any thrust at all. PRISMA Mango's position and attitude is based on the real in-orbit GPS navigation and attitude estimation. As can be seen after the thrust PRISMA Mango is increasing its velocity and is reaching a higher altitude, this higher orbit is orbiting the earth at a slower pace and we can see the effect when the simulated satellite is quickly disappearing ahead of us. The speed of the video is 100 times real time.
