The S631 is Hemisphere’s multi-GNSS, multi-frequency
smart antenna powered by the Athena RTK engine. The
S631 provides robust performance and high precision
under canopy and near buildings. With multiple wireless
communication options and an open GNSS interface,
the S631 can be used in a variety of different operating
modes and applications. The S631 delivers centimeter-
level accuracy with virtually instantaneous intialization
times and cutting edge robustness in challenging
environments. With Bench-Mark’s technical support, the
S631 is incredubly easy to learn. All of our systems come
with training and support included, making any transition
as easy as possible. Check out our free training guides
