GPS – Now can be used indoors
GPS or simply Global Positioning System has become the most wanted device in this 22nd century. Its origin takes us back to World War II where the use was limited to only military purposes. Within 50 years of its invention, people have made it a part of everyday life. Whether you are shopping, driving or even trekking, GPS system has shown its excellence in being a perfect guide. Scientists are always trying to discover the new useful directions in this field of GPS making us more software dependent. Indoor GPS is one of those useful directions just previously mentioned. Looking at its advantages we can’t even stop ourselves from being a GPS savvy. So let us foster on the features and its advantages for a better conclusion.
One of the advantages of using GPS indoors is that tracking can be done indoors too. These are especially required for the crime investigation. You can even keep a watch on your child while you are in office. Now days, ragging are a menace in various colleges and universities. GPS helps to observe the movements in and around the college campus.
Previously GPS signaling was not powerful enough to transmit weak radio frequency indoors. But with the technology advancement like Re-radiating it is now functioning even indoors. Re-radiating is a phenomenon in which the received signals are re-amplified and then sent to its receivers of GPS. This genuinely enhances the broadcasting capacity of transmission.
These days’ indoor GPS devices are available in mobile phones. This has given great potential to the common man. The Wi-Fi systems like Skyhook are software which helps to locate any indoor location. You can also accelerate the signaling potential by integrating MEMS chipset in your handsets. People can access to various unknown places with appropriate directions. The apps available with GPS service gives correct guidance to new enthusiastic trekkers who are ready to go beyond the limits. The mobile GPS device gives boost to the tourism industry as tourists come up with names of local places which definitely create new tourist spots.
Knowing its advantages, following lines will give you an idea about increasing the potential of your GPS device. As we know, the atomic frequency standards are used by GPS receiver for obtaining transmitting signals to determine exact location of the desired place. The oscillators which are made of quartz crystal improve the signal quality of these GPS signal. They are used in this device making available at a much lower price thereby installed in every mobile set. Hence the Life Cycle Cost also reduces to a greater extent. Signal Processing and the SNR (signal-to-noise) ratio is improved day by day so that GPS can work efficiently in those remote areas of this globe. The main challenge for Indoor GPS was high attenuation of the receiving signals which now has been solved successfully.
