In the first place, what exactly is a GPS antenna? How does it work? GPS with antenna, these are modern tech devices that receive and amplify radio signals that are being transmitted by GPS satellites on specific frequencies. They are then converted and become an electronic signal to be used by a GPS receiver, which allows the device to make a precise computation of its location.
When you install an in-dash navigation receiver, it is somehow comparable to the installation of regular touch screen stereos, well at least for the most of it. But know that there are a handful of setbacks here, the reverse direction sensor and the antenna.
Proper Installation of GPS Antennas
When it comes to installing external GPS antennas equipped with in-dash navigation receivers, there are simple guiding rules you need to keep in mind. The first one here never attempt to modify the antenna in any way.
Even making cuts to it can lead to serious repercussions. Another thing to remember, you need to ensure it is always in perpetual contact with various GPS satellites that are in orbit to the earth. The best way to ensure this is to mount it in a position that will have minimal interference with its signal.
How Obstructions Affect Your GPS Reception
GPS navigation systems will only carry out their expected functions when they can receive needed signals coming from a web of global satellites that comprises the Global Positioning System.
By taking into account directions that is being indicated by multiple satellites, the GPS machine can make calculations of its physical geographic location. The margin of error here is very much alleviated.
One of the requisites for a GPS device to work optimally is a clear sky, completely void of any obstruction. Otherwise, it will have difficulty in grasping satellite signals. This happening can pave the way for it not to operate, or it will still function but with a much-degraded accuracy.
When GPS for car’s level of accuracy deteriorates, it can be due to surrounding structures such as surrounding tall buildings, or skyscrapers that are yonder your location or any other similar infrastructures. However, it must be remembered that car roofing systems can also serve as an obstruction to the strength of the GPS signal.
If surrounding obstructions are inevitable, there is one effective way to mitigate its effects and that can be done by placing your GPS antenna locator by your car window. But then again, there is a possibility that doing this in your own car may present you with some unique challenges as opposed to vehicles.
And there is no other way to determine this other than giving it a try. For example, metal roofs have a natural tendency to produce an even more intense RF shield when compared to ragtops. If your vehicle happens to have tinted windows, chances are high that they have tiny metal particles in them which can also cause some disruption to your GPS signal’s strength.
If the GPS with antenna you have fails on you when it is trying to obtain a signal, or if there are many observable occasions that it is giving you inaccurate and obviously unreliable data, then acquiring an external antenna is highly recommended. Usually, this measure will significantly help in fixing the problem.
