Lesa Blade Ku band air terminal is a low-profile, fully electronically steerable antenna (ESA) with no moving parts. Designed for in-flight connectivity, the terminal enables short acquisition time and allows for high dynamic tracking enabling the best performance.
This compact solution supports all ranges of airborne platforms sizes to include wide-body aircraft, executive aviation, and rotary-wing operations, basically any in-flight connectivity. Its low-profile design makes it perfect for integration on any aviation platform to include already in place fuselage mount designs.
Lesa Blade includes a TX panel, RX panel, and an antenna management unit (AMU), allowing flexible installation options for different airborne applications.
Supports Multi-Orbit, Multi constellation architectures, enabling switching from GEO to LEO instantly, in flight.
A simple and intuitive solution that provides
multi-orbit SATCOM services, with the ability
to blend and transfer network traffic
seamlessly between high-capacity LEO (in KU
only), MEO (in Ka only), and GEO satellite
constellations
Integrated terminals include everything needed
for operation: modem, Antenna Control Unit
(ACU), tracking sensors, downconverter, and a full
RF front end.
Since there are no moving parts, calibration
is not required therefore providing
long-term reliability and lower maintenance
costs.
Extremely short transition time.
The significance of fiber-like connectivity
is a major step forward for high-data-rate
applications requiring communications
mobility.
Supports Global coverage networks, like
Intelsat in GEO, and other LEO networks, for near
seamless satellite coverage anywhere,
anytime.
The easy installation and integration of
the terminals, allows operators to
complete the process without the need
for time-consuming and costly visits of
technicians.
