GPS Tracking Devices – Made Simple by G-Layer

A quick and clear comparison of satellite GPS tracking devices on the market, for your convenience.

Today we want to take a look at the satellite tracker market, to help you the customer come to the same conclusion we have at G-layer. That is the Yellowbrick3 tracker offers by far the best feature-set for the money. Without naming names, let’s have a quick look…

We will do a comparison between the InR**ch SE, S**T Gen3, and the Yellowbrick3.

Message Length

First we will look at how many characters you can send in a message from each tracker. The InR**ch gives you 160, the S**T only lets you send preset messages, (as it has no screen or keyboard). The Yellowbrick3 gives you a full 5000 characters if you need it. The clear winner here is the Yellowbrick3.

Battery Life

Battery Life is a tricky thing to quantify, but we’ve used the manufacturer’s own estimates here, based on a tracking update of 10 minute intervals. The InR**ch will run for 4 days, the S**T will go for 9 days, but both are eclipsed by the Yellowbrick3 which will run for about 17days.


The S**T is out of this one, with no screen at all, so it’s between the InR**ch with its colour screen and the Yellowbrick3 with it’s very crisp and clear Oled mono screen, viewable in full daylight. Let’s be generous and call it a draw.


The good news is all the trackers are waterproof, but the S**T specifies only IPx7 as opposed to IP67 for the other two. Another draw here.

Yellowbrick Tracker and MessengerRuggedness

Ruggedness is measured by the military standard MIL810. All trackers meet this standard, but the Yellowbrick3 is the only one to comply with the F/G specification, so it inches ahead here.

SOS button

Both the InR**ch and the S**T send messages to GEOS services only, whereas on the Yellowbrick3 you can define exactly the behaviour of the alert button to send alerts to whoever you wish, via text and email. We should note that S**T does allow predefined recipients, but on a different button. Let’s call this one a draw.

Fastest Tracking

The clear winner here is the Yellowbrick3, which blows away the competition with its tracking speeds down to 40 second intervals. It can even be put in burst mode, for up to 5 second gps readings, useful for very high speed tracking.


The S**T is out of this particular race, as it only allows one way preset messages, whereas the other two trackers are both two-way, It’s obviously quite useful to be able to text back to the tracker, especially in an emergency situation. So it’s a “two-horse race” for this category and another draw.


Both InR**ch and Yellowbrick use the ubiquitous Iridium satellite constellation, with absolutely no black spots across the whole planet (yes really). This is the real achilles heel of the S**T, as their coverage has major limitations, and in some areas including most oceans, there is no coverage at all. Many countries also have no S**T coverage or contracts.

Contracts and Lock-ins

The Yellowbrick3 is another clear winner here, with the other two companies requiring contracts with a lock-in of 12 months, at considerable up front cost. The Yellowbrick lets you use the tracker when you need it, on a month by month basis, with no lock-in or complicated contract. You only pay for the month you need, and the credits you use – it doesn’t get simpler than that.

Finally, let’s put this info into a nice colour coded table to make it clearer.
