Who Are the Frequent Users of GPS Antennas?

For global positioning systems to serve their designed purpose,  they need to receive signals. These signals may only come from the artificial satellites that are hovering above us in outer space. Right now there are an awful lot of artificial satellites that are roaming the world from above the atmosphere. Without GPS antennas, the modern electronic devices that we have that come with GPS functionality are rendered useless because they will not work at all.

If you have a device with GPS functionality and are wondering why there are no visible signs or indications of an antenna, it is because they are built-in right inside your gizmo.  But many GPS devices come or can work even better with the use of an external antenna. You might be under the impression that GPS antennas are unnecessary, but some situations will call for it.

Countless numbers of people out there are unaware that their devices have GPS functionality. If you belong to this immense number of people and have not come across any kind of setback about it in terms of signal strength or loss, or an accuracy issue perhaps — chances are high that there is no need for an external antenna.

One situation wherein you will find an external antenna for GPS extremely useful is when you are in uncharted territory and you are not very much familiar with the place. A GPS device should work and point out to you the right track to take. However, if you are in doubt of its accuracy, or you have had issues with it in the past due to signal loss, then the use of an external antenna would be extremely helpful here.

The situation described above points out two important things, the integrity of your GPS device’s internal antenna if it is working well and okay. Then the second thing is if there is any external obstruction surrounding it. Obstructions surrounding your GPS device will interfere with the signal and thus disrupt the work of your GPS unit.

Other situations that will call for the use of an external antenna would be when you need to make a  switch, first from a GPS unit, and then transition towards an in-dash unit. Or if your GPS unit is just a new acquisition you have. In this case, you need to do your homework, that is checking out your locale and see if anyone else with a GPS unit is also experiencing the same setback that you are having. If you affirm that everyone else is experiencing a certain level of accuracy issues on their GPS devices, then the use of an external antenna would be highly recommended instead.

Obstructions and Interference: The Impact They Have to GPS Reception

GPS devices that are designed to work optimally with the use of external antenna systems deliver their intended function by receiving signals coming from satellite networks that belonged to the Global Positioning System. With respect to the direction of satellites and signal strength,  your car’s GPS unit is empowered. Thus, it can easily make accurate calculations concerning its physical location with a minimal margin of error.

In the presence of obstruction between your car GPS system and the surrounding skies, it will have a hard time obtaining satellite signals. This kind of scenario is not good, it is going to work to the disadvantage of your GPS systems failing to operate or is likely going to have a degraded accuracy.

High rise urban buildings and other similar infrastructure can bring about this kind of effect. Did you know that even your car roofing system can sometimes serve as an obstruction to your GPS system, too? A car roofing system can become an obstruction, too, and thus get in the way of the satellite signal to your vehicle’s GPS unit.

If you want to lessen the possible negative impact that a perceived obstruction to your GPS unit will likely bring, you may want to take advantage of a GPS locator instead and have it on your car window.

For better understanding, here is an example. Considering the metal roofing system of some vehicles, they usually come with an RF shield, unlike ragtops. For those vehicles that have tinted windows, they usually contain tiny metallic particles and because of that can get in the way of the signal for GPS antenna’s use.

How to Decide Between Laser and Plasma Cutting Table?

Laser and plasma cutting tables make it easy for anyone concerned to come up with a CAD or CAM-designed creation of their required parts from a wide array of materials and metals. The million-dollar question here is which among these two is the right option for you? In the absence of relevant experience on either two types of equipment, it would be hard to tell.

PLASMA CNC CUTTING TABLES

The use of plasma cutting technology has been around since the early part of the 1970s up to the last quarter of the 1980s, although this technique was refined only in the last few decades. The early batch of plasma cutting systems was not at all very efficient. They usually left behind chips and scars on the metals and materials they cut. Hence, they can’t be a good option when it comes to precision applications.

Fortunately, nowadays the plasma cutting technology comes to us in its most refined form. This is the reason why it is now popularly used by countless numbers of companies and shops from around the globe. So far, this is among the best options there is when it comes to cutting conductive metals, typical of which are the aluminum and stainless steel.

For your immediate reference, we have summarized below the key advantages and benefits of using plasma cutting table

Pros:

  1. Fastest production rate

This material cutting technology is highly reputed for its ultra-fast production rate, most especially when you are working with considerably thicker materials. This one factor can indeed slow you down when you’re using laser cutters.

     2.  Lowest operating cost

Plasma cutting technology is a practical option for cutting and processing your requirement materials since it consumes less amount of energy as opposed to laser cutting. This translates to lower operating costs for plasma cutting.

    3.  Capable of cutting through extremely thick materials.

Unlike laser cutting machines, plasma cutters won’t have a hard time getting and cutting through really thick materials, even if they are several inches thick.

    4.  Ease of Use

This option for your material cutting requires only marginal training, which makes them user-friendly.

    5. Multi-tasking

Contrary to the general impression of many people in the industry, plasma cutting systems are not at all confined to just cutting tasks alone. You can have them as gauges, they can perfectly line up your material.

   6. Safety concerns

This alternative cutting application is making use of a gas that is not at all highly flammable. In the process, it takes away a number of safety hazards that normally go alongside gas cutting procedures.

   7. Keeps Materials Cool 

Although it is operating at high temperatures, plasma cutting applications are reputed to keep the surface of subject materials cool. This works to the advantage of the material you are trying to cut since it lowers the possibility of warping, melting, or damage to the paint.

What is Right for Your Type of Business? 

A business that will be working on a high-volume project will find the use of plasma cutting tables beneficial to their goals. If they are involved in creating parts and materials out of thick metals that are highly-conductive, this material cutting application certainly is the right choice to make.

Nevertheless, if precision and versatility is a major consideration in your projects, the use of a laser cutting table will deliver you instead of the best option. Consider taking on a comparative analysis between these two major material cutting applications, it’s the only way you can figure out which among the two would be best suited to your needs.
