The world of High Altitude Airships
|"Lockheed-Martin" HAA High Altitude Airship Haute Altitude Airship|
the Long Endurance Multi-intelligence Vehicle (LEMV) program for an earlier
blog led me to wonder what had become of another
surveillance airship, Lockheed Martin's High
Altitude Long Endurance Demonstrator (HALE-D), which was
supposed to have flown this summer. I hadn't heard anything, so I
asked. Turns out it didn't fly, but the envelope was
inflated inside the Airdock
seems the program ran out of money before the airship could be flown,
and Lockheed says it is now working with the US Army's Space &
Missile Defense Command to find additional funds to complete the
Delivering Disciplined Performance
Lockheed Martin is currently on contract to build a subscale prototype airship system, the High
Altitude Long Endurance-Demonstrator (HALE-D). The performance goals for this prototype
HAA include sustained operations for at least two weeks at 60,000 feet altitude, while
providing 500 watts of power to a user-defined 50-lb payload suite. Driven by two electric
propulsion motors, the HALE-D is powered by thin-film solar cells and rechargeable lithium
ion polymer batteries. The HALE-D will demonstrate long-endurance station keeping and flight

LOCKHEED MARTIN AWARDED $10 MILLION TO DEVELOP DARPA'S STRATOSPHERIC AIRSHIP FABRIC AKRON, OH, September 26, 2006
AKRON, OH, September 26, 2006 -- Lockheed Martin [NYSE: LMT] has received a contract for approximately $10 million to further develop advanced material technology and next-generation hull material for stratospheric airships under the Defense Advanced Research Projects Agency (DARPA)’s Integrated Sensor Is Structure (ISIS) program.

have been flying in hot air balloons and dirigibles far longer than
there have been airplanes and space shuttles. So it's not surprising
that the US military
is looking at airships (such as stratospheric floaters) as the
platforms. After all, airships seem to be becoming
more popular these days.

Un dirigeable pour émettre du haut débit ? mardi 11 décembre 2007
Et si le haut débit prenait de la hauteur ? C'est en tout cas l'idée d'un groupe de chercheurs qui veulent utiliser un dirigeable comme relais-émetteur.
Depuis plus d'un an,
des équipes suisses et britanniques travaillent sur le projet
"X-Station". Derrière ce nom de code se cache un projet
tout droit sorti d'un James Bond. Les scientifiques veulent
transformer un dirigeable de 100 mètres de long en véritable
station haut débit !
Peu onéreuse, abordable et rapide à mettre en oeuvre" selon Kamal Alavi, ingénieur responsable du projet, la solution X-Station devrait intéresser les pays en voie de développement qui ne peuvent pas financer des réseaux haut débit classiques, bien trop chers. Quelques ballons pourraient couvrir de vastes superficies, et résoudre en partie la fracture numérique entre les pays de l'hémisphère Nord et ceux du Sud. Les premiers tests grandeur nature auront lieu dans quelques jours avec un prototype de 30 mètres. La commercialisation des ballons sera lancée d'ici 2 ans si tout se passe bien.
Fund for poor country IT projects eyes high tech airship March 20.2007
GENEVA (AFP) - A solar-powered airship that replaces communications satellites is one of a series of high tech projects that can help bridge the "digital divide," the organisers of an Information Technology fund for poor countries said Tuesday.
The Digital Solidarity Fund was launched by African leaders and European public authorities at a UN summit two years ago to bring modern communications to an estimated 80 percent of the world population in por countries that are unconnected.
The Fund said at a board meeting that a dozen community-based projects in Africa and one in Asia had got off the ground.
They mainly involve teleconferencing facilities for medicine and education.
However, the Fund is facing further financing requests for projects worth 26 million euros, officials told a board meeting.
More political support is also needed for nascent technology that can save huge amounts of money if deployed in developing nations in the next decade, they added.
Swiss researchers unveiled the X-Station at the Fund's board meeting, a solar-powered, pilotless airship stationed at an altitude of 21 kilometres that can bring high speed telecoms services to an area 1,000 kilometres in diameter.
The project developed by a joint venture of universities and companies is due to be tested later this year.
"It will be cheap, affordable and fast. You don't have to spend millions of dollars to launch communications satellites," said founder Kamel Alavi.
US technology giant Sun Microsystems also presented a centralised Internet-based server that can effectively do away with 10,000 personal computers and equips the end users with just a screen and keyboard.
"It is five percent the size of its father, it consumes a fraction of the energy, it is deployable in a tenth of the time, and it is mobile," said Mary Smaragdi, director of Sun's Foundation.
Members of the Fund -- currently 24 countries, eight local authorities, and private companies -- make a one-off contribution.
Another key, though still voluntary, source of funding is a one percent charge on information technology (IT) purchases made by members.
However, more public authorities that would like to join face legal constraints with rules on public tenders, especially in the. An international convention might be needed to overcome the problem, officials said.

|"TECHNOSPHERE" HAA High Altitude Airship Haute Altitude Airship|
September 28, 2007 Cyber Defense Subsidiary Techsphere Systems to Build New "BULLET" Airship Technology for Mid Altitudes; New Prototype Test Flight Successful
Cyber Defense Systems, Inc. (OTCBB: CYDF), a designer and developer of next generation unmanned aerial vehicles (UAVs), and its wholly owned subsidiary Techsphere Systems International, Inc. (TSI), a designer, developer and manufacturer of manned and unmanned airships, announced today that it will build two new Mid Altitude "BULLET" Airships.
Under the exclusive global technology license with 21st Century Airships, Techsphere will begin manufacturing two "BULLET" airships designed for altitudes of 20,000 and 40,000 feet capability with a minimum of 48 hours flight duration with estimated speeds up to 60 knots with a manned or unmanned configuration. Recent wind tunnel tests by 21st Century confirmed the design and speed estimates.
The initial test flights were exceptional utilizing a fly by wire thrust vectoring capability. "Just imagine being able to fly straight up and down, turn on its axis, and fly sideways with an easy touch of a joystick," stated Hokan Colting of 21st Century.
The airship tested is approximately 120 feet long, cylinder shaped with two distinct pointed end caps with four engines mounted port and starboard in the fore and aft positions on the cylinder structure.
Techsphere will be utilizing the majority of the patented technologies from the spherical technology with the new "BULLET" version for Mid Altitudes. "The SA-60 spherical airships will continue to be our bread and butter for the 0 to 10,000 feet altitude capability. We are addressing the higher winds between 10,000 feet to 40,000 feet altitudes with a new shape for drag reduction, longer duration of flight, higher speeds with the maneuverability characteristics of the 'Sphere' technology," stated Mike Lawson, CEO of Techsphere.
The "BULLET" test flights will continue later this year with the second prototype near completion.

13 July 2006 New "Paint-On Antenna" Flies Successfully on Sierra Nevada Corporation Techsphere Airship
for Next Generation Communications and Remote Sensing Systems
National Aeronautics and Space Administration (NASA) Langley
Research Center , RTI International, Applied EM, Inc., International
Communications Group, Unitech, Sierra Nevada Corporation (Sierra
Nevada), and Techsphere Systems International, Inc. (Techsphere), a
wholly owned subsidiary of Cyber Defense Systems, Inc.,, announced
today that the test flights of the new generation "paint-on"
antenna technology on board the SA-60 Spherical Airship were
successful June 21, 2006 in the Nevada desert.
was a worldwide exclusive to test the lightweight "paint-on
antenna" technology on Sierra Nevada and Techsphere airship
technology for communications and other applications. As part of an
effort to develop new high-altitude communications and surveillance
platforms, Applied EM, Inc. and Unitech, LLC are developing
conformal "paint-on" antenna technology under an Air Force
Small Business Innovative Research (SBIR) Program (Air Force
Research Laboratory, Hanscom AFB). "Paint-on" antenna
designs were used in the Airship flight test for Iridium Global
satellite communications from several locations on the Airship.
These antennas transmitted and received voice and data links via the
global Iridium satellite system and overall radio frequency
performance was outstanding. Iridium bit error rate data
transmission and receptions were tested and voice communications to
and from the Airship with teleconferencing were tested successfully.
addition, the Airship flight experiment included NASA's GPS
Reflectance Experiment, which was flown to evaluate Airship
applications for soil moisture remote sensing missions. The NASA
Langley Research Center (LaRC) is developing remote sensing
applications of the Global Positioning System (GPS). While
originally designed to relay navigation data, the
satellite-transmitted GPS signal itself may be used to obtain a
number of useful scientific measurements of both the earth's surface
and of the atmosphere. This new technique utilizes the reflection of
GPS signals from water, wet ground, or artificial conducting (metal)
bodies. Researchers at Langley, in concert with their colleagues
around the world, are developing theory, designing instrumentation,
and conducting experiments to better understand the properties of
the surface reflected GPS signal. The goal of the project is to
apply the knowledge gained toward the development of low-cost,
easily deployed, and widely applicable remote sensing systems.
moisture is a relatively small component of the global hydrological
cycle, but of great importance, nonetheless, in the development of
it. Soil moisture is water in the ground and, as such, it plays a
critical role in many biological and hydrological processes such as
plant health, nutrient cycles, and cloud formation. The accurate and
timely measurement of soil moisture content and its fluctuation is
of paramount importance in the monitoring of natural hazards such as
flooding and drought. The amount of water in the soil affects the
transfer of energy between the surface of the Earth and the
atmosphere by creating weather systems that can affect large
populated areas. A highly water-saturated soil, for example, cannot
absorb as much water as dry soil and can easily create runoff or
flooding. The existence of an accurate map of soil moisture would
provide information for agricultural efficiency, water management,
disaster planning, and many other indirect applications.
despite the fact that soil moisture measurements have been
recognized as a priority in Earth science, continuous and
far-reaching measurements are all but nonexistent. Present methods
of measuring soil moisture, though accurate, are insufficient for
use in forecast models to prevent disaster or to complement the
understanding of the water cycle. However, the monitoring of soil
moisture by means of remote sensing remains a topic of research and
development rather than an operational capability. The recent launch
of the satellite Aqua and the current development of new Earth
looking systems, like the GPS reflectometer presented in this site,
promise to provide better measurements of soil moisture to improve
the understanding of nature and the quality of life on Earth.
brought the team together as part of NASA's Innovative Partnership
Program (IPP) to demonstrate the overall capabilities of high
altitude airships for numerous NASA research applications. "The
successful airship test flights demonstrate exciting possibilities
for 'paint-on' antenna technologies," said David Myers, vice
president of RTI's Engineering and Technology Unit. "This new
technology can be used to assist with hurricane disaster relief,

|"STRATSAT" HAA High Altitude Airship Haute Altitude Airship|
Hi-tech mission for airships Wednesday, 27 February, 2002
Airships could provide a cheap and quick way of bringing mobile phone networks and fast internet connections to remote parts of the world.
Engineers at Britain's Advanced Technologies Group (ATG) are working on developing airships that could provide the telecoms networks of the future.
Their StratSat programme applies modern technology advances to the old principles of airships to offer what they believe is a cheap and flexible alternative to unsightly mobile phone masts across the countryside.
"It's bringing airships out of the thing that you see over sports stadium just doing a bit of camera work or advertising and making them part of the 21st Century and data communication," Mike Durham, senior technical consultant at ATG. http://news.bbc.co.uk/2/hi/science/nature/1840936.stm

Balloon beams broadband internet from stratosphere 19 October 2005
A blisteringly fast data downlink provided by a stratospheric balloon floating 24,000 metres above the Earth has been tested for the first time.
The untethered, 12,000-cubic-metre helium balloon was tested on 31 August for several hours. Analysis now shows the test was a success and sent data to the ground at 1.25 gigabits per second. That is thousands of times the capacity of a home broadband internet connection and the first time such a link has been tested from the stratosphere.
The test craft was developed by the Capanina Consortium – 14 European academic and industry partners funded mainly by the European Union. They hope the craft may be able to provide communications in disaster zones or low-cost internet access in the developing world.
David Grace, one of the project scientists behind the test, from the University of York, UK, says stratospheric communications balloons provide wireless alternatives to fixed internet infrastructure. "You could rapidly put communications infrastructure where it doesn't exist," he told New Scientist. "In developing countries it could be a cheaper way to roll out, and you could do it incrementally."
The main concern with such floating communications hubs is ensuring they do not interfere with commercial aircraft. Controllers on the ground are able to alter the altitude of the balloon but not steer it.
The stratospheric craft was equipped with two communication systems: a high power radio antenna developed at the University of York, and an ultra-high-speed optical communications system built by the German Aerospace Centre (DRL).
The balloon's radio link was based on the 802.11b protocol. This is normally employed in Wi-Fi computer networks that extend a hundred metres or so. For the balloon test, powerful millimetre-frequency radio antennas were used, to send the signal up to 60 km. This link was used to transmit data rates of up to 11Mbits/sec.
The optical communications link developed by DRL was only tested from the balloon to the ground. It transmitted data around 100 times more rapidly. In future it should be possible to develop a bi-directional link based on this technology.
Both communications systems rely on pointing a directional instrument at the balloon. "Tracking is a key issue in stratospheric broadband," says Alan Gobbi, also at the University of York. At the high altitude of the test, Gobbi says the balloon drifts about a kilometre over a few hours, depending on conditions. In the future, larger balloons could float for weeks or months at a time, providing a quick and simple communication link.
The York team used Global Positioning System (GPS) data and a modified telescope to track the balloon as it drifted. Video footage (28MB Mpeg) recorded at the test site – the Swedish Space Corporation's space centre at Esrange, 200 kilometres below the Arctic Circle – shows the University of York researchers testing the optical tracking system on the balloon.
The Capanina group is also investigating other types of high-altitude communications craft. Large airships could perhaps carry heavier communications equipment into the skies, while fleets of solar-powered aircraft could circle at high altitude for long periods http://www.newscientist.com/article/dn8177.html
Surfez en ballon dirigeable ! 15/07/2004
Un projet européen nous permettra peut-être de surfer sur Internet à haut débit en utilisant des ballons situés dans la stratosphère.
On avait les câbles, les satellites, les ondes... bientôt on aura les ballons et les dirigeables. C'est tout à fait sérieux : un projet européen teste actuellement la possibilité d'utiliser des plates-formes aériennes à base de ballons et dirigeables pour fournir du haut débit. 120 Mb/s ! De quoi faire de la vidéo à la demande, de la vidéoconférence, des jeux en réseaux, de la simple navigation sur Internet... tout cela sans polluer notre brave planète. Non seulement les ballons et dirigeables n'utilisent pas de carburant mais en plus leurs dispositifs seront alimentés par énergie solaire. Situés dans la stratosphère, c'est-à-dire à une vingtaine de kilomètres d'altitude où les nuages ne sont pas à craindre, ces aéronefs tourneraient autour d'un point central fixe et couvriraient une soixantaine de kilomètres de diamètre au sol.
Pas de risque de collision avec nos bons vieux aéroplanes, les ballons et dirigeables "se situent bien au dessus de nos avions et bien en dessous des satellites", précise-t-on chez Capanina, consortium à l'origine du projet qui réunit treize partenaires européens et un en provenance du Japon. En plus, contrairement aux satellites qui, une fois consommés, sont bons à jeter à la poubelle (en fait ils se désagrègent plus ou moins dans l'univers), les ballons pourront être récupérés pour maintenance et relancés. Bref, de quoi se payer une belle tranche de surf "propre" sur la toile sauf qu'il faudra encore attendre un minimum de cinq ans pour voir les premières applications grand public...http://www.indexel.net/1-20-3808---/index.htm
