Adil M. Karim is a member of the Senior Professional
Staff in the Electro-Optic and Infrared
Systems Group in APL’s Air and Missile Defense
Department. His technical interests include fiber
optics for antenna remoting, microwave photonics,
optical component design, and fiber-optic sensing.
He was the fiber optics technical area lead for the
project described in this article and is involved in
a number of other fiber-optics programs at APL.
Stephen J. Stafford is a member of the Senior Professional Staff in the Force Projection Department. Since joining the
GNSS and SATRACK Systems Group in 2005, his work has included the development of signal-processing techniques
for radio navigation. His work on this project included development of algorithms for recovery of GPS message segments
received from multiple antennas. R. Benjamin Baker is a member of the Senior Professional Staff and a Section Supervisor
in the Force Projection Department. His technical interests include high-frequency monolithic microwave integrated
circuit (MMIC) design, high-efficiency microwave power amplifiers, and microelectronic assemblies. His work on
this project included design of microelectronic assemblies for use in the GPS receive path. For further information on
