Ce este Gps ?
Sunt convins ca de multe ori am auzit dar de putine ori ne-am intrebat ce este acest “gps” cu adevarat ?!!
Il folosim atunci cand conducem ,altii mai nou il folosesc pentru a-si monitoriza flota sau firma pe care o conduc,persoanele dragi sau animalele de companie ..incetul cu incetul acest sistem devine o foarte importanta componenta a vietii desi exista foarte multi care contesta avantajele acestui sistem…Nu voi intra in teoriile care exista referitor la acest sistem deoarece doresc ca prin posturile pe care le voi scrie sa scot in evidenta avantajele semnificative pe care aceast “gps” le are si pe care implicit le aduce persoanei sau companiei care il foloseste !
Voi incerca sa vin mereu cu noutati pentru cei interesati documentandu-ma de pe siteurile de profil din SUA si incercand impreuna cu cititorii sa scoatem in evidenta ce este bun si ce este poate mai putin bun in aceste sisteme ..
Astazi voi posta un mic textulet pentru a incerca sa intelegem cu adevarat ce reprezinta acest sistem..

GPS isi are denumirea de la Global Positioning System .Este cunoscut si sub denumirea de NAVSTAR (termen militar) si care inseamna un sistem de poziţionare globală.
GPS isi are denumirea de la Global Positioning System .Este cunoscut si sub denumirea de NAVSTAR (termen militar) si care inseamna un sistem de poziţionare globală.Acest program este dezvoltat de catre Departamentul de Apărare din Satele Unite ale Americii si permite aflarea poziţiei unui obiect/persoana pe suprafaţa pământului cu condiţia ca acesta să fie echipat cu acest sistem GPS.
Principiul de funcţionare al GPS-ului este acela de a folosi sateliţii în spaţiu ca puncte de referinţă pentru localizarea la sol. Printr-o măsurare foarte exactă a distanţei în linie dreaptă dintre receptor şi cel puţin 4 sateliţi se poate determina poziţia oricărui punct de pe Pământ (latitudine, longitudine, altitudine). În mod normal pentru determinarea poziţiei în 3D a unui punct de pe suprafaţa terestră cu ajutorul poziţiei sateliţilor este nevoie de doar trei distanţe (trei sateliţi), deoarece metoda care se utilizează este cea a triangulaţiei. A patra distanţă se determină pentru minimizarea erorilor de poziţionare, datorate ceasurilor din receptoare care, nefiind atomice ca cele din sateliţi, nu sunt extrem de exacte. Distanţa dintre satelit şi receptor se calculează prin cronometrarea timpului de care are nevoie semnalul radio să ajungă de la satelit la receptor. Fiecare satelit are semnalul propriu (Pseudo Random Code) astfel încăt receptorul va şti exact despre ce satelit este vorba. “-detalii complete pe wikipedia !

I rarely get lost, have no trouble reading maps, but using the Garmin nuvi 265WT is sure a lot easier, especially when traveling alone. I can’t compare it with other navigators, but I found it generally easy to use, and though the first look at it seemed rather complicated, I found I needed to check the manual (online, not with the product) only once or twice to pretty much figure out everything.
The maps are key features in a navigator, of course, but I found the decisions the nuvi made were often better than my own decisions would have been. Tested it in my own “backyard” and it took me on some routes I wouldn’t have, but which I should have, chosen. In other cases, it picked some of my favorite tricky shortcut routes that I thought it would never find. Most interesting was the time I asked it to return home by the most economical way, and it twisted and turned until we were on rarely used dirt roads throug the woods. Exciting in its way, but a bit scary if it had been at night or in unknown territory.
On another trip from a hotel to the Mt. Vernon Inn in Virginia, it took busy streets and highways to the Inn, but the return route was a beautiful route along the Potomac River. Perhaps it was because I asked it to stop at a Dunkin Donuts on the way back, though.
There were two problems I noted with it. I was taking a trip from Massachusetts to Maryland one sunny day, and the nuvi was on the dash, in the sun all day. It apparently was overheating, even though the AC was on and the outdoor temperatures weren’t too high. While it continued to navigate with no problem, it responded very slowly to any menu selections, taking minutes in some cases before the screen changed. The manual warns against leaving it on the dash of a parked car, which makes sense, but it shouldn’t exhibit a problem when you’re using it in a moving car.
The second problem occurred when traveling back from the Mt. Vernon Inn that I mentioned above. I asked it to find and go by a Dunkin Donuts on the route back, but we would have gone by the DD if the passengers didn’t happen to spot it. When we left the DD, the nuvi had us go around the block and come back to it, this time letting us know that we had arrived–and it would have had us do it again, apparently, as it seemed to get into a loop. I had to stop the trip and re-set the destination.
Generally, though, it was great to have, giving me a wonderful degree of freedom to “take the road less traveled” when I was in somewhat unfamiliar territory, confident that any side-trips would end without being lost.

It’s not complex to make decisions when you know what your values are.
To be a good human being is to procure a amiable of openness to the far-out, an gift to trusteeship aleatory things beyond your own control, that can take you to be shattered in hugely exceptionally circumstances for which you were not to blame. That says something very important thither the fettle of the ethical passion: that it is based on a conviction in the up in the air and on a willingness to be exposed; it’s based on being more like a weed than like a jewel, something fairly tenuous, but whose acutely precise attractiveness is inseparable from that fragility.
Wow! That was a really great article. Please keep writing because I love your style.
