Descripción

Individual portátil GPS de tiempo largo de la Fibra

El Thor de Fibra portátil F-1GPS-TX/RX se dispone de sistemas de apoyo a la remota ubicación de industrial antenas de GPS. Estos kits son ensamblados y ajustados a los requerimientos únicos de cada aplicación. Thor GPS a través de los sistemas de fibra son una excelente solución para la limitación de la distancia entre el transporte marítimo o de gobierno antenas de GPS y radio receptor de la se?al del equipo. En general, cualquier equipo del sensor o ajuste de hardware, tales como tiempo universal o receptores GPS de navegación de engranajes deben estar instalados y ubicados dentro de los 100 pies de la antena. La mayoría de los industriales modernos tipo de sistemas requieren antenas con una vista clara del horizonte para que funcione correctamente. En el caso de los grandes transatlánticos, subterráneo, instalaciones militares, o los grandes edificios o estructuras(metrópolis); puede ser un desafío para instalar equipos GPS dentro de 100 pies de una adecuada ubicación de la antena. Thor resuelve este problema mediante la ampliación de la distancia a más de 20 km por la conversión de la se?al de GPS de la antena y del cable coaxial cable de fibra óptica. F-sistemas de GPS están disponibles en una variedad de factores de forma, y puede ser personalizado atentos a usuarios individuales de las aplicaciones.

GPS de referencia de se?ales de temporización son ampliamente utilizados para sincronizar estaciones base celulares.

GPS sistemas normalmente consisten en un activo de la antena, un receptor GPS y una longitud de cable coaxial para conectar con ellos. Desafíos comunes que surgen cuando la distancia entre la antena y la estación base celular equipo (normalmente en el sótano) es mayor de 300 ft. El cable Coaxial se ejecuta más de 300 pies no son prácticos para la mayoría de receptor GPS de los sistemas, por lo que un enlace de fibra óptica es necesario en esas distancias, y Thor los enlaces de Fibra óptica son algunos de los más confiables, rentables vínculos en la industria.

Question and Answers

Question:
It looks like the fiber used is Single Mode but need to confirm this?

Answer:
Yes our GPS over Fiber units all use Singlemode fiber; they do not work on Mulitmode. We have multiple options for the GPS units. As well as having a multi channel unit up to 4 GPS inputs. All of these units will only work on Singlemode Fiber only.

Question:

I want to confirm whether this will work with a Trimble Thunderbolt E GPS Disciplined Clock Starter Kit (62989-50).

Answer:

There is no reason why it shouldn't, our units are wideband and
totally transparent. v

Question:

What is the GPS frequencies, and how to send GPS it over fiber

Answer:

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

Question:

Attached is the GPS antenna that will be utilized in out system.

This GPS antenna is what we will need your equipment to interface with. This drawing is crude, but how we plan to use:

Overall Diagram

Figure 4: Overall Example Usage

I am also attaching the GPS antenna that we are using.

Will this work for what we are attempting to do?

INNOVATIVE DESIGN WITH MULTIPLE PATENTS
The VEXXIS GNSS-800 series antennas feature a patented multi-point feeding
network and radiation pattern optimization technology. In additional to having
enhanced performance in multipath environments, the GNSS-850 antenna is able
to maintain a low profile while achieving both high peak zenith gain and low gain
roll-off from zenith to horizon, without sacrificing tracking performance. This new
technology significantly enhances the low elevation angle tracking capabilities,
extending operation to the entire GNSS constellation. Furthermore, the antenna is able
to achieve greater phase center stability through our innovative element design. This
directly translates into improved carrier phase measurement and a better RTK solution.
TRACKING IN CHALLENGING ENVIRONMENTS
The ability to track low elevation satellites while maintaining a high gain for higher
elevation satellites makes the GNSS-850 an excellent choice for any applications
where the sky is partially visible, such as operating close to tree lines, under foliage,
or in urban canyons. The antenna is able to track any visible satellites from horizon
to zenith, providing maximum number of observations for an enhanced positioning
solution.
NOVATEL’S TOUGHEST PRECISION ANTENNA
GNSS-800 antennas are the toughest high precision antennas NovAtel has designed
to date, ensuring their survivability even in the harshest operating environments. The
antennas feature ultra-durable watertight enclosures, and have been proven to sustain
intense vibration, earning the MIL-STD-810G rating.

Answer:

If your signal is GPS, please consider F-GPS-TX/RX, not the L-Band TX/RX.

GPS operates at a very low RF level and requires a 50-ohm termination

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.

Question:

We need to install a Cobham Explorer 710 BGAN satellite terminal in an overseas mission that has more than 500 feet between the antenna and the transceiver.

We will need to use a single mode fiber to achieve this distance compared to the LMR400 – 50 Ohms Coax.

We will need Coax to Fiber Media converters capable of supporting both transmission and reception in L-Band frequencies.

I have attached a diagram with our potential layout.

The devices in yellow field below are just a representation of our Fiber Media requirements that we seek from vendors

Question:

Thanks for the quick response. We wouldn’t need anything bidirectional – just need to repeat the GPS signal from outside into the building. Should match close to the below diagram. These cell boosters have a silly requirement to have a GPS antenna attached, which in my opinion defeats the purpose of installing them deep inside buildings where cell signals don’t penetrate. That’s where I believe your product might come in handy. The fiber optic coupler shown below (F-PLC-1x4) is a passive device correct? How many can we go before the signal gets attenuated too much? Is the GPS Out port intended to go directly into the GPS input of another device or an antenna?

Answer:

Yes, the fiber optic coupler shown (F-PLC-1x4) is a passive device.

Our standard 1?mW TX can be split up to 4 times. We also offer a 10?mW TX that can be split up to 16 times, depending on your setup.

Regarding your question about the GPS OUT port: yes, the RF output has unity gain relative to the RF input from the antenna. It is intended to connect directly to the GPS input of your equipment (not to another antenna).

How many endpoints are you looking to support?
If you require multiple endpoints, there are two recommended configurations:

Multiple 1?mW TX units with individual 1x4 splitters – This setup provides redundancy and flexibility.
A single 10?mW TX with a 1x16 optical splitter – This is more centralized and efficient for higher endpoint counts.

Question:

I need to replace a coax run in my building with fiber for LTE cellular frequencies. I was looking at your L-band over fiber Tx+Rx Basic 1 channel kit. The fiber run would be short, probably a max of 600ft.

We purchased the transmitter and receiver listed below to install a weBoost Office 100 cell signal booster. Our goal was to extend the distance between the outdoor antenna and the indoor antenna using the equipment we purchased from you; however, this setup did not work as expected.

I spoke with someone last week regarding this issue, and they advised me to send an email with detailed information so that you could review our setup and recommend suitable products.

Please let me know if you have any other products that would work for this type of configuration, or if you have any recommendations to achieve the desired distance extension.

Thank you for your assistance.

Answer:

Here is the link to the 75Ω L-Band over Fiber TX/RX kit:
https://thorbroadcast.com/product/l-band-over-fiber-tx-rx-basic-1-ch-kit.html

Here is the link to the 50Ω GPS over Fiber TX/RX kit (both can cover cellular frequencies):
https://thorbroadcast.com/product/1-gps-fiber-transport-system.html

However, these are unidirectional transmitter/receiver sets. For cellular applications, you would typically need two sets, along with an RF circulator or (even better) a diplexer.

Hopefully that makes sense — we have had clients use this solution for Cellular over Fiber, and it works great as long as your RF spectrum stays within the supported frequency range
