It’s almost unimaginable today that someone in North America wouldn’t have experience with a global positioning system (GPS). Most of us have GPS devices on our phones, and many of us have GPS trackers in our cars. Commercial fleets can also use GPS tracking to improve productivity and track assets. Yet how many of us actually understand how GPS works? This blog answers that question and shares the many applications and advantages of GPS tracking systems.

What is GPS tracking?

In simple terms, GPS is a technology that tracks the location of an object. While GPS tracking is a relatively new technology, the process it uses to track objects has been around for well over one hundred years.

Triangulation is at the heart of what GPS does. Before satellites, triangulation measured distances. With the invention of radios, we used the same technique of measuring the strength of a signal and direction to triangulate where a signal originated.

Satellite navigation relies on radio signals transmitted from medium-earth orbit. GPS satellites emit signals used by GPS tracking devices to accurately determine location and time.

It may sound complicated, and a little rocket science is involved, but what GPS tracking means for your company is that you can know where a vehicle is, how fast it’s traveling, and the estimated time of arrival.

What is the history of GPS?

The system was originally developed by the military in the 1960s. The United States Navy began using satellite navigation to track submarines carrying nuclear missiles. By sending and observing signals to six satellites in space orbiting the poles, the Navy could find submarine locations within minutes.

The Department of Defense (DoD) got on board with the idea in the 1970s and launched the first Navigation System with Timing and Ranging (NAVSTAR) in 1978. By 1993 it was a fully operational 24-satellite system for multi-use navigation.

Today, there are 31 GPS satellites operated by the U.S. as part of the Global Navigation Satellite Systems, which serve the international community.

How does GPS tracking work?

A GPS tracking device, fitted with a receiver, is attached to the object you want to monitor. The device is also built to record the time and its location (using latitude and longitude) in relation to the GPS satellites.

Finding one object’s location takes multiple satellites. While hurtling hundreds of miles per hour in space, the satellites bounce a signal back and the time it takes for it to return allows the transmitter to calculate the distance from each satellite. The receiver uses the difference between the signal broadcast and reception time to compute distance.

The more satellites that send back a signal, the more data there is with which to make a precise measurement. Accounting for delay and signal speed changes caused by the fact that it’s traveling through the earth’s atmosphere, the GPS uses information about the device’s range from three satellites, and the location of the satellite when the signal was sent, to plot a three-dimensional position.

Then, at regular intervals, the receiver relays that location data to the GPS tracking software. Data relay may be done in near real time (if the device has its own data transmitter) or can be downloaded manually from the device. The GPS tracking software takes that recorded data and translates the logged information into a location on a map. The Motive Asset Gateway captures data every minute and reports it to the user’s dashboard while cable powered.

What are the uses of GPS?

Designed and maintained by the U.S. government, GPS tracking is today operated by the United States Air Force to meet national defense and homeland security needs. Still, it has many commercial applications too.

1. Vehicle tracking

This can apply to passenger or commercial vehicles. For example, most new car models today come factory-fitted with GPS to enable private car owners to use satellite navigation. This has increased driver satisfaction with their vehicles while also helping to reduce fuel expenses as individuals are able to take more efficient routes to their destinations.

2. Fleet tracking

In addition to tracking a single vehicle, fleet tracking uses GPS to monitor and dispatch many vehicles, assets, and trailers. The applications include:

  • Taxi services
  • Commercial fleets
  • Freight trucks
  • Waste management
  • Public transportation
  • Emergency vehicles
  • Roadside assistance
  • Trailer tracking
  • School busses

3. Heavy machinery

Mining and construction businesses, for instance, use GPS to make it easy for drivers to follow pre-programmed site plans and achieve close tolerance for position, gradient, and level. With in-cabin vehicle guidance and control systems, it’s also easier to avoid the delays that can slow down a site and cause unforeseen expenses.

GPS tracking also provides an overall map view of all the moving parts on a mining or construction site. This makes it much easier for site managers to monitor fuel use, inventory availability, and employee productivity. Further, they have the data they need to manage payroll, validate invoices, and do root cause analysis if problems arise. Preventative maintenance is also simplified as the technology makes it easier to track wear-and-tear on assets and anticipate when frequently used equipment needs some TLC.

4. Agricultural use

Farmers now put GPS receivers on tractors and other farming equipment for better fleet asset management throughout the planting, weeding, and harvesting seasons. GPS tracking enables precision farming with farmers able to do more accurate farm planning, field mapping, soil sampling, crop scouting, and yield mapping. GPS-based tractor guidance also helps farmers work in more difficult conditions (rain, dust, fog, and darkness) while the navigation tools enable maximum ground coverage in the shortest possible time.

With more precise application of pesticides, herbicides, and fertilizers, farmers can also reduce expenses and see a higher crop yield while being more environmentally friendly.

5. Route planning

GPS is all about accurate and timely information, which is just what you need to do the best route planning. GPS tracking systems not only provide real-time awareness of asset positioning, but also help you determine how to get from one location to another and determine the expected timing.

GPS planning makes it easier to find the best approach to a multi-stop route. Plus, the driver is aided by turn-by-turn directions that can take into consideration changes along the way from weather, traffic, or other constraints.

6. Vehicle or asset recovery

Many GPS tracking systems today allow you to find a vehicle or asset if it is stolen. Even when the stolen vehicle or asset is in motion, you can track the whereabouts to facilitate recovery.

Many GPS tracking software also allow you to set up a geofence perimeter to help prevent theft. Operators can be alerted if an asset leaves a pre-established perimeter.

How accurate is GPS?

That depends. The satellites are equipped with highly accurate atomic clocks and the U.S. government is committed to broadcasting the GPS signal in space for an accuracy range of less than or equal to 2 meters (6.6 feet), with 95% probability. Yet, the signal does depend on other factors including satellite geometry, signal blockage, atmospheric conditions, and receiver design features/quality.

GPS-enabled smartphones, for example, are typically accurate within a 4.9 meter (16 feet) radius under an open sky, but GPS accuracy suffers near buildings, bridges, and trees. Trying to receive the signal indoors or underground can also degrade GPS accuracy.

And, in case you’re wondering, the U.S. government lets civilian and commercial users have the same level of accuracy in GPS signaling as the military uses. That wasn’t always the case, but in May 2000 the Clinton administration directed the government to do away with Selective Availability.

Do you need GPS tracking?

Any organization that operates commercial vehicles may benefit from GPS tracking. Taking the satellite signal for navigation and coupling it with software that integrates real-time insights into location, speed, and other data suits several scenarios. When considering a top-rated GPS tracking system ask yourself if you want to:

  • Protect valuable assets in the case of theft
  • Reduce fuel and maintenance costs
  • Improve route efficiency
  • Provide driver training opportunities
  • Reduce insurance costs
  • Improve customer satisfaction
  • Find operational efficiencies

What are the benefits of GPS tracking?

A GPS system is a must-have for companies of any size with vehicles on the road.

The most advanced GPS systems collect location points every 30 seconds and are also based on changes in speed and bearing. This offers many important benefits.

1. Gain GPS location and alerts

A GPS system is most useful if it automatically sends an alert when certain conditions are met, such as when a vehicle leaves or enters a boundary. Plus, with a high-end GPS system, drivers can easily transmit location information without having to make a phone call. This lets you track your fleet accurately, while improving driver satisfaction and increasing overall efficiency.

2. Route efficiently

The shortest route between two points doesn’t always mean the fastest. Using the history of travel routes collectively, a GPS tracker can calculate the fastest route based on the time of day and traffic congestion or road construction.

3. Reduce detention times

Find out which pick-up and drop-off queues are taking longer than they should so you can reduce idle time. After all, idle time can cost up to $1,200 per driver per year. Decreasing detention can also increase safety.

Addressing idling also has fleet benefits. Detention can increase engine wear, resulting in more maintenance. Detention also increases the carbon emissions of your business and increases fuel and labor costs.

4. Tighten your delivery window

Food or other perishable deliveries live or die on fast delivery times. With real-time GPS asset tracking, you’ll be able to provide a tighter delivery window for your customers. You can also notify clients when the unexpected collision has your delivery locked up in traffic.

5. Improve customer service

Clients love a heads-up when expecting a delivery. The best GPS software allows you to notify them automatically. With real-time visibility, customers have the most accurate ETAs so they can prep their worksite, warehouse, or receiving dock for your vehicle’s arrival.

6. Enjoy data insights

Complete visibility into your fleet via GPS tracking software can help you identify the causes of increased fuel consumption. Does one vehicle in the fleet refuel more often than the others just like it? It might be due for maintenance. Is one driver more prone to jackrabbit starts or harsh braking (or worse, taking personal errands or side jobs)? You can address that with more training or coaching.

7. Reduce paperwork

Throw out the old mileage logbook. Yes, the one with the coffee stains all over your driver’s chicken scratch handwriting. With an intuitive app in the GPS tracking software, your drivers can perform daily tasks up to 50% faster and keep up with communications back to the office seamlessly. This also does away with waiting days or weeks to receive pertinent data from drivers out on the road.

8. Integrate with your ELD

If your drivers are subject to electronic logging device (ELD) regulations, a good GPS system will integrate with the ELD and work hand in hand with that system to help the driver stay compliant.

An ELD integration can:

  • Notify drivers of required upcoming breaks and alert them of HOS violations approaching
  • Automate IFTA fuel tax reporting to eliminate the administrative burden of collecting state mileage and fuel receipts
  • Reduce human error and audit risk with complex calculations handled by the software

9. Support driver safety

Integrating the latest tools for implementing and monitoring driving behavior, you can improve driver safety too. The top GPS tracking solutions analyze, contextualize, and prioritize events to save time for safety departments, help you benchmark performance, and track impact of driver coaching.

10. Geofencing

Setting up a geofence perimeter on the GPS tracking tool helps you know when your vehicles enter or leave a predetermined area. This can reduce administrative burden, increase efficiency, simplify time and payroll management, improve compliance and fleet safety, and boost customer satisfaction.

Geofencing also works as an excellent anti-theft deterrent and increases fleet security with alerts for when vehicles go beyond approved routes and virtual boundaries.

11. Smarter maintenance scheduling

Integrating GPS telematics data into a fleet maintenance platform allows you to make data-driven maintenance decisions. Instead of relying on time-based or mileage-based maintenance schedules, fleet managers can use the tracking software’s odometer readings to prompt service reminders and alerts to ensure you stay on top of each asset’s preventative maintenance.
