Xsens MTi-680 RTK-GNSS/INS

The Xsens MTi-680 represents the highest standard in GNSS/INS when connected to an RTK receiver. The MTi-680 supports RTK accuracy, which means you get access to smooth, high frequency (400Hz), centimeter-level accuracy in position even in GNSS-denied environments.

As a part of the MTi 600-series, this module is lightweight, robust and cost-effective.

MTi-680G RTK-GNSS/INS

The MTi-680G RTK-GNSS/INS rugged module includes a full-featured internal RTK receiver, which enables cm-level accurate positioning, sub 0.5deg orientation estimates, a rugged IP68 rated housing, as well as a very small form factor at an industry breaking price point.
