Today the term “GPS” is more and more often encountered. In today’s world, you can navigate the terrain not only with the help of a compass or stars, but also thanks to the satellites. The term GPS-satellite navigation system, which provides a distance measurement, denotes a global positioning system (English Global Positioning System – global positioning system). It includes 24 satellites that move around their planet in their orbits.
These devices are powered by solar panels and have a service life of about 10 years. They form the whole network, which is provided for free use for civilians. Today, a lot of devices are created that perform satellite navigation. In addition, it is possible to monitor the vehicle with GPS, to know its exact coordinates at the current time.
That’s just the buyer faces a difficult choice: to take an expensive device or Chinese, which navigator can be considered good? Some are generally held captive by allegations, considering this invention useless, relying on “more accurate” traditional atlases. It’s time to sort out the many myths about satellite navigation and devices that help to implement it.
It is enough for the receiver to communicate with two satellites.
Indeed, at least two satellites should be seen for the device for obtaining coordinates. This method of determining the position is called “two-dimensional fixation.” With its help you can find out your latitude and longitude. But the connection with the four satellites and more will allow to detail the information. The device begins to show also the speed of moving the object, its height above sea level.
GPS-navigators are in fact useless, they are easily replaced by conventional maps.
This statement has its own logic. Indeed, at one time people lived completely without computers, cars, planes and satellites. Simply GPS-navigation has become the next degree of evolution of technology. You can do without such a device, you just have to spend a lot of time to determine the right country, city, street and house. Then again to this point it is necessary to lay a rational route, which will take considerable time. But the GPS-navigator will need only a few minutes for this. At the same time the device will be able to take into account such nuances as detour of toll roads, choice of highways, etc. No special skills are required for this. But to work with conventional maps a person will need more than one book. You will need a road map of the country, region or city. Routing the route manually can be delayed by the clock, because you will also need a final adjustment. It is necessary to understand that it is possible to get into a strange city by passing through, so that cards can not be trivial at hand. And how much gasoline and nerves will it cost to return to the right route? But a complete set of world maps from the famous manufacturer of IGO will take about 8 gigabytes, which easily fit on a carrier with an area of less than a square centimeter. Paper same version of such a volume of cards in the car does not even fit. So you can compare the navigator to a regular card, as well as a computer with a typewriter.
In the navigator, the main thing is “correct” cards.
Often attention is paid to the fact that the maps and their manufacturer are important in the navigator. But the chip, the processor and the memory go into the background. In fact, the situation is correct almost exactly the opposite. When choosing a computer, it’s silly to focus only on the installed operating system and programs. Put here you can any “software”, but replacement parts can eventually become a problem. A similar situation with the navigator. But if computer parts are easy to purchase, then with satellite navigation devices it’s not so simple. There is usually nothing but the chip itself, battery, display and memory. It is on them and should pay close attention when choosing a navigator.After purchase, they will hardly improve, unlike the card recorded on the carrier. In addition, modern devices often operate on the basis of Windows or Android operating systems. This allows you to install not just different maps, but also entire navigation systems with their packages. And believing in this myth and saving, it turns out that the navigator, even with a good card, will just work slowly and have a bad screen.
Almost all navigators are manufactured in China, so there is no fundamental difference which device to buy.
In fact, this statement is erroneous. Sometimes you really should not believe the stickers that guarantee Korean, European or American production. Most often these products are still Chinese. And despite this, there is a wide gap between the individual models in quality, however, as in general for other electronics. In China, there are many factories that are differently equipped. The most modern have a conveyor, debugged technological processes, and there are also those where soldering is carried out “on the knee”, and manning – on the principle “just to work.” So it’s worth choosing the tested models with good reviews, even if you have to pay for it.
Navigator is best purchased directly from Chinese online stores.
The first disadvantage of this approach is immediately obvious – there is no guarantee. We’ll have to deal with an incomprehensible software product, and not the fact that in Russian. Yes, and in the event of a breakdown, you will have to spend time looking for a specialist who agrees to deal with the outlandish gadget. As a result, all these risks outweigh the insignificant savings. And the quality of such devices is usually such that breakdowns can follow one after another, which will make the device useless for long-term operation.
The best navigators are produced under the brand name “Pioneer”.
It is often said that these navigators are best suited to our realities, because they can install unlicensed navigation packages. In fact, these navigators “Pioneer” is about a dozen, they are equipped with the AVIC index. And to see really branded devices can be on the manufacturer’s website. But what is present in our market under the guise of the products of this venerable brand, can sometimes be explained by the sellers themselves. It is believed that on our expanses on sale there are about a hundred different “pioneers”. The market was swept by a wave of fakes and wishing to join it, earning on it. So what is the quality of the brand in these conditions? Most often it is not known exactly where such navigators are manufactured, which components are used, whether there is quality control. Under the same name, there are different models made at different plants and using different element bases. Therefore, if you look for the corporate quality of “Pioneer”, then you should pay attention to the AVIC series. And to forge this brand have become due to the fame, sonority of the brand. And in Ukraine, for example, this product is not officially supplied.
Navigators need voice announcements.
This myth can frighten those who do not understand these devices. In fact, this function is not the device itself, but the program installed in it. In order for the voice navigator to report on the turn or direction of movement, it is necessary that he simply had a speaker. The notification function is needed to notify the driver about the features of the route. In fairness, it should be noted that it is available in almost all modern navigation programs.
Navigators communicate with US satellites.
In fact, it’s worth noting that the device is a regular receiver. He can only receive signals, there is no talk of radiation here.
If you use GPS, then Americans will be able to track the location.
The radiation from the navigator is as small as from a flashlight or a camera. Accordingly, it is practically impossible to track it.
Navigators lie, they do not have all the paths.
Any navigator can usually give out only the current position coordinates – latitude, longitude and altitude. The rest falls on the shoulders of the software itself, loaded into this device. And if on an electronic map there is not that small brook, a path or even a road, then this question is not to the device itself, but to its program. And do not think that it will somehow be able to download the map from the satellite, as some think.
Touch screens in navigators are uncomfortable.
It should be understood that convenience is a subjective factor. Many users believe that with the advent of touch, and even capacitive screens in such devices, they have become much better managed. Increased the speed of work in the menu – just click your finger on the desired item, rather than choose it with the keys. However, with reliability not all so is simple. A broken sensor automatically makes the device dead. The button device breaks even less often.
GLONASS is better than GPS.
Speaking objectively, in the Russian GLONASS grouping the number of satellites is half that of the American analogue. In addition, Clinton disappeared artificially introduced interference in the civil GPS range, which made the determination of coordinates more accurate. True, modern devices can work simultaneously with both systems, which will only go for accuracy.
It is better to choose a specialized navigator.
It’s no secret that today almost all smartphones, and many tablets are equipped with a GPS chip. But how justified is their work as a navigator or is it better to trust highly specialized devices, especially for this and intended? When smartphones were with a diagonal screen of 2.8-3.5 inches, they clearly lost in the convenience of using 5-7 inch navigators. However, today the mobile device market has changed. The size of smartphones has grown, there are models from 5, and even with a 6-inch screen. Yes, and the tablets have displays ranging from 7 to 12 inches. The former gain in screen sizes disappeared. True, it is worthwhile to understand that GPS work in a phone or tablet is usually more energy-intensive. Wherever a normal navigator will live a day, a smartphone will only be able to help a couple of hours. But if you use the device in a car, and not when walking, a special charge will help. Today, emphasis is placed on the universality of gadgets. Smartphones can not only call, but also substitute for themselves navigators, readers, tablets and cameras. So highly specialized navigators have practically lost their trump cards.
