PASPORT GPS Position Sensor - PS-2175

Move to Wireless!

Recommended Alternative — The Wireless Weather Sensor with GPS can perform all of the functions of the PASPORT GPS Sensor at the same price while also providing all the major environmental measurements if desired. Best of all, it connects directly* to your computers, tablets, smartphones and Chromebooks without the need for an interface and with no cables to get in the way.

*Devices without native Bluetooth® Smart connectivity will require a low cost USB adapter - see the product page for details.



Create geospatial awareness. Use PASCO's GPS Position Sensor to collect GPS data simultaneously with other sensor measurements, automatically synch the data to your latitude, longitude, altitude, and velocity.

Two Modes

Absolute Position Mode: Pinpoints your location in the world and reports the latitude and longitude within a resolution of 2 meters. Then this data can be imported into Google Earth (see the video below) to overlay all your sensor data on maps or aerial photos.

Relative Position Mode: This special mode enables a higher resolution (0.2 meters) suitable for physics experiments involving bicycles or people running or walking. This mode is used for motion experiments in which the position in the world is not required.

Typical Applications

  • Analysis of the motion and energy of large-scale moving objects (person, car, skydiver, bicycle, boat, etc.)
  • Provide spatial information for mapping other sensor data (temperature, water quality measurements, etc.)


The GPS Position Sensor measurements include:

  • Latitude and longitude
  • Elevation
  • Velocity (speed and bearing)
  • Number of satellites tracked

Additional Features

The GPS Position Sensor is dependable

  • Velocity is obtained by Doppler from the satellites, not by the calculation of position data.
  • The highly sensitive receiver is able to track satellites even under tree canopies.
  • An LED indicator indicates whether the GPS Position Sensor is able to triangulate its position.


  • PASPORT Sensor Extension Cable
  • How It Works

    The GPS Position Sensor uses the Global Positioning System maintained by the U.S. government. The system consists of more than 24 satellites that broadcast ranging signals and other necessary data. For the Position Sensor to determine its own position and velocity, it must receive data from at least three satellites. When the sensor is first powered on, it searches the sky for available satellites. This process typically takes between 30 seconds and 2 minutes. Once satellites have been identified, the sensor actively tracks them and acquires new satellites as they come into view.
