Frequently Asked Questions


The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. The system provides critical capabilities to military, civil and commercial users around the world. It is maintained by the United States government and is freely accessible to anyone with a GPS receiver. GPS works in any weather conditions, anywhere in the world, 24 hours a day. There are no subscription fees or setup charges to use GPS

The Global Positioning System (GPS) is a constellation of up to 32 satellites that orbit at a height of 26,600km above Earth. The satellites are owned by the US Department of Defense, but anyone can use the signals from those satellites, provided they have a receiver.

For the receiver to work, it needs to be able to “see” four of the satellites. When you turn on your receiver, it may take a minute or so to locate these satellite signals, then to download data from the satellite before positioning can commence.

Fundamentally, two things need to happen for this to work effectively:

1) The GPS receiver measures the distance from itself to a satellite by measuring the time a signal takes to travel that distance at the speed of light.

2) When the satellite’s position is known, the GPS receiver knows it must lie on a sphere that has the radius of this measured distance with the satellite at its centre. The receiver need only intersect three such spheres, as seen in the image below.

This process, known as trilateration, is an effective means of determining absolute or relative locations. But there’s a problem. Although the GPS satellites have very expensive atomic clocks on board - and therefore know what time their signals are transmitted - the GPS receiver has a very cheap clock. That means there is uncertainty about the “receive” time. So, instead of three satellites, the GPS receiver must receive four, so it can account for what’s known as the receiver clock drift.

No special hardware is needed to access the tracking data. You only need an internet enabled PC or Smartphone, to logon to the Tracalogic web-site use your unique username and password.

The accuracy of a position determined with GPS depends on the type of receiver. Mostly consumer GPS units have an accuracy of about +/-10m

The device has an internal battery which in case of disconnection from the main power source it can function for minimum three to four hours.
