Our New Homepage Has Been Launched, Please Explore
MIRAD is very happy to announce the launch of our new homepage. Please, feel free to explore and contact us with your inquiries. Thank you!
Ka-Band High Performance Feed
Ka-band feed system
ViaSat-1 is a HTS (=High Throughput Satellite) owned by Viasat. Launched in 2011, it is the world's highest capacity communications satellite with a total capacity in excess of 140 Gbit/s, more than all the satellites covering North America combined, at the time of its launch. The significant increase in capacity is achieved by a high level frequency re-use and spot beam technology which enables frequency re-use across multiple narrowly focused spot beams (usually in the order of 100s of kilometers).
X-Band High Power and Low PIM Feed
X-band high power / low PIM feed system integrated into feed can
The high power / low PIM X-band feed provided for a governmental application is WGS (Wideband Global Satcom) compatible.
S-/X-/K-Band Feed
S-X-K feed system
New antenna system for the German space center (DLR) ground station in Neustreliz for the reception of data from remote sensing satellites (LEO and GEO).
Galileo S-Band Feeds TT&C
S-band feed system with feed can
The Galileo Project is Europe's initiative for a state-of-the-art global satellite navigation system, providing a highly accurate, guaranteed global positioning service under civilian control. The fully deployed system will consist of 30 satellites and the associated ground infrastructure.
X-/K-Band Feeds for DSA2 & DSA3
Water cooled X-/ K-band feed system integrated into feed can
The European Space Agency (ESA) runs several scientific exploration and research deep space missions e.g. Rosetta, Mars-Express, Venus-Express or space observatories like Herschel or Planck. To ensure a reliable communication with such deep space probes, ESA has built up a ground station antenna network all over the globe.
Switching & Combining System
Ku-band 9:2 channel switching and combining system
In order to bundle the many different TV channel signals to a limited amount of antennas, high performance Tx switching and combining systems are required to guarantee a continuous operation. Therefore during the last two decades MIRAD has not only been the prime provider of various feed systems for SES’s ground station antenna parc in Betzdorf, Luxembourg, but has also designed and manufactured a large amount of complex switching and combining systems, often consisting of 2x9 channels.
European Data Relay Satellite System (EDRS)
EDRS feed system
The European Space Agency (ESA) is positioning several data-relay satellites in the geostationary orbit to relay information between non-geostationary satellites, spacecraft, airborne platforms and fixed ground-stations. The EDRS reduces time delays in the transmission of data intensive and time critical applications and ensures on-demand data availabilty at the right time at the right place.
Q-/V-Band Feed
Q-V-Band feed system
The Alphasat I-XL, launched in 2013, included beyond its main task several ESA TDPs (Technology Demonstration Payloads). TDP5 includes a Q-/V Band communications experiment to assess the feasibility of these bands for future commercial applications.
XAAE X-Band Antenna Assembly
XAAE feed horn antenna
The XAAE is a part of the Egyptsat X-band antenna assembly, which consists of two redundant on-board 2-axis antenna pointing mechanisms (APM).
