If you’re reading this, chances are you rely on GPS asset trackers to keep tabs on your fleet, high-value equipment, or even mobile work vehicles. As a GPS asset tracker supplier who’s been in this space for over a decade, I’ve seen firsthand how a tracker that seems like it should work perfectly on paper can fall short in real-world moving vehicles. A hardware that’s rated for 100 hours of battery life might die halfway through a long haul, or a unit that claims “real-time tracking” might skip 20 minutes of data while your truck’s on a remote highway. The good news? Most of these issues aren’t because the product is flawed—they’re because of small, often overlooked choices around installation, environment, and maintenance that make all the difference. Over the years, I’ve worked with hundreds of fleet managers, construction company owners, and delivery operators to get their trackers working as intended, and I want to share those lessons here.

Let’s start with the most critical step: installation. You can have the highest quality GPS hardware on the market, but if you mount it wrong, it’s useless. I once worked with a regional delivery company whose trackers were cutting out 30% of their stops, and it took us three days to figure out why. Their technicians were mounting the trackers under the dashboard, right next to the vehicle’s OBD-II port and a big metal fuse box. That metal was blocking the GPS signals—GPS relies on line-of-sight to at least four satellites, so anything that sits between the unit and the sky will disrupt it. The fix was simple: move the tracker to the roof, under the headliner, where there’s unobstructed access to the sky. Now, most modern vehicles have a lot of metal and electronics crammed into the cabin, so even the roof might not be ideal if you have a panoramic sunroof or a heavy steel roof rack covering the mounting spot. If that’s the case, we recommend mounting it near the A-pillar, just above the windshield. The windshield is made of laminated glass, which doesn’t block GPS signals nearly as much as solid metal, and that spot stays out of the way of any moving parts like sun visors or passenger seats.
Another common installation mistake is grounding the tracker incorrectly. A lot of people tap into the vehicle’s auxiliary power or OBD port, which works for basic functionality, but in moving vehicles, especially ones that go over rough terrain, power surges and drops are common. A construction vehicle that bumps over potholes might send a sudden jolt of voltage that fries the internal circuit of a cheap tracker, or a delivery truck that shuts off its engine mid-route to make a drop might cause the tracker to reset and lose its connection to satellites. We always tell customers to hardwire their trackers directly to the vehicle’s battery, with a built-in surge protector and a low-voltage cutoff. That low-voltage cutoff is key: if the vehicle’s battery drops below a certain level (say, 11.8 volts for most trucks), the tracker will shut down gracefully instead of draining the battery completely. I’ve had customers tell me their vehicles were getting dead batteries because the tracker was running all night—this fix eliminates that problem entirely. We include a pre-wired power harness with every tracker we sell, and our technicians will walk customers through installation step-by-step over the phone; half the battle is making sure you don’t skip those wiring safety steps.
Next, understanding how the moving vehicle’s environment affects the tracker. Moving vehicles are nothing like the static test units we use in our lab. A truck going 70 mph down the highway has constant vibration, for example. Over time, that vibration can loosen internal components, disconnect antennas, or wear out the battery of a portable tracker. For that reason, we never recommend using portable, magnetic-mounted trackers for long-term vehicle installations. Those magnetic ones are great for temporary use, like tracking a rental car or a piece of equipment that moves between sites, but in a permanently assigned delivery truck or a work van that’s on the road every day, the vibration will make the magnet weaken, and the unit might fall off, or the internal connections will come loose. Instead, use a screw-mount bracket that’s rated for automotive vibration. We design all our trackers with vibration-dampening rubber mounts, and when you pair that with a solid screw mounting to the vehicle’s frame (not just the interior panel, which is thinner and more prone to shifting), you cut down on most of that wear and tear. For heavy-duty vehicles like dump trucks or semi-trucks that go over off-road terrain, we even recommend adding an extra layer of vibration padding between the bracket and the mounting surface—small, but it extends the lifespan of the tracker by years.
Temperature is another big factor most people don’t consider. Moving vehicles can swing from extreme heat to extreme cold, depending on where you operate. A delivery truck in Arizona can get up to 140 degrees Fahrenheit inside in the summer, while a utility vehicle in Alaska might drop to -20 degrees in the winter. Consumer-grade electronics only work in a narrow temperature range, usually between 32 and 122 degrees. Our trackers are rated for -40 to 158 degrees, which makes them suitable for all climates, but that doesn’t mean placement doesn’t matter. If you mount the tracker right on the engine block, the heat from the engine will push it over its rated limit over time. We recommend mounting it in the vehicle’s cab, not near the engine bay or exhaust system. The cab stays at a much more consistent temperature, and while it can get hot, it’s never as extreme as the engine area. We also test every unit in temperature chambers for 100+ hours before we ship them, but a bad installation can undo that design work.
Then there’s data connectivity. Most GPS asset trackers use cellular networks to send location data back to your platform, right? So if your moving vehicle is in an area with poor cellular coverage, the tracker won’t send data. I’ve seen this happen to logistics companies that operate in rural areas or remote construction sites. A truck driving through a mountain pass might have no 4G signal, so the tracker stores the location data locally until it gets back to an area with coverage, but if the storage is full, it might start overwriting old data instead of saving new ones. The key here is choosing a tracker with the right cellular band for your operating area. We offer trackers that work on all major global networks, and we make sure our customers pick the one that has the strongest coverage where their vehicles run. For customers who operate in areas with very limited cellular coverage, we also offer trackers with satellite connectivity options. Those trackers use low-orbit satellite networks to send data, so even if your vehicle is in the middle of the desert or the open ocean, you’ll still get location updates. The only catch with satellite trackers is that they use a bit more battery, so we adjust the update rate accordingly—if you’re going to be in a remote area for two weeks, we recommend setting the tracker to send a location update every 15 minutes instead of every minute, which saves battery without sacrificing too much visibility.
Regular maintenance is often the last thing on people’s minds when it comes to GPS trackers, but it’s just as important as installation. A tracker that works when you first install it might start failing after six months if you don’t check it. We recommend doing a quarterly check of all trackers in your fleet. First, make sure the mounting bracket is still tight—vibration can loosen screws over time. Then, check the power connections to make sure there’s no corrosion, especially if you work in areas with lots of salt or moisture (like near the coast, or in areas that use road salt in the winter). Corrosion is the number one cause of power issues in trackers, because it creates a bad connection between the tracker and the vehicle’s battery. If you see any rust or white buildup on the wires, clean it off with a little baking soda and water, and re-seat the connection. We also recommend doing a signal test every quarter. Most of our customer platforms have a built-in signal strength meter, so you can see if the tracker is getting enough satellite and cellular signal. If the signal is low, you might have moved the vehicle to a new area with more metal structures, or the tracker’s antenna might be damaged—we’ll send a replacement antenna for free if that’s the case.
Another thing I see a lot is setting the wrong update rate. Some people set their trackers to send location updates every 10 seconds, thinking that will give them perfect visibility of their moving vehicles. But that’s a waste of battery and data, especially for long-haul trucks that drive the same route every day. If you set the update rate too high, the tracker will burn through its battery faster, and you’ll pay more for data overage fees. On the flip side, if you set it too low—like every hour—you might miss a delivery delay or a breakdown because you don’t have real-time data. The sweet spot for most moving vehicles is every 1 to 5 minutes for on-road use, and every 15 minutes for off-road or remote use. You can adjust that rate remotely from your platform, so if you have a vehicle going on a long trip, you can bump up the update rate temporarily, then lower it when it’s back on your usual route. That flexibility is one of the biggest benefits of modern GPS trackers, and a lot of customers don’t realize they can adjust those settings without physically touching the tracker.
I also want to talk about common misconceptions. A lot of people think that more expensive trackers are always better. That’s not true. I’ve had customers buy top-of-the-line trackers from big brands, only to have them fail because they installed them incorrectly. Conversely, we’ve had small business customers use our mid-range trackers, mount them right, and get perfect, reliable data for years. The quality of the hardware matters, but it’s only one piece of the puzzle. Another misconception is that trackers will work anywhere in the vehicle. I once had a customer mount a tracker in the trunk of a sedan, and because the trunk was lined with heavy sound-dampening material, the GPS signal was blocked completely. Even if the material looks thin, some of that sound-dampening foam is metalized, which is a total GPS blocker. That’s why we always advise against mounting trackers in trunks, under carpets, or near any kind of metal lining.
At the end of the day, ensuring your GPS asset tracker works in a moving vehicle is about attention to detail, not just buying the right product. It’s about taking the time to mount it correctly, choosing the right power setup, accounting for the environment, doing regular checks, and adjusting settings to fit your specific use case. If you follow these steps, you’ll get consistent, reliable location data, which will help you reduce fuel costs, improve driver safety, recover stolen assets, and keep your operations running smoothly.
