Financial and Organizational Analysis for a Space
Solar Power System - Toulouse, France
new paper on space solar power has just been added
to the online NSS Space Solar Power Library. The
paper is: “Financial and Organizational Analysis
for a Space Solar Power System,” May 18, 2009, 225
pages, 3.7 MB PDF.
Peter Garretson, NSS Director and one of the principal
authors of the Department of Defense report Space-Based
Solar Power As an Opportunity for Strategic Security
“This is the first modern paper to
include a stakeholder analysis, an in-depth discussion
of international organizational aspects (including
intellectual property and separation of manufacture
and operator companies), and Net Present Value calculations
of niche systems (such as front-line military power).”
Authors of the paper are Sun Xin, IT Director
of the China Academy of Space and Technology; Evelyn
Panier, Finance Application Consultant; Cornelius
Zund, Control Systems Engineer at Pratt & Whitney
Canada; and Raul Gutierrez Gomez, Lieutenant Colonel
in the Colombian Air Force and Planning Director
of Military Aeronautical Institute.

is a minimum of atmospheric signal attenuation in
the range of 2.45-5.8GHz, and also 35-38GHz. Specifically
we might expect losses of 2-6%, and 8-11% respectively.
We will use a transmission frequency of 38GHz since
this allows us to transmit the most energy into
the smallest space, even when accounting for transmission
"7) We will use a transmitter diameter
The combination of transmitter size and frequency
result in a relatively small rectenna diameter when
compared against the ESA reference system"
"Linked to the cost of the launcher is the needed
mass of the system. The satellite mass value of
3137Kg/Tm used in our calculations added a considerable
amount of mass for larger transmitter diameters,
leading us to select a higher frequency of transmission
(38GHz). This choice allowed us to afford a smaller
antenna / rectenna combination, however substantially
increased energy transmission density. The diffuse
energy density offered with a 2.45GHz system required
a massive increase in rectenna size, and offered
no benefits in terms of cost."
