Overview

Introducing the xNAV650 Inertial Navigation System

Despite combining the latest MEMS inertial sensor technology with survey-grade GNSS receivers, the xNAV650 INS is also our most competitively priced INS to date.

With hardware bundles starting at under ?8000, the xNAV650 provides surveyors with reliable and precise navigation data ? even when budgets are limited.

Small form factor, incredible accuracy

Measuring only 77 x 63 x 24 mm the xNAV650 is our smallest INS to date. Its small form factor is ideal for any application where space is limited making it ideal for UAV-based mapping.

When weight is a factor look no further than the xNAV650 INS. Weighing just 130 g, the xNAV650 is the ideal partner when precision is crucial, but the payload needs to be as light as possible. A lighter payload and lower power consumption means longer flight times for UAVs.

Quad constellation (GPS, GLONASS, BeiDou and Galileo) as standard means that users of the xNAV650 INS can benefit from 2 cm position accuracy even in the most challenging GNSS environments.

Simple set-up, easy to use software

The xNAV650 INS benefits from optional Precision Time Protocol (PTP) time stamping functionality. All xNAV650 INS devices have the option to utilise PTP when synchronising time with LiDAR and other sensors that also utilise the feature. PTP allows for a much simpler set-up over ethernet, providing surveyors with the ability to get up and running quickly.

OxTS’ gx/ix tight-coupling technology ensures that users of OxTS inertial navigation systems receive the most accurate measurements possible even in tough GNSS conditions such as urban canyons.

OxTS Georeferencer allows users of OxTS’ inertial navigation systems to georeference pointclouds from almost any LiDAR sensor. By combining OxTS INS data with raw LiDAR data using OxTS Georeferencer, users can increase the quality of their pointclouds, decrease the time to survey, intelligently analyse data and improve project ROI.

OxTS NAVsuite software is a complimentary addition to OxTS’ range of inertial navigation systems including the xNAV650. The tools allow users of OxTS’ devices to configure and post-process data with ease.

Models

xNAV200

The xNAV200 is a small GNSS/INS system which is ideal for all size and weight constrained applications. The system is designed to deliver superior position, roll/pitch and heading data even in challenging operating environments. 4 GB of on-board storage is available, allowing four days’ worth of measurements to be stored internally. The xNAV200 logs data during capture which can then be easily downloaded from the system and post-processed using our advanced software, which is included as standard at no extra cost.

xNAV250

The xNAV250 GNSS-aided INS is ideal for users requiring maximum performance on a tight budget. The xNAV250 uses the same survey-grade dual frequency GNSS receivers and custom MEMS IMU as the xNAV550, for centimetre-level position accuracy and precise orientation and true heading. The only difference is the xNAV250 is a logging only solution allowing users to download data from the system and post-process it with our advanced post-processing software, which is included free of charge.

xNAV500

The xNAV500 is a compact, lightweight GNSS-aided inertial navigation system, perfectly suited for all applications where size and weight as well as performance matter. It measures and outputs position (50 cm), heading (0.15°), roll/pitch (0.05°) and much more in real-time. Your data can also be post-processed later with our advanced software suite, included free of charge. It is ideal for use on UAVs and other weight constrained applications.

xNAV550

The xNAV550 integrates dual L1/L2 GNSS receivers for 2 cm RTK position accuracy. The improved receivers also mean better heading accuracy. The xNAV550 is 5 mm taller than the other models and slightly heavier at 425 g to accommodate to bigger receivers, but still matches the other models for length and width and features the same IP65 rated anodised aluminium enclosure.
