Helikites Lift Spearnet Radios to 200ft

Low Visibility Skyhook Helikite, Lifts ITT Spearnet Radio to 200ft
On Friday 19th October 2007, a small, three cubic metre, Low Visibility Skyhook Helikite lifted an ITT Spearnet Radio to 200ft above Allsopp Helikite’s flight-testing grounds.
Each Spearnet radio acts as a relay to every other radio to automatically create a mobile, ad-hoc, internet-protocol network.
Skyhook Helikites are a new type of all-weather, high-altitude, tethered aircraft. Helikites are unique because they are the only aerostats in the world that are pushed up by both helium and by wind. This means that very compact Helikites are highly weather survivable. Helikite systems provide an inexpensive, all-weather, and permanent aerial platform. Everything needed to lift the Spearnet radio to 1,500ft for many weeks only weighs 15kg and can easily be fitted into a small rucksack. This includes the Skyhook
Helikite, helium cylinder, flying line, and reel.
With the 300 Milliwatt SpearNet radio at 200ft, good line of sight reception was reached out to six miles between hills. This was an area about 100x greater than the radio would perform alone.
These radio waves can carry a lot of information, including real-time video. However, the high band width, high frequency radio waves required for this cannot bend around terrain. Therefore, without a high altitude relay they are normally restricted in range to less than 0.6 miles.
With a Skyhook Helikite, a single soldier can create a large, reliable, and widespread network in a couple of minutes – from just one position. Currently, achieving the equivalent requires hundreds of soldiers to fight and capture every hill in the district for radio-relay purposes, and then needs hundreds more soldiers to constantly defend them from attack. The use of a Skyhook Helikite instead is a no-brainer.
This test was carried out with the Helikite flying at only 200ft, which is the legal altitude limit. However, there was enough spare lift to have flown the 700g radio to 1,500ft, if allowed. This correlates with previous unconnected radio-relay tests in the USA using similar Helikites flown to 1,500ft that sent packet video data 61 miles in flat terrain and provided excellent coverage in hilly areas.
Therefore, this is a significant event. For the first time ever, there is a very simple and practical way to spread the full power of the internet over the full surface of the land or sea without the need for expensive infrastructure.
This makes possible the deployment of unmanned ground vehicles and unmanned sensors anywhere in significant numbers, and to be permanently controlled from any position in the world via the internet. Other ad-hoc, hand-held radios are also highly suitable, such as Raytheon’s Microlight® or Cobham’s Eagle® Radio.
And its use is not confined to just the military.
New, civilian-oriented MANET radios lifted on small Skyhook Helikites allow anyone to create their own instant, long-range, internet protocol radio network. This is practical for civilian users such as fire-fighters, coastguards, police, loggers, mineral surveyors, mountain rescue, etc.
