AST SpaceMobile plans capacity of up to 40 MHz per beam on its commercial satellites to support 120 Mbps peak data rates.
Optical Surfaces beam collimators use a zero expansion off-axis parabolic mirror manufactured to better than lambda/10 p-v surface accuracy.
Optical Surfaces Ltd. supplied two reflective beam collimators to a leading European supplier of high precision optics to military and defence contractors.
Off-Axis Paraboloids are commonly used as collimators to produce a collimated beam from a point source in many optical systems.
Florida International University’s research team is working with Digital Locations to develop an antenna solution that dynamically adjusts for satellite positions, phase angle, beam forming, various satellite frequencies, and user conditions.
Optical Surfaces Ltd. developed an artifact suppression method that enables accurate magnification of small aperture laser beams using a 30x reflective beam expander.
Optical Surfaces Ltd.'s high-magnification reflective beam expander provides highly efficient transmission unspoiled by diffraction patterns.
Optical Surfaces Ltd. received a follow-up order from Magdalena Ridge Observatory to produce three second-generation off-axis beam compressors.
Optical Surfaces Ltd. previously supplied a 7.5x off-axis beam compressor that was designed to allow a 95-mm beam of starlight to be reduced in size for final division among instruments on the telescope.
Optical Surfaces Ltd. incorporates invar element tie bars in the beam compressor design to provide thermal stabilization.
The reflective design of Optical Surfaces Ltd.’s beam reducers is achromatic and, with protected silver coatings, can operate from the visible spectrum to the far infrared without adjustment.
The optical communications terminal aboard ALISIO-1 offers enhanced data transfer and increased security compared with traditional radio-frequency communication methods due to the narrow beam nature of laser signals.
Electronically scanned arrays provide fast electronic beam steering and a low-profile design ideal for mobile platforms and MEO/LEO operation but suffer from lower gain on GEO satellites.
ThinKom's VICTS antennas provide high beam agility that enables operation with LEO, MEO, GEO, and HEO satellite constellations, creating a multi-constellation, multi-orbit in-flight connectivity solution for airlines.
FreeFall Aerospace (USA) is developing stowable and deployable antenna technology with efficient beam steering to reduce satellite mass, power requirements, complexity, and costs, and is applying the same technology to ground antennas.
The toolkit simulates reconfigurations of steerable beam capacity to meet demand variations.
Phased array antennas use electronic beam steering to direct beams to precise locations and improve system reliability.
Blu Wireless unveiled PhantomBlu as the first fully integrated LPD V-Band radio node that delivers 360° beam-formed communications coverage.
MDA offers a family of digital beamforming-enabled electronically-steered direct radiating arrays that address multiple non-geostationary orbits and frequencies, provide direct RF conversion, and include native beam hopping capability compliant with DVB standards.
MDA will build a digital beam-forming antenna, the spacecraft bus, and an onboard processor of its own design for Lightspeed rather than leveraging Thales Alenia Space’s antenna design.
