Garmin GPS - nuvi 3700

Garmin - nuvi 3700

Garmin has established itself firmly in the world of portable GPS systems. Today most of the new cars released have employed Garmin for their navigation support. The company has GPS solutions right across the entire industry for Road, Water, and Air.

Global Positioning System (GPS) is a satellite based navigation system comprising of 24 satellites around our earth’s orbit commenced by the USA's Department of Defense (DOD). This service was initially employed strictly for Military purpose but from 1980, this has been broadened to civilian use too. The system works efficiently in any climatic conditions, time of day an any location with an unobstructed view of the sky. There are no subscription fees or any kind of set-up charges to use GPS.

The GPS satellites, orbit around the earth in a precise path and transmit their signal to earth. The GPS receivers use these emitted signals from the satellites and using a triangulation method calculate the GPS receiver’s exact position. The GPS receiver compares the time difference between the signals transmitted by the satellite and received by itself and draws a conclusion as to how far away is the satellite from the receiver and vice-versa.
With this technology the receiver can track itself with the help of other satellites too which are in orbital proximity with it to determine its actual position and get it displayed on the electronic map inbuilt in to the system. A GPS receiver must be locked in with three satellites at least to give the right 2D positioning, latitude, longitude, and tracking movement. With four or more satellite locked a 3D aspect can be granted to understand the position of a receiver on latitude, longitude, and altitude. Once the exact GPS location is known other aspects of physics can be easily calculated like trip distance, distance to destination and more.

The latest Garmin nuvi 3700 series has been my personal favorite for various technological and aesthetic aspects.
