High-speed, high-capacity VSAT service for medical services, armed forces, emergency and privately-owned helicopters now available after extensive development

MOST announces the commercial availability of the MKu30H, the new system connectivity to internet, video, and voice service for helicopters which resolves a long-term challenge for the industry.

Broadband coverage under the blades is now available.

For helicopter crews, the use of internet, video, and voice service is vital for sharing information about what is happening on the ground and other airborne vehicles, for example in areas of conflict and natural disasters.

Previously helicopters used a mixture of cellular and low data rate satellites to communicate with people on-the-ground and other airborne vehicles, however, neither technology is well-suited for high-altitude helicopters and fixed wing aircrafts.  Cellular has three drawbacks: signals can only reach about 500m above ground level; devices are often required to roam over different networks whilst the helicopter is moving over longer distances and thirdly, cellular can be unreliable or unavailable outside urban areas and especially in mountain, desert and sea situations where helicopters are often deployed in emergency situations.

Likewise, low data rate satellite services are only able to provide low-bandwidths to any kind of moving vehicle – and for helicopters there is the added problem that such low data rate satellite antennas see the sky with reduced data rate because of the helicopter blades acting as a ceiling and chopping the satellite signal.

After extensive work by the R&D teams at MOST, in June 20 the company completed comprehensive tests of the new MKu30H system.  MKu30H provides exceptional data speeds at very economical expense. Data rates of about 2Mbps uplink and 2Mbps downlink have been achieved on regular basis. Now, each helicopter equipped with MOST MKu30H antenna and modem connects internet, video, and voice to any standard satellite ground HUB station around the globe. 

MOST CEO Zack Berejik said: “We have cracked a long-term problem for the industry; how to provide GEO connectivity under the blades. Now we are able to provide economical cost, high-speed service that enables internet and video in real-time. This will be important for instance in emergency medical situations where the use of internet and video whilst an injured person is on a helicopter, it can be a life-saver”.


MOST specializes in the provision of broadband solutions for fixed and rotary wing aircrafts as well as unmanned aerial vehicles (UAVs). MOST is one stop shop for advanced mobile satellite technology with all its satellite antennas and modems developed and manufactured “in house”.
