GPS trackers

How they work: 

GPS trackers are usually attached to something or even somebody, in order to report their location when moving or at rest. They send out location reports at regular intervals when moving, sleep when not moving until movement is again detected. There are many possible reasons for their use with asset protection and personal safety being the most common.

The TrackServer App or Webapps let any number of people see where one or more trackers is, and has been. The login can contain 1 or 2 parts, the account reference and possibly a user-set password.  The reporting frequency is typically every 1-5 minutes.

Our trackers work almost anywhere. One recently made a journey from Mayo to Mongolia and back, with a continuous reported trail there and back, because our SIMs roam (free) in most coutries.

Our apps are simple to use, allowing normal people, not "Techies", to easily control them without the cost of a monitoring centre.  Our devices are fully legal / licensed to legally use Google maps.
Our trackers have valuable alerting options to detect and report: 

  1. when and if it moves (if armed to so report);
  2. if it goes over a certain speed;
  3. when it leaves or enters a particular place (zone);
  4. when its panic button, if any, is pressed;
  5. if its battery drops below a certain level.


Technical details:

A GPS tracker contains a GPS module, a modem; an accelerometer to detect motion, and a rechargeable battery. They are very similar to mobile phones. They come packaged in a plastic (ABS) cases whose size depends on its battery size and whether it contains a magnet. They vary greatly in size.
When near a window/opening, they should receive the radio signals from orbitting satellites 20,200km above Earth, from which they calculate their latitude and longtitude to 6 decimal places. The accuracy depends on many factors including: 1) the surroundings and the strength of the satelite signals; and 2) the reporting frequency. Weak signals and long time intervals between reports give reduced accuracy. The first location fix should be ignored as it is usually quite inaccurate. Wait for subsequent ones. Trackers will not work if surrounded by metal, or deep inside buildings, reinforced concrete walls or floors, trees, etc. The laws of Physics apply.
Position reports are sent via data packets to/through the mobile phone networks to a server database, which the TrackServer App and web-apps access. These are:

  1. - for large screen devices, such as a computer. It's a web page/web app for any browser;
  2. - for small screen devices (e.g. any phone) web page/app ( for any browser;
  3. The TrackServer App from the App Store or Play Store - needs to be downloaded;

Location Push:  Our devices are so-called "push" devices because they actively send out location data when on and moving, at given time intervals. Old technologies were "Pull" devices as one needed to text them to get them to reply with their location details. Older "Logger" devices need their data to be downloaded to a computer. Users can send commands from the App/WebApp to change the tracker's settings. When a tracker stops moving, it drops to a "heartbeat" report frequency of every 4 hrs.

Our Unique Selling Points (USPs):

  • allows tracking using any internet device;
  • long (1 year) look-back history;
  • panic button gives alert typically in under 1 minute;
  • alerts can be either SMS or email;
  • up to 3 geo-fences/zones available;
  • the degree of motion sensitivity can be adjusted over the air by us;
  • they work straight from their box - no need to purchase a SIM for it;
  • SIM cards roam across most of the world;
  • we provide 6 modes or operation that extend battery life from days to months.

Antennas: Each tracker has two antennas, one for communication (GPRS/GSM) and one for satellite signal reception (GPS). These are located on the front face (side with LEDs) of the tracker or on the side opposite any magnets. This MUST face the outside world. The App/WebApp displays the times of the last location report time/date and the Last Communication (GPRS) time/date.

Battery duration:  Our trackers contain Lithium Polymer (LiPo) batteries which have built-in under- and over-voltage protection, short circuit and high temperature cut-out for safety. If a tracker has been allowed to be flat for a very long time, it may take many hours / days to recharge.
Battery life depends on:

  1. the size of the internal battery (mAh - milliAmp-hours);
  2. the location reporting frequency;
  3. how frequently it alerts;
  4. the proportion of time that it spends moving;
  5. the strength of the available satellite radio signal.

Figures below represent typical/normal usage conditions under open sky, typically reporting up to 200 times per day. Reporting more than 400 times per day is abnormal usage. If a tracker has to work at high gain/amplification due to a weak satellite signal strength, it will deplete quickly. Lithium polymer batteries have a finite lifespan of 2-3 yrs typically, and may need replacement thereafter.


Warranty period:  12 months from purchase.

Discontinued use:  If a tracker hasn't reported for 6 months, we reserve the right to discontinue it, so as to stop paying its monthly SIM and platform rental. We will attempt to contact customers before doing this. It is best to keep a tracker charged and in regular use. Please read our Terms of service.
