It can transmit your location from anywhere in the world and is built on the latest satellite, antenna, and electronics technology to track and monitor in real time. The GSatMicro measures just 45 x 45 x 29mm, including battery, modem and antenna! By utilizing the Iridium network, the GSatMicro can track an asset anywhere on earth. GSatMicro can be used in maritime, aircraft, personnel, and vehicles, and is ideal for applications such as: security and safety, fleet management, oil and drilling, soldier tracking, and government.

GSatMicro Tracker Key Features:

Global Coverage

The GSatMicro satellite tracker operates on the Iridium satellite network. This is the only commercial satellite network in the world to offer 100% truly global coverage, meaning the GSatMicro satellite tracker can show the location of your asset, wherever it travels across the globe.

Standard Messaging Mode

The GSatMicro satellite tracker is equipped with Location Based Services (LBS) enabling GPS positioning. The device is capable of transmitting its GPS coordinates from anywhere on the globe.

Dust & Water Resistant

The GSatMicro satellite tracker is designed to withstand the harshest weather conditions.


The GSatMicro satellite tracker is equipped with a programmable emergency button that activates critical, rapid response when you need it most. When pressed, the SOS button transmits your GPS coordinates and alerts your pre-specified contacts that you require assistance.


Using the two-way Iridium satellite constellation, the GSatMicro satellite tracker offers a ‘Follow-Me’ function. This enables you to ping the device, wherever it is located in the world, and instruct it to transmit its current GPS coordinates and status (device must be turned on with a satellite connection to enable this feature to function correctly).


In conjunction with OSAT Track, OSAT’s online mapping portal, the GSatMicro satellite tracker offers a geo-fencing feature. This allows you to predefine a set of geographical boundaries and be alerted by email when the device enters or exits the geo-fenced area.

OSAT Track Compatible

The GSatMicro satellite tracker is compatible with OSAT Track, our advanced online mapping portal. OSAT Track makes visible a variety of advanced tracking functions available on the SmartOne, such as a breadcrumb trails of historic movements, live view (position of last message transmitted) and alarm and input alerts. Asset locations and movements are tracked in real-time via GPS updates and available to view through a Google Earth based interface. These tracking functions are available with an additional subscription.

Send a message through your device to an email address or SMS number. Not all mobile networks allow you to send text messages to satellite networks and as a result text messaging can be unreliable. Please check with your provider or contact us for further information.


Automated tracking is available on this device meaning contacts back home can follow your journey or you can monitor the movement of your assets.


Once the emergency button is pressed on your beacon, your location will be sent to a rescue coordination centre via satellite. This SOS is then diverted to emergency services near to your location to aid rescue. The location will be continuously sent for a minimum of 24 hours.


This unit will allow you the ability to type, and send a custom message to friends, family or colleagues.  This is ideal to keep in contact when on the move.


Setup frequently used messages before your trip which can be sent at the touch of a button with no need for typing e.g. running late, arrived safely.


Messages can be sent and received by this device.
