Commercial SAR Constellations
« on: 01/27/2019 12:41 am »
These things keep popping up.  In addition to ICEye and Capella, I've noticed:

Umbra: This one will be really interesting if they come anywhere close to their goals.  They are claiming a breakthrough in SAR performance (quarter meter resolution).

Oxford Space Systems released their new payload. Its pretty cool but it does not really fit into "new space" my back of the napkin says it will be 3x the cost of Capella or Iceye with the same performance. A little disappointing but cool design.

I was really sad to hear about the M.M.A. Design LLC v. Capella Space Corporation lawsuit.

Capella is getting sued by MMA for allegedly stealing MMA's antenna. The lawsuit seems really nasty as far as I can tell. Excerpts from the "PLAINTIFF M.M.A. DESIGN LLC'S RESPONSE IN OPPOSITION TO DEFENDANT CAPELLA SPACE CORPORATION'S MOTION TO DISMISS CLAIMS 1-4 AND 6 OF THE COMPLAINT" below:

"At the direction of Harvey, MMA's CTO and chief technical engineer, MMA proceeded to develop confidential and proprietary flight system requirements for a deployable, high gain reflectarray antenna (or "DaHGR") for Capella ("the Requirements")....

Within weeks, Capella officially broke off its relationship with MMA and immediately hired Harvey to spearhead the exact projects he had been designing for Capella through MMA.... Together Harvey and Capella designed and built the deployable solutions for Capella...

(Harvey telling Payam Banazadeh: "We will need to recreate the IP that I did at MMA in the last few years. The good thing is I know the map now and was exploring before to get the objective."). Due to its use of MMA's trade secrets and proprietary information, Capella obtained a technically complex high gain deployable thin membrane reflectarray antenna far faster and at much lower cost than it otherwise could have done and was able to secure significant funding from external sources it otherwise could not have obtained."

System Description:
On February 12, 2019, the Commercial Remote Sensing Regulatory Affairs office of the National
Oceanic and Atmospheric Administration, an agency of the Department of Commerce, granted a
license to Tyvak Nano-Satellite Systems Inc., a subsidiary of Terran Orbital Corporation, to
operate a private, space-based, remote sensing system named Tyvak-1022. Tyvak-1022 is planned
for launch into a 97.7° during the 2020 period. Tyvak-1022 is a Synthetic Aperture Radar (SAR)

Public Summary
YK-2018-L1

Licensee:
The licensee is York Space Systems LLC, which is located at 1449 7th Street, Suite 425, Denver, Colorado
80204, USA. Telephone: (720) 253-0464. URL: www.YorkSpaceSystems.com.

General System Description:
The licensed system is a synthetic aperture radar (“SAR”) remote sensing satellite system that will orbit
the Earth in a low earth orbit (“LEO”) at a nominal altitude of 500km and with an inclination of 40˚. The
Harbinger satellite will be capable of obtaining SAR images with a 3m resolution (GSD) and a 50km
swath width. The SAR will operate in the X-Band, TT&C also will be communicated in the S-Band and
data downlink will be in the X-Band.

Harbinger was launched already, the others are future launches.

I missed this story from last year:
[Space News, August 2018] Trident Space’s challenge: Standing out from the crowd of SAR satellite startups
Quote
One would-be player in this sector is Trident Space Inc. of Fairfax, Virginia. It plans to launch its first SAR smallsat in 2021, followed by six more satellites in 2023, and 12 each year thereafter, eventually building a 48-satellite constellation in low Earth orbit.
...
Trident Space is designing the satellites, including the bus structure, payload and electrical power system. ... “We expect to make a final decision on our manufacturing partner this year as we prepare to start the first flight unit for launch in 2020.”
...
Karangelen predicts Trident Space satellites operating in inclined orbits will have higher revisit rates than satellites in sun-synchronous orbits and will be capable of imaging through an eclipse. SAR smallsats will collect images from one-meter to 0.3-meter resolution.
...
 Trident Space recently completed an internal preliminary design review for its SAR smallsats. It concluded that the best option is a 300-kilogram satellite that is compatible with the growing lineup of commercial dedicated and ride-share launch options.



And here is another.
[Space News, July 2019] Japanese SAR startup Synspective reaches $100 million in funding
Quote
Tokyo-based remote sensing company Synspective said July 26 that it had successfully reached $100 million in funding since forming 17 months ago. 

Synspective is planning a constellation of around 25 small, synthetic aperture radar satellites for global coverage of the Earth.
...
Synspective’s first satellite, a 150-kilogram demonstrator, is slated to launch on an Arianespace Vega rocket in 2020, according to the startup.

Especially since japanese startups are traditionally fantastically underfunded at the angel/VC level compared to their american counterparts. The reverse is when the PE/bank managed funds suddenly pile in though. Everybody is chasing unicorns in this industry right now though, now that you have 2 rich guys effectively enabling the space industry to mature as a logistics system rather than bespoke transportation.

More info on Umbra Lab (Finally)

 If you actually do the math on http://umbralab.com their power aperture (10 square meter antenna, 60% efficacy, 500w in 50kg total mass.) is incredible - there is nothing else like it.

https://spacenews.com/umbra-opens-up/

Just look at the size of the gold mesh antenna (below).

SAR Journal added EOS SAR to their SAR Missions page, EOS SAR's first satellite offers about the same power aperture as Capella Space with a plan to improve their satellites significantly by 2024. I did not realize the same Will Woods (co-founder of Capella Space) is associated with EOS SAR which means he is bringing all his Capella knowledge and relationships to EOS SAR.

SAR startups are turning into a Soap Opera.

[Space News] Capella Space to launch seven radar satellites in 2020 as it prepares for commercial operations
Quote
WASHINGTON — Space-based radar imagery provider Capella Space will launch seven satellites and start commercial operations in 2020, the company announced Dec. 16.
...
The first satellite, to be named Sequoia, will launch from Cape Canaveral in March into a polar sun-synchronous orbit on a SpaceX rocket. The next three satellites are booked on an Indian Polar Satellite Launch Vehicle flight scheduled for June to a polar sun-synchronous orbit. These would be the first batch of a constellation to be named Whitney.

The next batch of three are being booked to go up late 2020. “We hope to finalize booking in the next few months,” said Banazadeh.

Capella Space Unveils Advanced Satellite Design to Deliver High Resolution On-Demand Earth Observation Data
Quote
...
A 3.5 meter deployed mesh-based reflector antenna combined with a high power RADAR enable key performance improvements including quality advances.
...
The new satellite design cemented major deals with multiple divisions of the U.S. government, including a contract with the United States Air Force and National Reconnaissance Office (NRO). The technological enhancements will be embedded in Capella's next six commercial satellites, named the "Whitney" constellation, starting with the launch of Sequoia slated for March of 2020. The Sequoia satellite is currently completing system level tests and will arrive at the launch site in early March.

Capella testing their electronics from an aircraft: "This STA covers testing of an experimental radar in an aircraft test. The radar is for a satellite system, but a short airborne test is needed to test the custom electronics. The spacecraft radar operation is covered by a separate FCC filing (0066-EX-CN-2018)."  The dates are March-August.
