The Thor Fiber portable F-1GPS-TX/RX 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 an excellent solution for 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(metropolis); 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 20km by converting the GPS signal from the antenna’s coax to fiber optic cable. F-GPS systems are available in a variety of form factors, and can be custom tuned to individual users applications.
GPS reference timing signals are widely used to synchronize cellular base stations.
GPS systems typically consist of an active rooftop antenna, a GPS receiver and a length of coaxial cable to connect them. Common challenges arise when the distance between the rooftop antenna and the cellular base station equipment (usually in the basement) is greater than 300 ft. Coaxial cable runs over 300 ft are not practical for most GPS receiver systems, so a fiber optic link is required at such distances, and Thor Fiber optic links are some of the most trusted, cost-effective links in the industry.
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.

GPS (Global Positioning System) is a satellite-based navigation system that allows users to determine their precise location, speed, and time anywhere on Earth. GPS signals are transmitted from a network of satellites orbiting the Earth, and can be received by GPS receivers on the ground or in aircraft, ships, and other vehicles.
GPS frequencies are within the L-band range of the radio frequency spectrum, specifically within the 1575.42 MHz frequency band. These signals are very weak, with an average power of just -160 dBm (decibel-milliwatts), and are susceptible to interference and signal loss over long distances.
To send GPS signals over fiber optic cables, a GPS modulator and a fiber optic transmitter are used. The GPS modulator converts the GPS signals into a format that can be transmitted over fiber optic cables, while the fiber optic transmitter sends the signals over the fiber optic cables to the desired location.
There are several types of fiber optic transmitters that can be used to send GPS signals over fiber, including both analog and digital transmitters. The choice of transmitter will depend on the specific requirements of the application, including the distance that the signal needs to be transmitted, the type of fiber optic cable being used, and the data rate of the signal.
It is also important to note that GPS signals are susceptible to interference and signal loss over long distances, so it may be necessary to use amplifiers or repeaters to boost the signal along the way. This is particularly important when transmitting GPS signals over long distances, as the signals can become degraded due to factors such as atmospheric conditions and other sources of interference.
In addition to being used for navigation and location-based services, GPS signals are also used in a wide range of applications, including surveying, mapping, timing, and scientific research. The ability to transmit GPS signals over fiber optic cables enables a wide range of possibilities for these applications, including the ability to transmit GPS signals to remote locations that may not be accessible by other means.
Fiber optic cables are a reliable and efficient means of transmitting GPS signals over long distances. They offer several advantages over traditional copper cables, including higher bandwidth, higher data rates, and immunity to electromagnetic interference. They are also more resistant to physical damage and are less susceptible to corrosion.
To transmit GPS signals over fiber optic cables, the signals must be converted into a format that is compatible with fiber optic transmission. This is typically done using a GPS modulator, which converts the GPS signals into an optical format that can be transmitted over fiber optic cables.
There are several types of GPS modulators available, including both analog and digital modulators. Analog modulators use continuous wave (CW) lasers to transmit the GPS signals, while digital modulators use pulse-code modulation (PCM) to transmit the signals in digital form. The choice of modulator will depend on the specific requirements of the application, including the distance that the signal needs to be transmitted and the data rate of the signal.
Once the GPS signals have been modulated, they can be transmitted over fiber optic cables using a fiber optic transmitter. There are several types of fiber optic transmitters available, including both analog and digital transmitters. The choice of transmitter will depend on the specific requirements of the application, including the distance that the signal needs to be transmitted, the type of fiber optic cable being used, and the data rate of the signal.
It is also important to note that GPS signals are susceptible to interference and signal loss over long distances, so it may be necessary to use amplifiers or repeaters to boost the signal along the way. This is particularly important when transmitting GPS signals over long distances, as the signals can become degraded due to factors such
Based on the specs of the antenna, it looks like it should work because we are directly modulating incoming RF signals into optical wavelength output. It should be really quick and easy to set up. Just make sure you have single-mode fiber and SC/APC connectors.
