Ovzon 3 - preparing for launch

TOP SPEED DURING LAUNCH           36,000km/h / 22,370 mi/h
ALTITUDE ABOVE EARTH EQUATOR   35,786km / 22,236 miles
WIDTH OF DEPLOYED SATELLITE           27m / 89ft
WEIGHT OF SATELLITE                   1,800kg / 3,968lb

Ready for lift-off!

We are getting closer to the historic launch of our first satellite – Ovzon 3.

Ovzon 3 is the first privately funded and developed Swedish geostationary satellite ever to be launched. It’s also the most powerful GEO satellite ever to be put into orbit covering 1/3 of the earth via its steerable spot beams. The satellite carries Ovzon’s patented solution with high power steerable beams and unique software defined capabilities.

Launched via a Falcon 9 rocket from Cape Canaveral, Florida, Ovzon 3 will reach a geostationary transfer orbit. Once released from the rocket’s 3rd stage at an apogee of 36,000 km, Ovzon 3 will utilize its internal electric propulsion system. Over a span of 3-4 months, it will gradually transition from the transfer orbit to its designated geostationary orbit position, or ‘parking lot,’ at 59.7 degrees east.

The launch of Ovzon 3 will take place at SpaceX Air Force Station in Cape Canaveral, Florida, USA. The exact launch date has not been finalized yet, but the time window allocated to us is during December. We will provide a more specific date as we receive additional details from SpaceX within the upcoming weeks.

Launched via a Falcon 9 rocket [...] Once released from the rocket’s 3rd stage at an apogee of 36,000 km, Ovzon 3 will utilize its internal electric propulsion system. Over a span of 3-4 months

Hold up... 3rd stage?

Did they just neglect to update that line when they changed launch vehicles, or is there actually a kick stage?

It's the sats own electric propulsion

Because the Maxar Technologies-built satellite will rely on electric propulsion, it will take several months to climb to its slot at 59.7 degrees East after reaching geostationary transfer orbit aboard a Falcon 9 rocket.

When Ovzon 3 was originally manifested for Ariane 5, a brochure listed the targeted GTO apogee as 71,000 kilometers (supersynchronous transfer orbit). Why was the apogee lowered to normal GTO altitude (35,786 kilometers)?

Probably because Falcon 9 doesn't have the extra performance available for super-GTO.

I think F9 could send this to the moon.

this likely will be the spicyest RTLS in all likelihood! also means that it may not be going to some crazy supersynch gto!

Not that it matters; but I bet on the Orbiter 2016 simulator, even with Stage 1 boosting back to LZ-1, I can get Ovzon 3 to an apogee of 71,000 kilometers as originally intended back then.

This is crazy!

They are really getting comfortable squeezing the margins on the F9.
Wildly optimistic prediction, Superheavy recovery on IFT-4 or IFT-5

This is part of what they have to do if they want to get to 144 next year.

Delayed by 24 hours, which was to be expected with the recent 24-hour delays to recent Starlink Group 6 missions:

NextSpaceflight has 20:46 UTC for the launch. well 1 min., maybe rounded differently.
But I fear that further postponement will occur, depending on when Starlink 6-34 can take place.
The launch date of USSF-52 could also have an impact. The landing zone must be clear after that.

Map from the NGA notice. The ASDS location 477km downrange is just a SWAG.

EDIT: the area may be for a failed boostback burn only.
