To provide reception of GPS/GLONASS/GALILEO positioning signals inside aeronautical hangars, integration facilities and other buildings, ELTA developed a repeater system (R3G) used to distribute, from a rooftop antenna outside, these signals onto the desired area. 

R3G: A universal positioning signal repeater:
GALILEO/GPS/GLONASS (E5A-E5B-L5-L3),
GPS (L2),
GLONASS (L2),
GALILEO (E6),
GALILEO/GPS/GLONASS (E2-L1-E1).

R3G: A complete system:
Outside receiving antenna with its attaching mast,
Filtering and amplification radiofrequency unit,
Re-transmission antenna unit,
Link and interconnection cables.
