Fade Analysis of ORCA Data Beam at NTTR and Pax River
The DARPA Optical RF Communications Adjunct (ORCA) program was designed to bring high data rate networking to the warfighter via airborne platforms. Preliminary testing of the ORCA free-space optical communication (FSOC) laser beam was performed on May 12, 2009 by the Northrop Grumman Corporation (N...
