Portable single GPS timing over Fiber

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. 

The L signals are different frequency bands used by the GPS (Global Positioning System) satellites to transmit signals to GPS receivers. These frequencies are part of the evolution of GPS technology, providing higher accuracy, better reliability, and more advanced features, especially with the modernization of GPS.

Here are the key L bands for GPS and their corresponding frequencies:

1. L1

• Frequency: 1575.42 MHz
• Description: The L1 frequency is the most commonly used frequency for civilian GPS receivers. It carries the C/A (Coarse/Acquisition) code and the P(Y) code (for military use).

2. L2

• Frequency: 1227.60 MHz
• Description: L2 is mainly used for military applications but can also be used for civilian applications, particularly in high-accuracy GNSS systems with dual-frequency receivers. It carries the P(Y) code and the L2C code for civilian use.

3. L3

• Frequency: 1381.05 MHz
• Description: L3 is used primarily for nuclear detonation detection and is not used for standard GPS navigation.

4. L4

• Frequency: 1379.913 MHz
• Description: L4 is used primarily for the ionospheric calibration and research purposes. It is part of the GPS III modernization but has not yet been widely used for navigation.

5. L5

• Frequency: 1176.45 MHz
• Description: L5 is a high-precision, safety-of-life signal for both civilian and professional applications. It offers improved accuracy and is used for critical applications such as aviation. L5 is a new signal available from GPS III satellites.

6. L6

• Frequency: 1278.75 MHz
• Description: L6 is used primarily for commercial purposes and is part of the GPS III modernization. This signal is intended for high-accuracy applications and is used by the GPS III satellites to provide improved performance.

7. L7

• Frequency: 1267.6 MHz
• Description: L7 is part of the GPS III modernization program and is intended for both military and civilian use, contributing to a more robust and accurate GPS system.

Summary of GPS L Bands and Corresponding Frequencies:

These frequencies ensure that GPS signals can be used effectively in various applications, from consumer navigation to precise scientific and military purposes. The modernized signals like L5, L6, and L7 are designed to offer enhanced performance in terms of accuracy, reliability, and resistance to interference.
