How GPS Can Be Used
Using the common cellular phone network, GPS is now widely used in tracking the location of all kinds of vehicle. The automatic vehicle
tracking system is a combination of GPS and Geographical Information System (GIS) that enables users both at personal as well as corporate level in tracking vehicle. The tracking devices attached in motor vehicle automatically update about location, speed, distance etc. Hence, time-by-time notification helps in fixing schedules thereby offering better fleet management.
Factors responsible for GPS signal errors
The GPS receiver requires the current time, the orbital position of the
satellite and a measurement of signal delay. Calculating accurate
co-ordinates of an object primarily depends on three data. To measure the
signal delay, the receiver prepares an identical sequence of the
Coarse-acquisition (C/A) code and compares it with the sequence received
from the satellite. The changes in bit transition can be calculated an
approx. of 10 nanoseconds for the code. As the signal travels at a speed
equal to the light, the net error can be taken as 3 meters.
GPS in Geocaching Games
Geocaching is an outdoor treasure haunting game that requires GPS receivers
in order to find out a cache. Geocachers search an undercover treasure by
using the co-ordinates of the cache through Internet and then go for finding
out the hideout place of the cache.

The quality of health is now one of the most concerned topics in all over
the world that advocates physical training. Today, there are numerous
technologies available in the market as far as physical training is
concerned. GPS heart rating monitor and GPS enable running watch is playing
an important role in making a daily schedule of exercise. These are
primarily useful for those who are desperate to come out from any serious
disease or surgery.
- GPS in Air navigation
Global Positioning System or GPS is now the
principal navigation system that provides location of any object on the
earth with accuracy. It is also used in shipping, automobile and other
industries for navigational purposes. As far as the aviation industry is
concerned GPS is used for both visual navigation and normal object guidance
when it becomes impossible for pilot to locate the destinations? position
due to bad weather or at night. Anyhow GPS assists the pilot in landing
airplanes at the exact location, as it requires maximum accuracy.
GPS is Different from ADF & VOR in Air Navigation
The principal aim of air navigation is for successfully piloting
the airplane without getting lost, breaking aircraft laws or endangering the
safety of the passenger. We know it?s really impossible to determine the
position of an aircraft at such a high speed and depends on their amount of
fuel for their safety. So it's important for the pilot to know the exact
location of the aircraft time by time. Aircrafts are generally navigated
under the Visual Flight Rules (VFR) and the Instrument Flight Rules (IFR).
In case of IFR, the pilots are permitted to navigate with the help of
instruments and other radio navigation devices. Where as in case of VFR
pilot moves forward by using direction, speed, time and distance of travel
along with visual observation.
services in mobile phones
For nearly a decade ago technology visionaries were talking about a
technology that people can use in their cell phones to get direction, track
their friends, keep an eye on any special object, kids tracking or simply
find the nearest hotel or hospital. Now finally those kinds of services are
finally starting with the help of Global Positioning System (GPS) that makes
our life simpler and smother.
of maps and compass after GPS
Maps and compass are two of the most essential equipments for
navigation. As far as finding yourself in from a particular point to another
or determining your exact location in a unfamiliar territory is concerned,
instead of the conventional maps and compass, the Global Positioning System
(GPS) is now playing a vital role. However, GPS alone can?t complete the
process of navigation and works with the help of these two equipments.
Here are some of the most common words that you will come
across while reading any article in any website related to GPS. These will
provide you basic idea of its functions and how GPS deals with these things.
and it?s Competitors
