Payload: IndoStar II/ ProtoStar II communication satellite 601 HP

Spacecraft: IndoStar II/ ProtoStar II

Manufacturer: Boeing Satellite Systems

The IndoStar II/ProtoStar II satellite is the second satellite in ProtoStar’s evolving constellation. The satellite will replace the existing Chakarawarta 1 and will bring high-power S-band and Ku-band capacity over Indonesia, India, the Philippines and Taiwan. The satellite’s S-band transponders will be supporting the Direct-to-Home (DTH) television services of Indovision, Indonesia’s largest DTH operator. The satellite will also be providing large block capacity to support new high definition television services as well as other multi-media, broadband services across the region.

Protostar II Ascent Profile

Indostar II / Protostar II satellite will be launched according to the proven ascent profile using a standard ascent trajectory and drop zones of the launch vehicle jettisonable parts.

Proton-M Powered Flight Chart

Breeze-M Powered Flight

Immediately after the separation of the third stage booster, the Breeze-M stability engines start, damping the angular velocities of the third stage separation and then providing ascent unit orientation and stability during coast flight along a suborbital trajectory to await the first burn.

The upper stage follows a five-burn injection profile.

The first burn occurs 94 sec after the separation from the rocket, forming a support orbit.

The second burn transfers the ascent unit to an intermediate orbit. The third and fourth burns form a transfer orbit with an apogee close to that of the target orbit. The additional propellant unit is jettisoned during the gap between the third and the fourth burns. The target geotransfer orbit is formed by the fifth burn performed by in the transfer orbit apogee.

Once in the target orbit, the ascent unit is stabilized for Indostar II /Protostar II separation, following which the satellite is released.

After the craft separation GTO parameters are measured, and the upper stage is withdrawn to drift in a safe mode (pressure in all the containers is dropped).

The Breeze-M powered flight lasts 33,300 seconds (9 hours 15 minutes).

After a nominal plane change burn, we have a clean separation of the Protostar II satellite from the upper stage over the Indian Ocean! The upper stage's deorbiting is pending.

The Proton has lit the ProtoStar up! :speakcool:

Thank you, although the most of the credit goes to Khrunichev and the ILS for their good public launch coverages.
