We use 2 types of trackers in our mapping. GPRS which use Telstra signal to get messages out and Satellite trackers for areas with no mobile signal.
Trackers – GPRS
We have a fleet of 400 GL300W GPRS trackers for events. These robust little units are approximately the size of a match box and weigh only 72 grams. They send out their location to the maps at 90-second intervals. This interval can be increased if longer battery life is needed. See the table below for battery life vs message below.
The trackers are GPS units which means they use satellites to work out their position then they send this information to a LIVE MAP on the web using the mobile network. They use the Telstra Next G Network in Australia which ensures the best coverage in metropolitan and rural areas. They even have coverage out to sea in most places for 20 to 30km! Outside of Australia, they roam on local telecommunication provider towers.

Tracker Size: 78mm high x 40 mm wide x 22mm deep. Total weight 72g. A little larger than a matchbox
The trackers are not water proof but can be supplied with a waterproof container.
They are rechargeable units and are able to send out messages at the following interval.
|Message Interval||Expected Battery Life|
|90 seconds||28 Hours*|
|2 minutes||32 Hours*|
|5 minutes||72 Hours*|
|10 minutes||96 Hours*|
|* battery life can be reduced by cloud cover, tree cover , being indoors and cold temperatures.|
If you require the tracker for a longer event where you will not have access to power to recharge, we are able to supply an external lithium battery in a water proof pelican casing. This greatly increases the battery life of the units.
Trackers – Satellite
If the area that you are operating in has no mobile signal, often the only choice is to use a Satellite Device. We don’t own any devices but regularly facilitate hiring them from a 3rd party. The specific device we would recommend depends on your individual circumstances.
All Satellite devices carry a higher price tag than a GPRS unit. Generally, a low end would start at $80 per tracker right through to $200. Pricing changes depending on trackers hired and whether you need 2 way messaging.
All trackers use the same mapping system (front end) as the GRPS.
It is a complicated area and one we are happy to provide general advice on over the phone if you think you may be interested.
