A chip is a miniature electronic circuit manufactured on the surface of
semiconductor material. Terms such as integrated circuit (IC),
microcircuit, microchip, semiconductor chip, silicon chip are used
interchangeably with the term ‘chip’.
Chips are a fundamental to today’s electronic technologies and are
employed in military and aerospace applications, medical instruments,
consumer goods, automotive products, communications fields and of
course GPS technology.
GPS chips compare signals from several geo-positioning satellites to
determine position on the earth's surface. GPS is an acronym for
global positioning system. GPS refers to a system of satellites and
receivers that allow people and devices to pinpoint their precise
location on the earth. The system relies on 24 satellites that orbit
the earth twice per day. A GPS chip receives transmissions from a
few of the satellites and is able to discern very precise positioning
data.
Different approaches for building a GPS circuit are used in a GPS
receiver. A large number of components are surface mounted onto
a printed circuit board (PCB). Connection from the PCB to the display
unit is made using a flexible polymeric circuit board. Some parts of
the device require shielding from radio waves. Computation of the
receiver's location is achieved with an on-board processor. Since GPS
was declared fully operational in 1993, GPS chips have become a
vital global utility, indispensable for modern navigation on land, sea,
and air around the world, as well as an important tool for map-
making, and land surveying.
GPS chips consist of a GPS receiver chip and a GPS tracking chip. A
GPS receiver chip calculates current position (latitude, longitude,
elevation), and the precise time, using the process of trilateration
after measuring the distance to at least four satellites by comparing
the satellites' coded time signal transmissions. A GPS tracking chip
uses GPS to determine the location of a vehicle, person, or pet and
to record the position at regular intervals in order to create a track
file or log of activities. The track file or log is stored in a GPS data
logger from which it can be easily read anytime. GPS cellphone chips
are also being constantly developed for modern cellphones which
support GPS. A GPS chip manufacturer should always take note of
the resolution and accuracy needed by the customer before
manufacturing GPS chips. GPS chips are manufactured to meet most
industry specifications.
GPS chips are used in many applications. The application of the GPS
is very broad, and as the prices come down the number of uses are
increasing. Portable GPS devices are used by fisherman and hikers
to help them navigate in the wild. Many new cars are being
equipped with GPS systems to help drivers with navigation. The
military uses GPS to guide cruise missiles to pre-specified targets.
Today more and more cell phones are equipped with a GPS chip and
more and more phones allow you to use the GPS information. If the
GPS chip in the phone supports Assisted GPS (A-GPS) and the cell
phone carrier offers this service, the GPS reception will be superior
to all the above GPS solutions. The Time-to-first Fix (TTF, the time it
takes the receiver to calculate a valid GPS position after it has been
switched on) will be reduced to only a couple of seconds and it will
be able to capture GPS signals where others let you down. For
example in narrow streets with high buildings or in dense forests.
Anothe example of a GPS chip application is when a vehicle is stolen.
If a GPS chip is situated in the vehicle, using GIS and GPS technology
just by giving the GPS chip number the vehicle can be tracked in
seconds.
