Which Type of Data Is Collected by GPS?

Global Positioning System (GPS) technology has become an integral part of our lives. From navigation in our cars to tracking fitness activities on our smartphones, GPS plays a crucial role in providing accurate location information.

But have you ever wondered what type of data is collected by GPS? In this article, we will explore the various types of data that GPS collects and how it impacts our daily lives.

Location Data

At its core, GPS is designed to collect location data. It uses a network of satellites orbiting the Earth to determine your exact position on the planet’s surface.

This location data is typically represented using latitude and longitude coordinates. By triangulating signals from multiple satellites, GPS receivers can calculate your position with remarkable accuracy.

Time Data

In addition to location data, GPS also collects time data. Each satellite in the GPS constellation has an onboard atomic clock that provides highly precise timing information. The receiver uses this time data to calculate the distance between itself and each satellite by measuring the time it takes for signals to travel from the satellites to the receiver.

Velocity Data

GPS can also collect velocity data, which refers to the speed and direction of movement. By continuously tracking your position over time, GPS receivers can calculate your velocity by analyzing changes in your location. This information is particularly useful for applications such as sports tracking, navigation systems, and vehicle speed monitoring.

Elevation Data

In addition to horizontal positioning, GPS can also provide elevation data. This refers to the height above or below a reference point like sea level. Elevation data is crucial for activities such as hiking, mountain climbing, aviation, and surveying.

Satellite Data

GPS receivers can also collect data about the satellites themselves. This includes information about the satellites’ orbits, health status, and signal strength.

By analyzing this data, GPS receivers can determine which satellites are in view and their respective signal quality. This information helps improve the accuracy and reliability of GPS positioning.


GPS collects a wide range of data to provide accurate location information. From location and time data to velocity, elevation, and satellite information, GPS technology enables a multitude of applications that rely on precise positioning. Understanding the types of data collected by GPS helps us appreciate its significance in our daily lives.
