How our trackers work:  GPS trackers are usually attached in some way to something or someone to show its location currently and in the past. Trackers send out location reports at regular intervals when moving, and sleep when not moving. They resume reporting when movement is again detected.
Location determination is done by detecting satellite orbiting the Earth, and their time signal radio waves that allow a tracker to work out its latitude and longtitude to 6 or 7 decimal places. Trackers need to receive these signals.
Reasons for deploying trackers include: asset protection; personal safety, recovery of stolen property. GPS2Find does not approve of their use in covert or illegal ways.
Some tracker models offer 2-way voice telephony options, and many health & well-being features.
 

2G 3G 4G Radio Bands: 2G network coverage will remain in use worldwide for many years to come, probably to the end of 2033 in Ire/UK, as it is heavily used for M2M data, meters, sensors, etc. Up to Dec2023, only Switzerland has turned 2G off.
Many new 4G modems feature 2G fall-back continuing its use. 4G trackers tend to be a lot more expensive than 2G. 3G is gone/discontinued.

Apps:  Our trackers have a Phone-App and a browser-based Web-App. This lets any number of people, who have been given access, to log in to see where one or more trackers is. This involves the tracker's ID, a username and optionally a password if the owner has set.  Its reporting frequency is typically set at about 1-10 minutes.  Our SIMs work almost anywhere in the World. A tracker recently went from Mayo to Mongolia and back, with a continuous (History) trail, as our SIMs roam free in most coutries.
The apps are simple to use, allowing non-technical people to use them, thereby avoiding the cost of a monitoring centre.  Our Trackserver trackers are fully licensed to use Google maps. Trackers are grouped by the apps they use - TrackServer or Aibeile trackers.

Alerts: Our trackers have the capability to send alerts if they detect
a) Motion - if it moves when "armed";
b) Over-speed - when/if it goes over a set speed;
c) Geofences - when/if it leaves or enters a particular place/zone/geofence defined by customer;
d) Panic - if its panic button (if any) is pressed;
e) Battery flat - if its battery drops below a user-set level - e.g. 20%.
The alerts may be by push messages within an app, by SMS or email, depending on tracker model and user settings.

Technical details:  GPS trackers contains a GPS module, a modem; an accelerometer to detect motion, and a rechargeable battery, akin to a mobile phone. They come in different package shapes and sizes. Size depends on battery size and whether it contains a magnet. When in the open or near a window/opening, they should receive the radio signals from numerous orbitting satellites (20,200km above Earth) from which they calculate latitude and longtitude to 6 decimal places. The accuracy of the calculated location depends on:
1) the physical setting / surroundings;
2) the strength of the satelite signals;
3) the time since the previous location report.
Weak signals and long time intervals between reports give low accuracy. The first location report after a long time should usually be ignored. The next one which adjusts the maths, will be more accurate. Trackers will not work if surrounded by metal, or deep inside buildings, reinforced concrete walls or floors, trees, etc. Position reports are sent via data packets across the mobile phone networks to a server and database.

Advantages of our trackers:

• Tracking possible using any type of internet device;
• We retain data for a long time - 1 year look-back history;
• Our SMS Gateway is very fast - alerts are received typically in under 2mins;
• Many alert options available to suit many uses;
• Multiple geo-fences/zones available simultaneously;
• Trackers work straight from their boxes and are already SIM-ed;
• Multiple operating modes (up to 6) to prolong battery life.

Antennas: Each tracker has two antennas, one for communication (GPRS/GSM) and one for satellite signal reception (GPS). These are located on the tracker's front (LED) face, the opposite side to magnets. This side must face "the outside world". The App & WebApp displays the last location reported 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. Internal battery size (mAh - milliAmp-hours);
2. The chosen location reporting time interval;
3. How often it sends alerts;
4. The fraction of time that the tracker is in motion;
5. The quality of the satellite radio signal. Poor reception makes the tracker's internal amplifier operate at high gain, wasting battery power.

Trackers typically reporting up to 100-200 times per day. Reporting more than 400 times per day is deemed excessive.

Warranty period:  Technically 12 months from purchase, but we seldom quibble over warranty dates.

Use or lose it:  If a tracker is not in subscription, and hasn't reported for 3 months, we may cancel it to stop paying the monthly charges it incurs. We will attempt to contact customers. Keep your tracker charged and in regular use. Please read our Terms of service.
