Global wireless hotspot

A broadband satellite network to provide direct to user internet
services is possible. Similar to the satellite networks proposals of
the 1990s - such as Teledesic,

http://en.wikipedia.org/wiki/Teledesic

These satellites would each have a significant phased array antenna to
communicate with the ground

http://en.wikipedia.org/wiki/Phased_array

combined with an open optical laser link, to communicate satellite to
satellite with a 20 THz communications backbone.

http://en.wikipedia.org/wiki/Fiber-optic_communication
http://lasers.jpl.nasa.gov/

As the satellites fly overhead, they GPS signals to calculate control
signals for their phased array antenna system. Each phased array
antenna 'paints' a frequency corrected pattern of virtual cells -
fixed with respect to the surface of the Earth. In this way, a very
sophisticated and powerful satellite communicates with a large number
of simple (IEEE 803B compliant) wireless communicators.

A network of 660 satellites in 30 sun synchronous polar orbits (22
each) This URL is a visualization of Teledesic's proposed 288
satellite constellation (24 satellites in 12 orbits)

http://web.archive.org/web/199902091...tech/viz1.html

The proposed system provides 50 billion broadband wireless channels
that can be used to provide instantaneous communications anywhere in
the world. The satellites will be built in a factory intended to mass
produce them in large numbers. This will form the basic structure of
satellites and their components in the future - for production runs
beyond the initial 660 units. The satellites are expected to cost $20
million each in quantity. The factory itself will cost $4 billion.
A total of $17.2 billion for the payloads.

Satellite integration and launch is expected to cost an additional $30
million er satellite, aboard a new seven element RLV. This RLV
consists of 7 reusable propellant tanks equipped with cross-feeding.

http://www.astronautix.com/craft/bonhicle.htm

A 3,800 metric ton vehicle, consisting of 7 elements, each 500 metric
tons in mass, carrying a 300 metric ton reusable module, which itself
is capable of carrying 22 satellites, each 10 metric tons in mass.


http://www.pratt-whitney.com/vgn-ext...00c45a529fRCRD

http://www.astronautix.com/engines/aeroster.htm

Each 500 metric ton element is propelled by an annular aerospike
engine that uses three RS-68 pump-sets and control systems to produce
up to 910 metric tons of thust at lift off. Seven of these highly
throttlable engines operate at vehicle lift off, to put up one orbital
plane per launch, with complete recovery of the vehicle. In this
way, 30 launches put up the entire system in 15 months, with 21
vehicle elements, comprising 3 complete vehicles, with 7 element
spares (1 vehicle spare)

At $30 million per satellite, this is $19.2 billion for the entire
launch program, which includes vehicle development engineering, and
launch center construction near the White Sands Missle Range in New
Mexico. Once the 660 satellite have been launched and are
operational, this infrastructure continues to support satellite
operations as well as other operations beyond Earth. The reusable
satellite module, which is designed for aerodynamic re-entry into
Earth's atmosphere, may be adapted for use in Martian atmosphere to
support a manned operation to mars using the same launcher. Variants
would also support space tourism to orbit, and a tourist return to the
moon.

In all the $33 billion satellite network would return $50 billion per
year in revenues, with less than $0.5 billion spent on system
maintenance. (10 spares per year replacements - launched one at a
time with a 3 element system and a subscale re-entry vehicle)

An upgraded and 'stretched' version of this vehicle would deploy 500
metric ton powersatellite test articles into Geosynchronous orbit.
These systems beam IR laser energy to remote solar panel locations to
increase the value of large terrestrial power stations operated by The
Mok Companies around the world. Successful testing would begin
deployment of a network of 3,600 powersats in GEO each capable of
beaming 20 GW of laser energy to one of hundreds of sites throughout
the world - greatly expanding the energy resources of the global
community.

An advanced powersat designed for operation at an orbit 3 million km
above the solar surface, is also deployed by this launcher system.
Sending a payload to Jupiter which subtracts away nearly all its
orbital energy through gravity slingshot effect, the payload falls
almost directly to the sun. As it passes with 3 million km of the
solar surface, the spacecraft extends a large solar sail, which it
uses to lower its apoapsis to form a 1 hour circular orbit above the
solar surface. The test satellite when orbiting this close to sun,
tests out various methods of efficiently using the intense solar
energy found there, to manufacture 1 kilogram of anti-matter in less
than 3 years. The anti-matter powers an advanced rocket which brings
the entire assembly back to the lunar surface for testing and
evaluation. Over 800 kg of anti-matter are stored aboard the
spacecraft for use use in other missions. Primary, a mission to
Ceres - with the goal of reforming that dwarf planet to human use.

The wireless broadban system which provides real time communications
across the entire surface of the Earth, will make over $50 billion per
year from selling the basic communications services. Additional money
can be made by providing banking, insurance, management and security
services throughout the globe that are ill served now. In this way
underdeveloped regions and regions ill-served by existing governments,
can be better served by a wide range of commercial services. Over
$500 billion may be created in this way, while multiplying the wealth
of those being served even more dramatically.

Beyond these space research actvities and information intensive
services the company will also use profits earned from the network to
develop telepresence and telerobotic services.

http://en.wikipedia.org/wiki/Telerobot
http://en.wikipedia.org/wiki/Telepresence

This allows people to live anywhere and work anywhere else over this
service. This provides an additional $1,000 billion in revenue
capacity, while multiplying the value of the world some four times to
$240 trillion per year.

Lasers will only communicate where there is no clould. Why don't you
have a lower frequency system of pebbles where each pebbble can :-

1) Station keep like LISA. Each pebble would have a small ion drive
which would enable it to get from LEO to wherever it is going to end
up and station keep.

2) Have a large scale phased array where each spacecraft provided a
part of the input.

If you did this you would not have to do any heavy lifting. You could
in fact keep your spacecraft weight down to 100Kg or so.

That's why they are used exclusively to communicate between satellites
in orbit while a phased array microwave antenna is used to communicate
with systems on the ground.

Yes, you must've read my paper on smart smoke I wrote in graduate
school. There are scaling laws that dictate what is ultimately
achievable in this regard. Each scales differently, power systems,
communications systems, control systems, avionics, etc., etc., etc.
Create a multi-dimensional envelope as each develops.

Successful nanotech changes some of the envelope's edges - but that's
not the envelope we are working at today. What I propose is rather
straightforward application of today's technology.

You need a heavy lifter in any event.

Show me your calculations

I have not done detailed weght calculations. The question I am
essentially posing is what are the limits to divisibility. Your power
weight ratio is the same regardless of divisibility. There is one very
rough calculation I have done

http://www.telegraph.co.uk/money/mai.../ccview19..xml

"As thin as a sheet of paper". That is 80g/m^2 8Kg therefore gives you
100m^2 a hectare will weigh 800Kg. You have 2Kw/m^2 falling in space
say 500w@25% efficiency. This gives you Kw/Kg for the raw generation.
It does not tell you how much your microwave transmitters will weigh
of the various bits of control gubbins. I suspect they will dominate.
I have put this in because I believe that WiFi can develop into SSP.
The power requirements for simple WiFi are a lot more modest.

The minimum weight of an individual pebble depends on the processing
power needed. The rest can be scaled appropriately. My quote of 100Kg
is a guesstimate based on this. It is approximately (a little less)
than what the individual LISA spacecraft will weigh. My idea for a
telescope 1km in diameter is based on LISA's ability to manoever to
within a wavelength.

I have not read your paper, I have come to my conclusions
independently. Could I have a reference? The requirements are that the
pebble must be able to position itself accuately.

Pebbles need to be connected in hypercube topology. This (in effect)
means a number of laser beams criss crossing. Why a hypercube? Because
the basic algorihithm you need is the FFT and a "butterfly" is in
essense a hypercube. You take an FFT to transmit to each individual
PC, or WiFi hotspot and an FFT resolves the transmissions.

BTW - You will be flying above all the great firewalls. I speak German
and French fluently and have some knowledge of Spanish. Google
Translate is next door to perfect in those languages. If English/
Arabic or English/Chinese are to reach their full potential,
censorship will need to be tackled. Best way - fly above the pesky
firewalls!

Assuming that you are talking about the planned gravitational wave
detector LISA, let me dampen your enthusiasm a bit.

LISA is effectively a free-falling constellation. Free-falling,
because there are *no* manoeuvres as such. The only 'non-manoeuvres'
are to ensure the necessary rotation (!) of the spacecraft and to
****eract the solar pressure.

The distance between the spacecraft is 5 million km, varying by about
1% (!) over the course of a year, leading to relative velocities of a
few m/s.

There is neither attempt nor need for any manoeuvering to keep the
inter-spacecraft distance constant.

you have still measured to a fraction of a wavelength. If you are
constructing a conformal array you have a choice. You can manoever -
or you can simply put a velocity into the computer.


- Ian Parker

Sorry LISA is a gravitational wave detector. It has 3 spacecraft
arranged in a equilateral triangle whose side is 5m Km long. Lasers
measure the position to a wavelength.

I am interested in General Relativity in its own right, but there are
clearly technological impication of its accurate station keeping.

I'll stick with my system since I understand the details better.

OK but I think that if you really want to get your proposals accepted
you should look round at all the alternatives. OK at the end of the
day you may reject them for one reason or another.

I feel myself that pebbles are the only long term solution. In fact we
may simply be talking about granualarity. You are (in effect)
proposing boulders. Boulders will in fact have to perform FFTs as
well.


- Ian Parker

The only thing of any "Global wireless hotspot" is what's blowing out
your ass.

There's far better alternatives of fully terrestrial methods than any
spendy and unavoidably polluting satellite network can ever hope to
muster. Of H2 balloons or rather energy efficient robotic blimps
operating at perhaps as great as 75,000' are technically doable as is
(even doable if those robotic data/network blimps operated at
100,000'), and at not 1% the cost or pollution, and delivering at
least 100 fold the data and/or live smut throughput because of their
being so much closer to us internet users.

Besides your being a certified village idiot moron, you are nothing
but another infomercial spewing rusemaster of a bigot in every
possible way known to humanity, except somehow worse than.
