GPS technology has become almost ubiquitous in modern life. Most of us use it everyday without a second thought. But do you really understand it? And do you know how to get the most out of GPS tracking to improve your fleet's operational efficiency?
Fleet managers use GPS on a daily basis to keep track of their fleets and other assets. They can get information that helps them solve issues such as compliance, efficiency, and safety. But how does this happen? What is GPS tracking and how does it work?
Let's begin with the name, GPS, which stands for Global Positioning System. The system involves a network of satellites orbiting the Earth and devices that can help determine an object or a person's location. Initially developed in the 1960s for military application, GPS technology eventually became available for public use in 1983, and advances and use cases have increased over the decades. These days, GPS has a range of uses, from military exercises across the globe, to directions that help drivers find their way.
A GPS tracking system does this by using the Global Navigation Satellite System (GNSS) network. This network consists of satellites that communicate with GPS devices to provide information on the current location, direction, time, and speed of the vehicle being tracked.
GPS tracking devices send special satellite signals that are processed by a receiver. These GPS receivers track the exact location of the GPS device as well as compute their time and the velocity they are traveling. These positions can also be computed and represented in three-dimensional views using four types of GPS satellite signals. GPS systems consist of three segments: space, control, and user.
The Global Positioning System is made up of 27 satellites that orbit the Earth. Of these 27 satellites, 24 are operational, and three are backup satellites if one of the other 24 fails. These satellites orbit the Earth every 12 hours and send signals that are received by GPS receivers.
The Positioning System is controlled by different tracking stations located around the globe. These stations pick up microwave carrier signals transmitted by the satellites, and the GPS receivers convert these signals into data such as velocity, time, and position.
GPS receivers receive the signals sent by GPS satellites and use them to determine the user's position in space and time.
There are a few ways a GPS tracking system can work. Commercial GPS devices are often used to record the location of vehicles during their journeys. Some systems will store information within the GPS system itself, and this is called passive tracking. Other systems regularly send data to a centralised database through a modem, and that is called active tracking or 2-way GPS.
Passive GPS tracking monitors location and stores data on trips based on specific events. This type of system can log data on where the devices have been in the past 12 hours. It stores the data internally or on a memory card, which is then downloaded to a computer to be analysed later. In some systems, the information is downloaded automatically at a set time or can be requested periodically during the journey.
Passive GPS entails real-time tracking systems that automatically send information to a central tracking portal as it happens. This type of system is used on most commercial applications, such as monitoring and tracking children or the elderly, since it lets caregivers know where their charges are at all times. This type of system is also used to monitor employees' behavior as they work and streamline a fleets' operations.
Most people are familiar with the most common uses of GPS technology, such as mapping and surveying, getting directions, and keeping track of children. But there are many other uses you may never had realised were out there. GPS plays an important role in all types of applications used by the military and first responders, as well as other commercial and personal uses. Here are some of the ways GPS tracking systems are used.
Initially developed by the military, GPS is still used to track troop movements, aircraft, navigation at sea, and more. This is very important for military units stationed in unfamiliar territory or on the move at night.
GPS tracking is also used in search and rescue operations. It helps rescue teams keep track of where they've searched or even get information from a lost person's phone or GPS device.
Commercial fleets often use GPS tracking to monitor their fleet vehicles. By installing GPS devices on fleet vehicles, fleet managers can track their drivers' locations and statuses, as well as get important insights about their fleet's efficiency.
Most wearable tech such as watches used for running, biking, and hiking, use GPS tracking, giving users input on distance traveled, their speed, or where they are in the wilderness. With the increase in smartphone use, almost all of us carry GPS tracking devices everywhere we go. This technology can be used in new ways, including augmented reality (AR) applications to location-based games. These types of uses will only increase in the coming years.
Privacy concerns surrounding GPS tracking have resulted in legislation on how these tracking devices can be used. It's completely legal to install a GPS device on a vehicle or asset you own. But using a GPS tracking device on a person or in someone else's vehicle, requires you to check the current federal, state, and local laws. These laws change continually as new cases come up, so it's crucial to keep yourself up-to-date on amendments. Here's what you need to know.
Be clear and transparent about when and how you use GPS tracking data. If your employees don't trust or understand how you are using the data from GPS trackers, it can result in low employee morale.
Telematics and GPS tracking work together to provide actionable insights into the operations of your fleet. They are not competing systems but parts of a complementary system. At the center of a telematics system is a tracking device that gathers real-time data about the vehicle's location and status. A telematics solution receives GPS data and sends it to a central server. The data is then processed and turned into information that is accessed through fleet management software.
GPS tracking is a practical tool for fleet managers for many reasons. GPS devices give you visibility into your fleet vehicle's locations, but that's not all. Here are some other key benefits of GPS tracking.
A GPS tracking system lets you optimise your fleet's routes. You can easily locate your drivers and determine which is closest to a particular job. You can send the closest driver and reroute the rest of your vehicles if needed. This saves you time and money, while keeping your customers happy.
No matter if you are reducing fuel costs by sending your drivers on more efficient routes or making better dispatching decisions, GPS tracking devices can help you make cost-saving decisions based on data in real-time. By giving you increased insight and visibility into your fleet's operations, GPS tracking provides more data about your fleet vehicles, so your decisions can be more strategic and impactful to your business and its bottom line.
Prior to advances in GPS telematics, fleet managers had no way of knowing what their employees did each day, where they were at any given time, and where they were headed to next. They had no way to know who to dispatch for jobs, when the jobs were completed, or if they were even getting done.
With GPS tracking and better dispatching, you can economise on fuel use, save time and reduce emissions. For example, you can use GPS technology to monitor over speeding or excessive idling, fuel-wasting behaviours. You can coach your drivers to encourage better driving, saving fuel.
Installing a GPS vehicle tracker on your fleet vehicles and assets helps increase fleet security. If a vehicle or asset is stolen or lost, a GPS tracker can help you find and recover your stolen or lost vehicle or asset faster. You can even set a geofence around vehicles and assets that alert you when they leave the pre-designated area or are used off-hours.
With better journey management and electronic time logs, you can reduce overtime throughout your fleet. You'll be able to better allocate resources based on real-time insights, so that your trucks won't take longer trips and your drivers won't spend more time on the road than they need to. This helps keep your payroll hours under control.
Timesheet fraud takes place when drivers get paid for work they didn't do or for time spent on non-work activities. Sometimes drivers record more hours than they worked, retroactively edit their driving hours, or log regular hours as overtime. Not only does this cost you money, but it also can result in incorrect billing. By using GPS and electronic logs, your payroll and billing are more accurate.
A GPS tracking telematics solution can give you insight into real arrival and departure times, stop durations, travel time from one job to another, and when your drivers are inactive. This information can tell you if jobs are being completed in the allotted time, if there are delays - and why, if detours are taken for personal errands, and when delays occur due to a driver becoming lost. You'll know if drivers are not being utilised even if they have hours available, and you can make decisions based on real-time insights to improve overall fleet utilisation.
On occasion, your customers may question what you've billed them for, such as if a driver attended to their job and how many hours were spent on it. GPS tracking provides records of where your drivers were, and demonstrate to your customers that they worked the hours on their invoices. Showing your customers electronic proof can build trust, loyalty and improve your customer service.
GPS fleet tracking software works for all assets, not just vehicles. If you have expensive mobile equipment, such as generators and trailers, you can monitor their movements. This empowers you to know if they are on the jobsites where they are needed, and not sitting idly and unused. You'll know they are secure and accounted for. You can also set a geofence around worksites, so you'll know when they come and go from each specific site.
Improving fleet safety saves you money and improves your company's image. Now, GPS fleet tracking solutions can alert you when your drivers are speeding, making unscheduled stops, harsh braking, or suddenly accelerating. These actions not only waste gas and increase your fuel costs, but they can also be dangerous. By monitoring these events, you can help your drivers develop better, safer driving habits.
No matter if your fleet is delivering products to homes or is part of a complex supply chain, your customers expect a certain type of service and convenience. Since GPS tracking telematics gives you the exact location of your fleet's vehicles and you can dispatch your vehicles far more efficiently, your customers will be happier. You can provide them with increasingly accurate estimated arrival times (ETAs), so they will know when to expect a delivery or other service.
