Part Number: F-4GPS-TX-WE / F-4GPS-TX-RM
Thor Fiber F-GPS systems are available to support the remote location of industrial GPS antennas. These kits are assembled and tuned to the unique requirements of each application. Thor GPS over fiber systems are a solution for the distance limitation between maritime or government GPS antennas and radio signal receiver equipment. Typically any sensor equipment or tuning hardware such as universal time receivers or GPS navigation gear must be installed and located within 100 ft of the antenna system. Most modern industrial type systems require antennas with a clear view of the horizon to function properly. In the case of large ocean going vessels, underground military installations, or large buildings or structures; it can be a challenge to install GPS equipment within 100 ft of a suitable antenna location. Thor solves this problem by extending the distance to over 20 miles by converting the GPS signal from the antenna from coax to fiber optic cable. F-4GPS systems are available in a variety of form factors and can be custom tuned to individual users applications.

The F-GPSF GPS over fiber system is a transmitter and receiver pair used to transmit the RF Carrier signal from a GPS antenna to a remote location up to 10 Km. There are many advantages to converting the GPS Carrier to an optical signal for GPS over fiber. Fiber Optic cable is much less expensive than low loss coaxial cable used for RF signals. It is also much smaller and easier to work with. Optical signals are not affected by RF interference, therefore this system can be used to transport a GPS signal over fiber through a noisy RF environment. The F-GPSF can also be used to transport the GPS signal over fiber from a single GPS antenna to a multitude of locations throughout a building, aircraft, or ship.
This Fiber Optic GPS Antenna Link is a complete system which allows us to convert the GPS Carrier from RF to Light, transmit it up to 20 Kilometers if need be then reconvert it to RF to be received by the GPS Receiver.
Global positioning systems (GPS), used for navigation, relies on signals from satellites in a geosynchronous orbit around the earth. This synchronization is required for personal communications systems (PCS) such as cellular telephones. PCS base station signals using fiber optic transmitters and receivers experience low loss and high quality. In addition, smaller, less expensive power amplifiers can be mounted to the tower reducing transmission losses and system cost. Fiber’s dielectric properties also reduce damage from lightning strikes at PCS base stations. Fiber optic L-Band, GPS links can also be used as an outside repeater in shopping malls, tunnels, and subways where PCS signals are non-existent or extremely weak, allowing L-Band satellite transport.
IMPORTANT NOTE*** (it is very important to interface our unit with SC/APC - Angle Polished Connector to avoid any light reflections.
If your fiber is terminated with the SC, ST, FC /PC flat connector, you need to use an optical jumper from PC type to SC/APC for proper conversion.

I’m involved in the development of a Video Broadcast project. In this project, we
have to realize two different Broadcast facilities, each one with its
own GPS receiver and SPG Generator. Due to the logistic, GPS antenna
will be at least 1km away from the receiver. For this reason, I choose
to use a Thor System F-4GPS, to interface antenna through a Single-Mode F.O. System Now the point is: how can I be sure that the chosen
SPG and GPS antenna is compatible with Thor System? Yesterday someone
from your “chat” suggests to me to collect some technical data about
antenna and receiver and send all this information to
[email protected] This is the reason why I’m writing to you. So
the system is composed of a Leader SPG/GPS receiver LT4610 + a GPS
Antenna from Furuno Electric model 117A. Attached to you
will find some documents, including a raw schematics about the GPS and
SPG system Please can you check if there is a compatibility between
THOR System and the proposed Leader device? Thaks a lot for your help
I reviewed your drawing, antenna, and GPS LT4610 receiver
specifications. It is 100% compatible with our GPS fiber systems.
There are 2 important aspects you need to be aware of, you need to
have 4 single-mode fibers, the fiber needs to be terminated with
reflection proved connector SC/APC, or if it is not SC/APC, you would
need to use the conversion cable jumpers to interface our GPS
equipment.
Those units have enough power to serve about 10Km of fiber.
4x Ch L-Band DWDM Transmitter for Satellite TV. Designed for delivery of satellite service to more than 5000 locations, or to be used as a satellite to home LTTH system. Used similarly as many CATV FTTH systems, instead LTTH units transport 4 independent satellite signals off the Dish and mux them into a single fiber. DWDM light spectrum could be amplified by EDFA, this is why we can distribute the
4GHz Mini Analog RF over fiber transport equipment. Transmitter has SMA 50ohm electrical interface and accepts Analog RF signal up to 4000Mhz, units come standard with optical FC/APC output. The receiver accepts an optical signal from it's FC/APC port and converts it back to the electrical RF. These units are ideal for transporting high frequency RF over fiber where copper can not complete the application due to its inherent distance limitations.
