Re: Soyuz launch vehicle:
From
Russian space program in 2018:
The launch vehicle for the mission arrived at Baikonur around the middle of October 2018.
And:
Google translation:
"Two Soyuz 2.1 missiles were delivered to Baikonur, a source at the cosmodrome told RIA Novosti. These are the first carriers who arrived here after a recent accident.
A train arrived from Samara, which delivered two Soyuz launch vehicles to the cosmodrome: Soyuz-2-1b, intended for the Egyptian satellite EgyptSat-A scheduled for December 27, and Soyuz-2-1a, which on February 8, 2019, the Progress MS-11 cargo ship should be put into orbit, the agency’s source said.
According to him, both launches will be held from the 31st platform."

Is EgyptSat-A expected to launch into a 51.6 deg. inclination orbit, as its predecessor did?
If so, why? Why not launch into a SSO more suited for remote-sensing, on a Soyuz, from Plesetsk or Vostochniy? (My understanding, perhaps incomplete, is that Kazakhstan no longer allows SSO azimuth launches from Baikonur.)
Any idea of the launch window?

According to the article above EgyptSat-A is going to SSO this time (hence the use of Soyuz-2.1b/Fregat, using one originally allocated for GLONASS launches according to the article). Kazakhstan actually still allows SSO launches from Baikonur as long as Russia pay the clean up bill.

In contrast to Egyptsat-2 this time the Fregat is used.
So Egyptsat-A reaches its orbit immediately and can be put into operation faster, right?
A Volga could do that too, along with a Soyuz 2.1a or 2.1v.
But is not available? So a Soyuz 2.1b / Fregat-M is used because it's available? crazy
A Soyuz 2 with Volga could also launch from Plesetzk in the SSO.
A Soyuz 2 / Fregat SSO launch from Plesetzk did not exist yet.
I suspect that has something to do with the fall zone of the third stage.

The firm’s previous attempt to send a satellite into orbit in November 2017 was unsuccessful because it was riding on a Russian Soyuz-2.1b rocket that failed.

Launched satellite Egyptsat-A
Today, February 21, 2019, from the Baikonur cosmodrome at 19:47 Moscow time, the Soyuz-2 space launch vehicle was launched with the Egyptsat-A satellite, created in the interests of the Government of the Arab Republic of Egypt.

The Egyptsat-A satellite, launched on February 21 from the Baikonur cosmodrome at 19:47 Moscow time, was successfully launched into a working orbit and taken over by Russian specialists at the Egyptian Mission Control Center. All parameters of the onboard systems of the spacecraft are normal
The launch of the flight test program of the satellite, after which the spacecraft will be transferred to the control of the Egyptian side.
Satellite Egyptsat-A was created in the interests of the Government of the Arab Republic of Egypt. The spacecraft is designed to capture the earth's surface with high spatial resolution.

Destiny described here: http://russianspaceweb.com/egyptsat-a.html
Sat short name is ES-2A. Sat is slightly heavier than previous ES-2
So, two Fregat burns? First to raise transfer orbit perigee (even for nominal case, and this time extended...
would be nice to know the originally planned Blok-I perigee, can probably model it given the Arctic impact point)
and second to circularize. Plus a third burn for Fregat deorbit.
Also, at one point it was suggested there would be secondary payloads, but it looks like that's definitely not the case?

MOSCOW, Feb 23 - RIA News. The cause of the emergency situation when the Egyptian satellite Egyptsat-A was launched, which led to the premature shutdown of the third stage engine of the Soyuz-2.1b launch vehicle, was the human factor, due to incorrectly tuned sensors in the rocket, the fuel was prematurely out of power, the source told the rocket - space industry.
"It was a human factor. Experts mistakenly set up the sensors before launching at the cosmodrome. As a result, an oxidizer ended prematurely in flight at the third stage of the rocket, and the engine shut down before the scheduled time," said the agency interlocutor.

Block I was not intended to reach orbit. It flew as scheduled on suborbital trajectory. First Fregat burn was to insert in orbit, and second burn was to raise perigee.

So, two Fregat burns? First to raise transfer orbit perigee (even for nominal case, and this time extended...

Yes, I realize that of coruse. From an orbital mechanics point of view though, suborbital objects still have an orbital perigee value even if it never reaching it.
To match the intended impact zone between Svalbard and Greenland, an orbit of about
-1300 x 200 km seems to fit. A 30 m/s underspeed would give the reported 60 km shortfall in perigee to -1360 x 200 km, suggesting an impact of stage 3 only mildly downrange from the target, on the NE coast of Greenland
around 80N.

MOSCOW, February 25 - RIA News. The premature shutdown of the third-stage Soyuz-2.1b rocket when the Egyptian satellite EgyptSat-A was launched on February 21 was due to the fact that an oxidizer was not added to the Baikonur cosmodrome, the source in the rocket and space industry told Monday.
“Before starting, the oxidizer filling level sensors were set up incorrectly. As a result, less oxidizer was loaded into the third-stage tank of the Soyuz-2.1b rocket. Accordingly, the oxidizer ended prematurely and the engine turned off before the allotted time ...”

So TsENKI is at fault then.

Since Block I's acceleration at the end of the burn is about 3g, 30 m/s shortfall would imply shutting down about 1 second earlier than it should've.

Launcher serial numbers found so far:
February 21 (16:47) - EgyptSat-A - Soyuz-2.1b/Fregat-M (76031216/??)
Fregat-M serial number anyone??

Wow!
That's... stunning!! What a wonderful use of an HD camera? Is there info on this part of the payload?
Those ion engines starting up and running -- I'd never seen anything like that for real operation in space! It's also great to see the flexing of the bulkhead at, I assume, Fregat cutoff. Excellent views, thank you for the link!

Sen streams 4K video from space
19.05.19
Sen announces that it has successfully demonstrated its 4K video streaming platform in orbit, hosted aboard a satellite manufactured by S. P. Korolev Rocket and Space Public Corporation Energia (“RSC Energia”).
Sen’s system is the world’s first 4K video streaming platform from a satellite.
The platform, which comprises six video cameras and the Sen Video Unit containing a computer system to operate the video cameras and process the video data, was designed, developed and built by Sen.
The platform has demonstrated successfully its capability of recording six 4K video streams simultaneously in order to provide information about the spacecraft. Sen’s video cameras can stream real-time 4K video from the spacecraft, and two of the cameras are robotically steerable to capture a range of views of the spacecraft and also to film wide angle imagery of Earth.
Charles Black, Founder & CEO of Sen, said “We’ve spent years planning and developing the technology to stream real-time 4K video from space, so it's a great achievement to have our first successful mission. The mission is our tech demonstration of the world’s first 4K video from a satellite and the world’s most powerful video platform ever to operate in space. This mission validates our core technology which will be deployed in future on both hosted cameras and our own satellites as Sen develops its business of streaming videos from space for the benefit of humanity.”
Employees of RSC Energia appreciate Sen for providing the 4K video system for the satellite, including moving cameras, and are happy with the opportunity to be the first to implement Sen’s innovative platform to acquire additional information about the health and operations of the satellite. RSC Energia is planning to use Sen’s video streaming platform on future spacecraft that are being developed.
About Sen: https://sen.com
Sen was founded in 2014 by Charles Black with a vision to democratize space with unique video perspectives of our ever-changing world and our future in space, to inform, educate, inspire and benefit all humanity. Sen’s mission is to stream real-time videos to billions of people. Sen will capture its unique video content using both hosted video cameras and its own constellations of small satellites. Pronounced as a word rather than individual letters, Sen is an acronym for ‘space exploration network’. Sen is based in London, United Kingdom.
