| What is GPS? |
| GPS stands for Global Positioning System, a radio-navigation system made up of three key elements. First, satellites placed in orbit around the globe. Second, ground stations to control and maintain satellites in terms of orbital position and operation and the integrity of signals they produce. And last, GPS receivers which gather broad casted data from network of satellite and convert it into useful information, usually your precise geographic location.

| How does GPS Work? |
| Satellite, 12000 miles above surface of Earth, transmits a constant stream of encoded data. This data contains information about the location of the satellite along with a highly accurate time code. GPS receiver builds up an internal map of the precise location of up to 12 satellites. Through applying a mathematical formula to the data received from each satellite, GPS receiver can calculate.Its exact distance to each satellite. Once receiver's distance from several satellites is established, a process similar to triangulation measures the distance from at least three satellites and determine an exact the exact location on the globe. Using this information, it is also possible to calculate altitude, speed and direction. Combining this information with a mapping application location running on a computer then make it possible to see an exact location in real time onto a map of the surrounding area.

| How does GPS Work? |
| Accuracy of the GPS system can and will vary slightly. For 95% of the time, your SekurTrack™ are accurate. As long as the GPS receiver has a clear view of the sky, it will work anywhere on Earth, accurately reporting your current latitude, longitude, heading and speed.

| How long does it take to calculate your location with a GPS?
|
| Calculation of a position with GPS varies according to certain conditions. The first time out of the box, the Time To First Fix (TTFF) will be between 15 to 20 minutes, depending on the receiver and how far it has moved since its last known location. However, after that the receiver can reacquire the satellite signal and calculate a new location in just a couple of seconds when being reactivated

| What is GPRS and what does it Do?
|
| "GPRS" stands for General Packet Radio Service. Designed for delivering data faster and more reliably. This new low-cost service allows information to be sent and received across a GSM mobile telephone network. This service is for transmission of data only. GPRS provides a permanent connection where information can be sent or received immediately as the need arises, this is why GPRS users are sometimes referred to as being "always connected".
|
| |
| Why Use GPRS?
|
| GPRS is extremely useful if you need to
|
| (a) |
Send and receive small or large amounts of data, information or messages often,
|
| (b) |
Have that information available to you soon as you get it - instead of having to log on or query for it.
|
| |
| The GPRS tariff structure is based on a fixed cost, dependent on the quantity of data transmitted, not by the time of transmission. As a customer, you are able to fix your operating costs without the concerns of variable billing.

| What is SMS ?
|
| Short Message Service (SMS) is a telecommunications protocol that allows the sending of "short" (160 characters or less) text messages. It is available on most digital mobile phones and some personal digital assistants with onboard wireless telecommunications. The individual messages which are sent are called text messages, and more colloquially SMSes, texts, or even txts (in "text speak").
