NAVION® highlights

Performant/affordable INS

NAVION® i2 is our highest-performing inertial navigation system (INS). It offers a great price-performance ratio and can be used in several navigational measurement applications.

RTK by default

The real-time kinematics (RTK) option on NAVION devices is turned on by default. RTK correction improves positioning accuracy down to 1 cm.

Dual antenna heading

Instant and accurate heading determination. With the two antennas included as standard, you have precise heading information within seconds while standing.

High-performance IMU

NAVION features an integrated MEMS-based IMU with gyroscopes, accelerometers, magnetometers, and pressure sensors. It can also work as a 9-degrees of freedom (DOF) IMU. The IMU-aided navigation reduces errors caused by GNSS outages.

Fast Ethernet connection

The Navion devices offer secure and fast data streaming via Ethernet communication interface to the PC running DewesoftX software.

Rugged IP68 device

NAVION i2 device features a very rugged design with IP68 standard protection. It is resistant to shocks, falls, and even water. It works in extreme environments and temperatures from -40 °C to +71 °C.

Flexible and distributable

Navion offers flexibility. Several NAVION® devices can be distributed and synchronized together over the ethernet connection or Dewesoft DS-WIFI wireless system without requiring additional PCs.

CAN bus output

NAVION® i2 features a CAN bus output port. Once the device is configured and initialized the unit can operate autonomously without connection to DewesoftX software. This makes it ready for integration into 3rd party systems.

PPS output

NAVION® i2 has a PPS synchronization port (via LEMO 4-pin connector) which can be used as the synchronization clock source for all other Dewesoft data acquisition devices.

External inputs

Additional RS232 input for RTK GNSS corrections with support of CMR+, RTCM 2.3, and RTCM 3.x. and a digital input for either odometer or brake pedal switch sensor.

A high-end inertial navigation system

NAVION® i2 is a great inertial navigation system for an affordable price. It is small, accurate, reliable, and rugged. This small device is all you need for accurate positioning measurements. It is bundled with dual-antennas and RTK support and works with various satellite constellations such as BeiDou B1, B2, and Galileo E1.

NAVION® i2 is an inertial aided-GNSS navigation system for providing accurate position, orientation, velocities, and accelerations. Measurements are estimated by a Kalman-based algorithm that combines Global Navigation Satellite System (GNSS) measurements with the measurements provided by a MEMS-based inertial measurement unit.

NAVION® i2 includes a high-precision GNSS sensor and a MEMS-based inertial measurement unit (IMU). The NAVION® i2 chassis is very ruggedized and complies with IP68 environmental protection standards. The device is well-suited for ADAS testing and vehicle dynamics tests.

NAVION® i2 will let you measure any moving object and provide accurate positioning even when the GNSS satellite reception is limited. The device is designed for applications where robust, continuous position, velocity, and heading navigation data are required.

NAVION® i2 also includes RTK (real-time kinematics) compatibility out of the box. RTK is used for even better position accuracy (down to 1 cm).

Great connectivity thanks to a connection box

NAVION® i2 inertial navigation system includes a break-out box that includes connection interfaces to PC running DewesoftX data acquisition software or to 3rd-party systems. The break-out box has standard connectors for:

  • Power supply

Synchronization With Analog, Digital, and Other Data Sources

Synchronization is the most important aspect of every test and measurement application. Without the right correlation of data, it's impossible to get correct or meaningful results.

Parameters from navigational devices like position, velocity, acceleration, altitude, pitch, roll, and heading are perfectly synchronized to the data from other Dewesoft data acquisition devices:

  • Analog (vibration, force, temperature, voltage, ...)

  • Counter and encoder (RPM, angles)

  • Video

  • CAN bus and CAN FD


  • Kistler KiRoad

  • Aerospace buses (IRIG Chapter 10, iNET, MIL-STD-1553, ARINC 429)

  • and other input sources supported by DewesoftX

The Dewesoft GNSS and INS devices can also provide exact time information for the synchronization of other devices.

Virtual 3D polygon

DewesoftX data acquisition software features a virtual polygon module for tests involving moving objects. It can visualize moving and static objects in a 3D virtual space. Polygon can also perform geometric measurements between multiple static or movable objects.

Polygon visualization and outputs can be calculated in real-time during the measurements or offline. It was specifically made for ADAS testing and vehicle dynamics testing but is far from being limited to just these two areas.

Processing mathematics of the virtual polygon module provides definable outputs:

  • Distance calculations (X and Y distance)
