Introduction

Global Positioning System (GPS) has been available to the public since 1983. This networking system of satellites has proved itself to be a valuable tool for positioning, self-guidance, data collection, and even games on phones. However, all of these applications are created with the assumption that the receiving antenna has a clear view of the satellites above. Due to this assumption, the average GPS antenna is not created with the ability to collect signals or reject noise while under snow. Our project's intent is to design an antenna with greater signal gain as well as better noise suppression than standard GPS antennas when covered in snow.

Motivation

GPS has potential for multiple uses. If signals could be collected in locations with excess snow, a whole new field of applications open up to snow related studies, hobbies, and weather reporting. A few examples of applications are:

  • Positioning

    • Avalanche rescue/retrieval

  • Signal correction for antennas covered in snow

    • Base antennas -- Tectonic Plate measurements

    • Real Time Kinematic (RTK) Stations

  • Reporting on snow properties
