Electromagnetic Sensing for Space-Bourne Imaging
• Previous offerings have studied IR and Visible imaging systems that can be used to obtain high resolution imaging of space objects.
• As in last year, this semester will look at a new but related interest: Microwave energy propagation.
• To provide examples, consider design applications of Solar-Microwave Fabric and Power Star – Two red hot inventions garnering lots of private investment.
• Learn the needed background on optics, microwave reception, transmission and phased arrays.

Spring 2014 Design Challenge
• Design a space-based Solar Power System (SSP)– One or more satellites that collect solar power– Solar power is converted to microwave radiation– Microwave radiation is beamed to several places on the
ground by means of a phased array– At each reception station the power is converted to DC
via a rectifying antenna (rectenna) array– Power is distributed locally, without long-distance
transport.– Focus should be on a First Revenue System
• We will be assisted by DoD consultants and SSP entrepreneurs

Spring 2015 Design Challenges
• Explore the Power Star System design in more depth (building on Last Year’s work)
• Study additional applications of the core invention: Solar-Microwave Fabric.– Portable power system for inaccessible locales– Rapidly deployable air defense system– Power and communication system for space
exploration

Solar Constant
= rate of energy intercepted by one square meter at normal incidence in space at 1 AU from the Sun
= 1367 W/m2
This means you can collect 12 MW-Hrs. in a year, in space
Source of Ground-level attenuation
Attenuation Factor
Atmospheric (absorption & weather)
~0.6
Average inclination ~0.5
Day/night 0.5 to 0.25
Net attenuation
~ 0.15 to 0.07
So, collecting solar power in space (if you can do it) could be much more dependable and efficient.
Once you learn how to do it, Space Solar Power might be more efficient...

Background
• All previous SPS concepts– Involve gigantic, complex, articulated structures– Contain numerous, perhaps 1000s, of moving
parts– Require numerous launches– Require on-orbit fabrication/construction, usually
robotic– Involve serious dynamic stability issues
• Power StarTM combines very new and very old technologies to obtain:– The simplest possible structure– No moving parts (except electrons and photons)– One launch vehicle (A one-km system can fit into
several existing vehicles)– No on-orbit construction– Inherent dynamic stability and robustness

Heinlein Prize Trust Announces New Solar Power Concept at IAC Toronto
Heinlein PrizePosted Friday, September 26, 2014
The Robert A. and Virginia Heinlein Prize Trust (HPT) will unveil a new space solar power concept that it is assisting in developing at the 65th International Astronautical Congress (IAC) held at the Metro Toronto Convention Centre Tuesday 10:30 a.m.
This new space solar power satellite was developed by Dr. Dave Hyland, Professor of Aerospace Engineering and Physics at Texas A&M University and Dr. Haithem Altwaijry, Director of the National Center for Remote Sensing Technology at King Abdulaziz City for Science and Technology (KACST). It uses a simple, robust structure, requires no moving parts or on-orbit construction and only requires one launch vehicle to deploy an operational system.
“Space solar power will be an important component of the new space economy,” said HPT Trustee Arthur M. Dula. “This new space solar power concept can provide clean, efficient and cost-effective way of supplying power to the Earth and development of human civilization in space.”
The press are invited to a presentation and Q&A session regarding the new invention at the HPT Exhibit at the IAC exhibitor hall (Booth #137) on Tuesday 10:30 a.m. For more information regarding the event or to RSVP for the press announcement contact Buckner Hightower +1 (512) 363-2279 or email [email protected].
About the Heinlein Prize Trust: The Robert A. and Virginia Heinlein Prize Trust honors the memory of Robert A. Heinlein, a renowned American author. The purpose of the Heinlein Prize is to encourage and reward progress in commercial space activities that advance Robert and his wife Virginia’s dream of humanity’s future in space.

Message from AIC-SVC CEO and Investment Management Group -Excerpts
“…this is now the most promising idea – by far! We can now envision the production of a first-revenue system in one launch. This closes the business case!!”
“…my management group and I have been working with Dr. Hyland to enlist private venture capital for his projects. So far we have been offered $150 million for a five-year effort to develop and produce the first Power Star satellite. Further, we are canvassing ten additional investment groups!!
“…you can be part of our team! I cannot exaggerate the benefits to you that will result from your participation in the hottest, most advanced, and most feasible solar power innovation so far conceived!
Very best wishes,S. P. Boike, CEO and President,American Industrial Consultants and Solutions Vehicles CompanyLong Beach, California
