CASE STUDYAtmospheric Propagation Modeling
Quartus has delivered and commissioned a complete ground terminal and low earth orbit optical head for free space laser communication.
Quartus was heavily involved in requirements definition and systems engineering, including the optical link budget.
In order to determine if atmospheric effects could be sufficiently corrected by incorporated adaptive optics, Quartus performed atmospheric modeling using internally developed wave propagation tools, MODTRAN, and HELEEOS.
