High Bandwidth Flexible Satellite communication System for 1 Gigabit/sec communications

Project description

High-bandwidth antenna could revolutionise satellite communications

Ka-band is changing the face of satellite communications, offering data transmission rates hundreds of times faster compared with S-band. The EU-funded HIGDARS project plans to develop a broadband telecommunication system for small satellites that operates in the Ka-band frequency range, thereby allowing for the use of smaller antennas. In particular, the researchers will develop an expandable high-bandwidth parabolic antenna with smart error correction and optimisation. The new antenna will be foldable and will eliminate the need for any mechanism or mechanical parts. A sub-reflector will be able to change its own shape to adapt beam shaping for optimum Earth coverage.


HIGDARS- High Gain deployable adaptable reflector for satellites.
The objective of the HIGDARS project is to develop a commercial Broad band Telecommunication system in KA band, for small satellites at first, using an innovative Expandable High Bandwidth parabolic Antenna with a smart error correction and optimization (Beam Shaping) sub reflector.
Using the advancement in materials, a low mass and small volume when stowed antenna is being developed made of SMP (shape memory polymer). The material allows for a very low mass fold-able antenna that requires no mechanisms or mechanical parts.
In addition, an innovative feed system for KA band in a cubesat is being developed with an adaptive sub reflector.
The sub reflector with the help of many Piezo actuators and flexible reflective surface is able to change it's own shape and thus optimize the main reflector and also perform beam shaping for better and flexible coverage on Earth.
This system demonstration will be able to provide a link of 1 Gigabit per second from a 6U cubesat. this is 500 times the best systems available today (providing from 0.25 up to 2 megabits/sec).Applications such as HDTV, Ultra HDTV (4K), Mobile TV, In-flight Internet, Fast Internet, and bi-directional satellite to cellular device communication, amongst others, are driving insatiable demand for satellite communications bandwidth. This demand pushes satellite manufacturers to build satellites with bigger Antenna sizes, higher transmitting power and higher receiver sensitivity. The new small satellite constellation companies are offering continues large amounts of data, imagery and communications, all needing a high level link not available today for these satellites. In the small satellite (cubesat) constellations large Parabole Antennas do not exist, the antennas are still either tape measure, or patches. An innovative technology is needed to both address the technical challenge and enable further expansion of satellite services.
