Atlas V 551 - AFSPC-11 - April 14, 2018
« on: 01/20/2018 10:35 am »
Seeing that launch is coming up and no topic exists yet for this one, here's one.  ;)

So does anyone have ideas of what AFSPC-11 is? I was initially surprised by the use of the -551, but according to Gunther the EAGLE spacecraft will be on board and to be flown directly to geostationary orbit. That spacecraft "...can support payloads up to a weight of 1086 kg for a mission of at least one year." so it could be weighting up to 2 tonnes, which is already about half of the maximum capability of the -551 (just shy of 4 tonnes to GEO).

So another "satellite surveillance/inspector" thingy? What other kinds of satellites would the AFSPC potentially operate?

With the Atlas V-551 the MUOS satellites were placed in the GEO orbit, which had a mass of ~ 6740 kg!

The MUOS satellites were not directly put into GEO, but into a ~ 3800 km by 35700 km transfer orbit with 19° inclination

You are right, not directly in GEO.

It has a humorous logo.  Took me a while to get it.  Younger people might not right away.  (Sorry, can't post it yet)

I would suggest "This is Spinal Tap" for those wishing to do some background research...

Note that the launch time is given as 6-10 pm Eastern (22:00-02:00 UTC) by SFN. ;)

Payloads flying on AFSPC-11:
Primary Payload AFSPC-11 is completely classified at this time.
Secondary Rideshare is EAGLE (carrying payloads: HTI-SpX, MYCROFT (Classified), CEASE-III-RR, ISAL, ARMOR).

Public information:
http://space.skyrocket.de/doc_sdat/eagle.htm
http://space.skyrocket.de/doc_sdat/mycroft.htm

ISAL is satellite surveillance/inspector" thingy that you are looking for. ISAL (Inverse Synthetic Aperture Ladar) to provide high resolution images which are not limited in resolution by the diffraction limit of the telescope collecting the imaging data. This makes it an ideal method for imaging Geosynchronous Earth Orbit (GEO) space objects which happens to be ISAL's primary mission.

Spacecraft/Payload Acronyms:
EAGLE (ESPA Augmented Geostationary Laboratory Experiment) (Built using OATK ESPAStar Platform
HTI-SpX (Hypertemporal Imaging Space Experiment)
MYCROFT (Acronym is classified. Built using OATK ESPASat Bus.)
CEASE-III-RR (Compact Environmental Anomaly Sensor III Risk Reduction)
ISAL (Inverse Synthetic Aperture Ladar)
ARMOR (AFRL - 1201 Resilient Spacecraft Bus Development Experiment)

Thanks. Is this the launch that at one stage people thought initially was an X-37B flight?

I think so, but I dont remember that far back right now.

Inverse synthetic aperture LADAR for geosynchronous space objects – signal-to-noise analysis
Pellizzari, Matson, and Gudimetla
September 2011
http://www.dtic.mil/docs/citations/ADA550680
http://www.dtic.mil/dtic/tr/fulltext/u2/a550680.pdf

Inverse synthetic aperture LADAR (ISAL) provides high resolution images which are not limited in resolution by
the diffraction limit of the telescope collecting the imaging data. This makes it an ideal method for imaging
Geosynchronous Earth Orbit (GEO) space objects. Although LADAR is a well researched topic, little has been
published on the suitability of ISAL for imaging GEO space objects and the associated SNR models. This paper
derives an expression for the return signal detected by a coherent ISAL system. Using tomographic techniques
common to synthetic aperture radar (SAR), a model is developed for the signal-to-noise ratio of the reconstructed
image. Noise sources considered include photon noise and laser speckle noise.

ISAL is one of the experiments that will form the basis for missions such as for example GSSAP Follow On, which, is soon to enter the formulation stage by USAF and other government agency partners, might use technology derived from ISAL and other flown and upcoming STP experiments. ISAL also has  a air based hyperspectral equivalent that is used by the Civil Air Patrol (USAF AUX) and other agencies called Airborne Real-time Cueing Hyperspectral Enhanced Reconnaissance (ARCHER) that is currently in use for Search and Rescue and other classified sorties.

Any signs of that logo around? I saw that ULA's website already have the mission poster for this launch on their website.

Completed the President’s Mission Readiness Review for AFSPC11. Clean bird. Everything about this one is interesting. Too bad I can’t tell you anything about it...

Probably sourced from the March 2 SFN Launch Schedule
https://spaceflightnow.com/launch-schedule/

From the US Launch Schedule thread:
Scheduled:
Date - Satellite(s) - Rocket - Launch Site - Time (UTC)

2018

April 12 - AFSPC-11, EAGLE (ESPA Augmented Geostationary Laboratory Experiment): HTI-SpX, MYCROFT, CEASE-III-RR, ISAL, ARMOR - Atlas V 551 (AV-079) - Canaveral SLC-41 - 22:00-02:00

Changes on March 2nd
Changes on March 8th
