Sub-Surface Navigation (SsN)
Abstract
Building on technologies developed under the RSN program, the Sub-Surface Navigation (SsN) program provided the U.S. warfighter with the ability to navigate effectively underground, where the Global Positioning System (GPS) is unavailable. SsN also enables long endurance or covert underground missions where alternative navigation aids like inertial measurement units (IMUs) or inertial navigation units (INUs) are unsuitable. The SsN program uses specialized low frequency RF beacons and specially tailored algorithms to provide 3-dimensional navigation of personnel and mobile platforms underground. The greater strength and diversity of these signals provide coverage when GPS is denied due to lack of penetration through the earth. The SsN technology is available for transition to the U.S. Special Operations Command (SOCOM).
