Vernier GPS Sensor (VGPS, discontinued)
Specifications and User Guide

Troubleshooting
– Primary Test: Make sure your software and computer operating systems (as applicable) are supported by the Vernier GPS (see requirements below). Connect the Vernier GPS to the USB port on and original LabQuest or your computer. If using a computer, use the USB extension cable (included). Go outside with an unobstructed view of the sky, and wait for enough satellites to be acquired. The first time could take up to 5 min (or 30 min with an original VGPS).
