The technologies are the pillars of our life. We are used to believe in computer systems, mobile services and different devices surrounding us. In some sense, we change our freedom for the opportunity not to leave our comfort zone. They say that laziness is the mother of invention, but also, it is a soft surrender at the mercy of e-God.
Hardly, the fact that he also works in a mysterious way will satisfy you when you will drive through the urban canyon full of cars standing in traffic jams. You should trust (in) your personal GPS e-God to be able to get to the office right in time. However, there are few cases when you shouldn’t do it.
Don’t believe the cheapest trackers
Cheapest is the dearest. Often we realize it too late. If you purchased a GPS tracker for 15 dollars on a Delhi public market, don’t expect it would work with the military accuracy. Different devices offer the variable precision from 3-5 meters to 2-3 blocks, which has nothing common with GPS accuracy.
No doubt it depends from GNSS chip model: on its quality and connectivity with the other systems like GLONASS and Galileo. It depends on A-GPS support of the signal as well, but the cheapest devices don’t have it.
Quite often the same GNSS modules used in different devices works with extremely different parameters. It is a blind spot of GPS device production. The manufacturer could save money on hardware details or firmware and the result would be poor even with an absolutely powerful GNSS chip.
Оn the other hand, buying a cheap device we need to know what part of this GPS tracker was “cut off” together with the price. If we talk only about some advanced fleet management options you don’t need, there is nothing wrong in the desire to save your own money. But some correlation between the price and accuracy of GNSS locator does exist.
Therefore, if you realize that your GPS tracker doesn’t work correctly in a countryside, the reason is more likely in your hands. Those times with the lack of satellites in the sky sunk into oblivion. No doubt, the GPS tracker should be equipped with a good hardware and software to lead you the right way.
Remember to update your mapping app
Basically getting the coordinates from GPS satellite might not be enough to solve the problems of local navigation. It’s not so informative to get a set of numbers when you try to find a particular cafe where you should meet with your partners. Mapping applications can relieve the life of a regular consumer.
Visualization of GPS technologies was the kick-start for whole navigation industry. Nowadays, mobile phone mapping applications lead people in their daily life.
Unfortunately, people are still too naive. Daily routine makes them forget to control surrounding electronic devices, including their own GPS tracker and mapping application that was installed in it. Sometimes, it causes tragic accidents.
The proof is the sorrow case on the Cline Bridge in Indiana in March. The car with a family couple was driven into a ramp of the disused bridge. The car driver just followed his GPS with the outdated map inside. The system had no information that the bridge had been demolished since 2009.
Often, while staring at the displays of navigation systems people missed warning signs that dotted the road. Unfortunately, not always GPS knows the shortest and most importantly the safest way.
Remember that “concrete jungle” are full of hidden dangers
GPS navigation in the urban area is always a challenge. Distortion and blocking of satellite signals make the precision of tracking much lower.
Assisted GPS and LBS supplementary technologies can solve this problem, but not every big city has good infrastructure to provide such support on the appropriate level. That’s why navigation in metropolitan area can easily become a nightmare.
To be honest, there is nothing to do with such a sad affair. In some sense, a tracker’s owner can use external GPS and GSM antennas to increase the sensitivity of the receiver and the right emplacement of the GPS tracker. The most suitable place is on (or under) the car roof where the signal strength is maximum. The poorest signal will be under the steering wheel and underneath the car.
Driving through a city downtown, we can’t be absolutely sure that our GPS tracker operates all its capacities 100 percent. Fortunately, supporting technologies do a really tangible work.
Global problems for the global world
Large-scale crashes of GNSS are extremely rare. And targeted hacking attack is also a very exotic case, but even US militaries acknowledge that their super protected brainchild GPS theoretically can be hacked.
According to YachtingMonthly.com, classes in celestial navigation have been reinstated at the Naval Academy in Annapolis, after approximately 20 years since this discipline has been suspended.
It doesn’t mean that we should also study celestial navigation. But theoretically any GNSS can be damaged by a courier external action.
No one is safe from unexpected accidents
Nevertheless, the main reason getting the wrong way is our own inattention or just a coincidence. As in the sad accident on the Cline Bridge, recently one Brazilian woman was shot dead by robbers when she came favela area instead of tourist beach place leading her GPS tracking app Waze. She and her husband choose the address on Rua Quintino Bocaiuva instead of Avenida Quintino Bocaiuva. Unfortunately, it was the fatal coincidence for that family. There is no GPS guilty in that case, but anyway media linked it with the problem of GPS confidence.
In this world, we are so unprotected and devices like GPS trackers help us to build the shield and avoid some nasty and even dangerous situations. But, as we like to state, GPS can’t substitute the heads on our shoulders.
