GPS Position Sensor

Create geospatial awareness. Use PASCO's GPS Position Sensor to collect GPS data simultaneously with other sensor measurements, automatically synching 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 My World GIS software 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.

Features

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.

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.
