The Port of Tacoma recently announced they are testing GPS satellite tracking systems to monitor containers that are being shipped across the United States. The goal is to obtain data from the tracking that will improve the speed and reliability during the movement of the cargo containers.

The Port of Tacoma is not alone in their proactive approach to achieve greater success with this new technology. Burlington Northern Santa Fe Railway and several other companies are joining in their lead to utilize GPS container tracking systems.

The container tracking systems are not just being used to put dots on a map, but to assists with scheduling, routing and delivery confirmation. An even greater benefit sought by these companies is an element of security. If the cargo makes an unscheduled stop or stops for a long duration, the proper steps could be taken to ensure the cargo is secure.

Unfortunately, not all global positioning systems are a perfect fit for this application. The challenges of GPS most commonly revolve around technology for which the device uses to communicate the tracking data to a ground station. Other issues include device size and battery life. Satellite tracking is generally more reliable, especially in remote areas, where GSM and CDMA technologies are not so reliable. While most people have been aware of the reliability with this technology; historically, it has not been the most affordable solution. However, the cost of this technology has dropped significantly in recent years.

Cargo containers, trains, trailers, and other equipment don’t usually have a power source readily available (if at all) to power global positioning systems that require a direct connection to power. In an effort to meet the demands for these applications, some global positioning system manufactures have built a device with a long lasting internal battery. Some of these devices, like the RMT Watchdog, will last up to seven years.

Now that the user application requirements have been satisfied, it’s apparent that satellite tracking technology is not just an optional tool, but an essential part of asset management and to stimulate further business opportunities. This technology is becoming more popular for companies seeking a leverage point over their competition, and there’s no doubt that it’s working.
