Cattle GPS Tracker Size Comparison

Worlds smallest livestock GPS tracker

Measuring only 2.2″, the GSatSolar is the worlds smallest and most powerful livestock GPS tracker.  Not only is this the smallest tracker, but it is also the lightest tracker in its class, weighing only 22 grams. 

Adaptable to all types of animals

The GSatSolar can be easily connected to the ear of your cattle with the use of a universal tagger.  Or if you need to track other animals, you can easily connect the GSatSolar to a collar.  This makes our tracker one of the most adaptable and universal livestock tracking devices on the market.

Satellite GPS Coverage Map

Global coverage

The GSatSolar uses the Globalstar LEO satellite constellation to transmit animal location data once every 6 hours.  Our tracker does not use cellular service, which means your tracker will work almost anywhere

Affordable animal GPS tracking

The GSatSolar has one of the lowest up-front investments and includes 2 years of service.  While other tracking systems require that you deploy an infrastructure and gateways, simple attach the GSatSolar to your livestock, and you are ready to track.

6 Hour location updates

The GSatSolar is designed to update the animal location once every 6 hours, 24 hours a day.  The device is solar powered which means there are never any batteries to replace or recharge. 

What happens after the first 2 years?

We guarantee that your tracker will last at least two years.  Some devices will continue to work for another year, while others may fail after the first two years.  Both the solar panel and internal battery will weaken over time and will need to be replaced.  We estimate the internal battery and solar panel to last somewhere between 2.5 and 3 years.  At the end of the lifespan, the device will no longer function and will need to be refurbished or replaced.   All users can expect a minimum of 2 years of service from the device.

Warning – Modifications:

Changes or modifications to the internal parts not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

Warning – Blasting Area:

To avoid interference with blasting operations, turn your transmitter off when in a “Blasting Area” or in areas posted “Turn off two-way radio.” Obey all signs and instructions.

Warning – Potential Explosive Atmosphere:

Turn off the transmitter or any product with the transmitter installed when in any area with a potentially explosive atmosphere and obey all signs and instructions. (End products specifically designed to work in Explosive Atmospheres are to follow their certification guidelines.)

Warning – Pacemakers:

The Health Industry Manufacturers Association recommends that a minimum separation of six (6”) inches be maintained between the transmitter and a pacemaker to avoid potential interference with the pacemaker.

Warning – Hearing Aids:

Some digital wireless devices may interfere with some hearing aids. In order to prevent such interference, you may want to consult the manufacturer of your hearing aid.

Warning – Specific Absorption Rate (SAR):

FCC / Canada:

The transmitter has been shown to be compliant to localized Specific Absorption Rate (SAR) for uncontrolled environment/ general exposure limits specified in ANSI/IEEE STD C95.1-1992 and has been tested in accordance with measurement procedure specified in IEEE 1528-2013 and IEC 62209- 2.2010 using a separation distance of 20 cm.

European Union (CE RED):

The transmitter has been shown to be compliant for localized specific absorption rate (SAR) for uncontrolled environment / general exposure limits specified in ANSI/IEEE Std. C95.1-1999 and has been tested in accordance with the measurement procedures specified in EN50566:2017 and EN62209- 2:2010 using a separation distance of 20 cm.

NOTE: If concerned about RF exposure during use, place the transmitter away from your body. The RF exposure level drops off dramatically with distance from the antenna.
