Compact GNSS Optical Repeater Receiver – Single RF Output
The Compact GNSS Optical Repeater Receiver – Single RF Output creates one dedicated indoor GNSS re-radiation point from a remote fiber-fed signal source. At Global Foxcom we have designed this compact receiver to drive one compatible GNSS antenna, with variable RF gain for setting the required in-room signal level. The single-output architecture is suited to installations where one defined indoor area requires GNSS availability.

Designed around a one-to-one indoor transmit path, this receiver terminates the optical GNSS link close to the area where re-radiation is required. The recovered RF signal is routed through a single SMA output to one compatible GNSS antenna, creating a dedicated transmit point without introducing additional RF distribution branches. This configuration is appropriate for individual rooms, enclosed test spaces, or controlled areas where one antenna position provides the required GNSS re-radiation footprint.
The receiver combines optical transport with variable RF gain so the indoor signal level can be configured during commissioning without relocating the remote receive point. A fiber path of up to 6km provides physical separation between the signal acquisition location and the indoor antenna point, while the compact 208 × 138 × 50mm module can be positioned near the final RF connection. Compatible transmit antenna options are available through GNSS Antennas.

How does the Single RF Output receiver fit into a GNSS re-radiation system?
The receiver converts fiber-delivered GNSS signals back into RF and provides one output path for connection with a compatible GNSS transmit antenna. This configuration supports repeater installations designed around a single antenna coverage point.
What GNSS services and bands does this receiver support?
The receiver supports GPS L1/L2/L5, GLONASS G1/G2/G5, Galileo E1/E5a+b, and BeiDou B1/B2 signals received through the optical GNSS repeater architecture.
How does adjustable RF gain support indoor signal configuration?
The adjustable RF gain enables in-room signal level optimization by allowing the RF output level to be configured according to the installed repeater design and coverage requirements.
What fiber distance can be supported between the optical transmitter and receiver?
The receiver supports fiber links up to 6km with an optical budget of up to 3dB, depending on the optical link design.
Which antennas are compatible with this receiver?
The receiver is designed to drive Global Foxcom GNSS antennas for GNSS re-radiation applications. Compatible antenna options are available through the GNSS Antennas category.
What connectors are used for optical and RF integration?
The receiver uses FC-APC optical connectors for the fiber connection and SMA (F) RF output connector for connection to the transmit antenna path.
