In today's fast-paced business landscape, efficient asset management and asset monitoring is the cornerstone of success for  many industries. As industries expand and operations become more complex, the need for precise asset tracking solutions has never been more critical. Today, GPS asset tracking is already successfully applied in supply chain visibility, container tracking, returnable packaging, cold chain monitoring, and many more applications. In this comprehensive guide, we delve into the cutting-edge innovations shaping the world of GPS asset tracking.

1. Low-power GPS asset tracking in the cloud

Traditionally, GPS asset trackers have calculated their location on the device and transmitted the calculated location through a cellular network to some asset tracking software. However, this approach has significantly limited the battery life of GPS asset trackers in the past, because of the power consumption of getting a GPS location fix. Recently, a new set of GPS trackers have emerged that no longer calculate the position on the device resulting in significant power savings. These devices capture only the minimal required information from the GPS receiver, and send this to the cloud, where the final location is calculated. In practice, this can result in a battery life that is a factor 10 better than traditional GPS asset trackers.

This so-called low-power GPS approach can give GPS asset trackers a battery life up to 10 years while still providing location updates several times per day. This basically results in a tracker that never requires new batteries resulting in a significant operational advantage of deploying GPS asset tracking at scale.

2. Infrastructure-less indoor asset tracking

GPS is great, but one significant downfall is that it doesn’t work indoors. Buildings typically block out the signals coming from the satellites which makes tracking impossible inside buildings, or even in cities with a lot tall buildings. Traditional GPS asset trackers would simply vanish from the map until the tracker would get reception again. For lot’s of applications, this is unacceptable.

Recently, GPS asset trackers are being equipped with Wi-Fi to solve this issue. The Wi-Fi will scan the network for Wi-Fi access points and send this information to the cloud. In the cloud, the location can be resolved by using a Wi-Fi access point database that some of the big tech companies provide, such as Google which already use this method for a long time for smartphone localization. The typical accuracy of this is 10m to 40m which is sufficient to know in which building the asset is located.

For better indoor accuracy, some GPS trackers also have Bluetooth equipped, which can increase the accuracy to 3m-5m, if a Bluetooth infrastructure is available at least. For even better accuracies, below 1m, ultra-wideband tags are the best way forward.

Nevertheless, the Wi-Fi scanning offers visibility inside buildings without requiring to measure out any infrastructure yourself. This is a major improvement to improve the reliability and visibility of GPS asset trackers.

3. Cost reductions of GPS asset tracking

Perhaps one of the most important improvements seen in GPS asset trackers recently is the cost reduction. As technologies improve and are more widely used, the cost goes down. This is definitely true for GPS asset trackers. These trackers are typically packed with multiple technologies such as a GPS, Wi-Fi, Bluetooth, IOT sensors and cellular technology. All of which, the price is going down.

Before, the cellular network technology typically represented one of the most expensive pieces of a tracker. What we see now is that for this technology, and most specifically NB-IOT, prices have decreased significantly. NB-IOT is a long-range low-power wireless technology which is part of the 4G and 5G standard and is specifically designed for low-power long-range communication in IOT sensors. A recent market study by Counterpoint research, shows that NB-IOT is massively being adopted resulting in prices going down for the hardware, as well as for the data subscriptions.

In 2023, we see that prices for GPS trackers are dropping to levels that make the return-on-investment better than ever, allowing for more wide-scale deployments.

4. IoT-enabled Sensors

The Internet of Things (IoT) has revolutionized outdoor GPS asset tracking by enabling real-time data collection and analysis. IoT-enabled (low-power) sensors provide businesses with valuable insights into asset conditions, including temperature, humidity, and motion. This data is pivotal for industries such as pharmaceuticals and food transportation, ensuring the integrity of goods throughout their journey. As these sensors are becoming increasingly low-power and low-cost, they can be added to enable additional functionality like impact detection, theft detection, and run hour monitoring, and more.

5. Cloud-Based Solutions: solving real use-cases

Cloud-based asset tracking solutions, such as the Pozyx Platform, offer unmatched scalability, allowing businesses to seamlessly expand their tracking capabilities as their operations grow. However, what's even more important, is that these solutions have matured and that they can solve a diverse set of use-cases in logistics, supply chain, returnable packaging and more. Integrating these applications has become increasingly easy through open API's (like the Omlox open location standard), and the adoption of the low-code/no-code principle results in easily configurable systems that remain extremely powerful. In the end, the true value of any asset tracking system lies in its application.

Is GPS asset tracking right for you?

As we’ve seen, GPS asset tracking solutions are continuously improving. But are they right for your application? For most outdoor tracking applications, using GPS trackers still makes the most sense, and with the additional visibility indoors, they have eliminated some of the downfalls of GPS technology alone. For more accurate sub-meter indoor tracking or for lower cost solutions, you’ll still want to look at alternatives like bluetooth or ultra-wideband tracking, at the expense of loosing some of the visibility outdoors.
