The AssetPack-3 (AP3) global satellite tracker is a highly versatile, low cost of ownership two-way asset tracking and sensor monitoring solution, designed for frequent two-way communication with unpowered assets. Using the Iridium satellite network, the AP3 is a completely enclosed, self-contained, waterproof, dustproof, fully-ruggedized solution that enables pinpoint monitoring of any fixed or mobile asset anywhere on the ground, at sea, or in the air. Available in solar/line power or hard-line only options, the battery lasts the lifetime of most industrial equipment. For applications beyond GPS, it can be rapidly configured to monitor a wide range of analog and digital sensors and inputs. Its fully two-way communication capability supports over-the-air commands to change reporting behavior or manage machinery.
