[QUOTE="CPP, post: 153381, member: 341"] [SIZE=6][B]StarFire™[/B][/SIZE] [attach=full]16490[/attach] [SIZE=4] The first of its kind, this global satellite-based augmentation system (GSBAS) provides five centimeter positioning accuracy on a worldwide basis, completely independent of geographical boundaries, allowing users to roam freely while maintaining the most precise positioning information. As the only GNSS manufacturer providing both GSBAS signal service and high-precision GNSS products of its own design, NavCom is able to offer custom solutions for unique customer applications.
