In the wake of personal navigation devices' success, cellular carriers have started to offer on-board and off-board navigation solutions, as well as a range of LBS (Location Based Services) such as friend finder and local search on GPS handsets.

Community and social-networking-related functionality, such as the sharing of POIs (Points of Interest) and geo-tagged pictures, is also becoming popular and is expected to boost GPS-enabled handset uptake as carriers, handsets manufacturers, and service providers look to capitalize on the LBS trend.

"While most CDMA handsets are already GPS-enabled and GPS is set to become a standard feature in GSM smartphones, GSM feature phones are next on the agenda to be equipped with GPS technology," says ABI Research principal analyst Dominique Bonte.

"GPS chipset vendors increasingly target handsets, looking for new markets and spurred on by the recent dramatic growth of personal navigation devices."

However, as GPS begins to penetrate lower-end phones, the cost, power consumption, and footprint of GPS chipsets will have to be further reduced. This will be made possible by single chipset technology and the emergence in 2009 of combination chips integrating GPS, Bluetooth, and Wi-Fi all on one die.

Major silicon vendors such as Broadcom, NXP, and Atheros are well positioned to develop such solutions following the acquisition of GPS chipset vendors Global Locate, GloNav, and u-Nav, respectively.

At the same time, the thorny issue of indoor GPS coverage has to be addressed, since handset-based LBS services are frequently used in challenging environments with reduced GPS signal strength. Network-assisted A-GPS and high-sensitivity GPS-receivers are becoming key requirements to reduce the time necessary to acquire fixes and to improve location accuracy.

What It Is and How It Works - For the uninitiated, GPS stands for Global Positioning System. It's a method of finding a receiver anywhere on earth or in orbit, and it's probably one of the most important inventions of the 20th century. GPS can be used in so many varied ways that new technologies are constantly being developed and improved in order to take advantage of it. Now why is GPS so important and useful? First, we have to understand how it works.
In order to work, a satellite network orbiting the earth is used. These satellites each broadcast a specific signal, which is received by inexpensive aerials and passed on to GPS devices where it is then decoded and used by dedicated software. The information garnered from these signals allows the GPS software to identify the satellite, its specific location, and even calculate the exact time it took for the signal to travel from the satellite to the receiver. Using different signals from different satellites, the GPS software can now analyze the position of the receiver, in terms of latitude and longitude.
Mapping It Out - Even getting the information about the receiver's location will be useless without something to compare it with. This is where the mapping comes in handy; thru this, GPS can analyze our location and maps out possible routes. Actually, the mapping data is what makes a GPS device expensive. This should be updated regularly and frequently in order to be accurate.
Several kinds of maps are created for different users. Road users need maps containing accurate data about the road systems in their particular region, but they won't need data about the lay of the land. Hikers, however, might require a more detailed map about the local terrain, water spots, and tracks or trails, but they won't need extensive information about the road systems. On the other hand, sailors will need specific data about the sea bed, navigable channels, and other related information that will allow them to navigate safely.
And what about fishermen? They also use marine GPS to keep track of the movements of fish in real time and to predict where they'll be the next day. In fact, cooperative fishing has become much easier with GPS, allowing boats to relay locations to each other while looking for the best fishing spots. There are also GPS devices called "fish finders", which combines GPS and sonar functions to track and store detailed fishing and maritime information.
Get Started with GPS - Consumers can avail of several GPS devices that are specifically designed for a variety of uses and functions. In-car systems have advanced features like voice guidance, dynamic route calculations, and even upgrading your maps from a CD-ROM. Rugged handheld GPS devices, like those from Garmin and Magellan, have a map inside and are usually used for outdoor activities. They do not have detailed road information and the user has to find his own way from point A to point B without any route calculations.
Recently, PDAs and even a few sophisticated mobile phones have incorporated GPS technology into their own systems. A GPS receiver can be easily attached to these devices, which makes them possibly the cheapest and easiest GPS receivers to use in the market today. Bluetooth technology has also started to make use of GPS, using a single PDA device wirelessly connected to several receivers.
