The S621 GNSS receiver is powered by Athena RTK technology. With Athena, S621 provides state-of-the-art RTK performance when receiving corrections from a static base station or network RTK correction system. With multiple connectivity options, the S621 allows for RTK corrections to be received over radio, cell modem, Wi-Fi, Bluetooth, or serial connection. S621 delivers centimeter-level accuracy with virtually instantaneous initialization times and cuttingedge robustness in challenging environments.
The S621 receiver also enables users to work with Atlas. Atlas is Hemisphere’s industry-leading global correction service, which can be added as a subscription to the S621. Atlas delivers world-wide centimeter-level correction data over L-band communication satellites. With Atlas, S621 users are able to experience sub-decimeter positioning performance anywhere on earth, without the need to be near a GNSS or communication infrastructure.
