DTU to exam balloon communication with Swiss colleagues

Since final autumn, a communication system—known as Strato-link—has been tested successfully over brief distances. In a autumn, signals were sent over 190 km around a singular balloon, and, some-more recently, dual balloons were used over a brief distance. The new complement will now be tested with dual balloons over a stretch of approximately 1,000 km in team-work with a Swiss technical university EFPL in Lausanne, Switzerland.

The purpose of a exam is to settle how good a complement functions over distances analogous to approximately a same operation as satellites in low circuit around a Earth. If a exam is successful, a record might maybe be used for contrast in a stratosphere 10-50 km above a Earth, that currently requires assistance from ESA or NASA.

“Weather permitting, a devise is that in May we will launch a balloon here from DTU in Lyngby and a analogous balloon from EPFL in Switzerland. It is a stretch of approximately 1,000 kilometres, and a balloons strech a tallness of 25-30 kilometres. And we afterwards wish to be means to send signals and discuss behind and forth,” says René Fléron, MSc in Engineering and plan manager during DTU Space.

Collaboration between students from DTU and EPFL
René Fléron has grown a record together with tyro Andreas Rosenberg. They have sum commercially accessible record with satellite communications record grown during DTU. The new exam involves both experts and students from a dual universities in a initial approach partnership between a universities on a growth of new, innovative technology.

Strato-link is a sender/receiver section that creates it probable to promulgate directly over vast distances but regulating mobile phones or a Internet. The complement can be used for ground-to-ground communication around balloons during a tallness of adult to 30 km above a Earth.

The aim is to rise a long-range communications complement that can be used for tests achieved high above a Earth.

When a complement was tested final year, this was finished regulating a singular balloon. Via a balloon and Strato-link system, it was probable to discuss over 190 km between DTU in Lyngby and a automobile in Central Jutland, Denmark. And communication was recently determined over a brief stretch regulating a tandem complement consisting of dual balloons launched during a same time with a sum of 3 sender/receiver units and dual cars, as good as an earth hire during DTU, that any had one sender/receiver unit.

“The many new exam showed that we can hoop several balloons and sender/receiver systems concurrently. This bodes good for a Danish-Swiss exam subsequent month,” says René Fléron.

Laboratories in a stratosphere in a future
These tests are a step towards a investiture of laboratories borne by helium-filled balloons for use in a stratosphere. The thought is that a Strato-link complement can be used to promulgate with instruments in balloons that collect information in tie with studies or tests in a stratosphere.

In a prior tests, it has been probable to copy distances of adult to 1,900 km regulating supposed attenuators. But a apparatus contingency now uncover either it can indeed hoop such communication. Two teams on a belligerent in Denmark and Switzerland will try to send information to any other from earth stations around a dual balloons.

In further to this communication, a students from EPFL will try to collect information invariably from an examination conducted on house a balloon in Switzerland. The Swiss balloon is therefore versed with dual sender/receiver units.

“The new exam is to uncover partly that we can promulgate over ‘satellite-range’ distances and partly that we can hoop several sender/receiver units concurrently. It will be super exciting,” says René Fléron.
