Description

The xNAV family of inertial navigation systems from OxTS combine GNSS technology with high performance miniature inertial sensors to deliver a complete navigation solution in a lightweight package.

Key features

• Low weight – from just 365g including rugged anodised aluminium enclosure

• Dual GNSS receivers – stable heading performance in all conditions

• Survey grade GNSS – L1 only DGPS or L1/L2 RTK position

• Tactical grade IMU – 0.05° roll/pitch accuracy • No export control – ship and operate worldwide with zero hassle

• gx/ix™ technology – tight coupling and inertial relock maintain performance in harsh GNSS environments

• Excellent value – unbeatable price/performance with antennas and software included free

• Powerful post-processing and analysis tools – free NAVsuite software gives you complete control over your data

• Model variants to fit your budget – choose options and extras to suit your application or simply upgrade later
