NAVION® i2 functionality and features

NAVION® i2 inertial navigation system measures the vehicle’s GNSS position, accelerations, and angular velocities. A Kalman-based algorithm combines GNSS and IMU measurements and provides high accuracy and stability. The built-in IMU sensor has very low drift and helps to maintain position determination even in case of incorrect measurements due to multipath or when the GNSS signal is weak. A GNSS outage of 10s will only cause up to 30cm error.

Main features of NAVION® i2 INS:

• High-accuracy 100 Hz GNSS receiver (1.2 m horizontal and 1.9 m vertical positioning accuracy).

• Built-in MEMS-based inertial measurement unit (IMU) with accelerometer, gyroscope, magnetometer, and pressure sensor.

• Electronic circuit performing the Kalman filtering.

• Support for GPS (L1, L2, L5), GLONASS (L1, L2, L3), BeiDou (B1, B2), Galileo (E1), AltBOC, E5a, E5b, NavlC (IRNSS) L5 satellite constellations.

• Dual-antennas are included by default.

• RTK (Real-time kinematics) support.

Measured parameters

NAVION® i2 inertial navigation system provides several output channels:

• Latitude, longitude, and altitude.

• Orientation (roll, pitch, and heading).

• Velocities and angular velocities.

• Body accelerations.

• Slip angles.

IP68 protection in a rugged chassis

The NAVION® i2 inertial navigation system is built-in a sealed compact and robust chassis. NAVION® chassis is certified with IP68 environment protection and is prone to outside elements such as wind, water, mud, and dust. It can be used in practically any weather condition.

NAVION® i2 device is also highly resistant to high vibration, shocks, and falls. It complies with the MIL-STD-810G standards.

NAVION® i2 is also designed and rated to work in extreme temperatures. It is tested and certified to operate at -40 °C to +71 °C.

The device offers easy-mount vehicles on any type of surface with included suction cup attachment. The suction cups will securely mount the device even to vehicles moving at higher speeds.

Applications Navigation for Any Industry

Navion devices provide accurate position, velocity, acceleration, and orientation under the most demanding conditions. Devices are designed to meet the needs of navigational applications across various industries such as automotive, aerospace, railway, marine, agriculture, transportation, industrial equipment, and robotics.

Common applications:

• Vehicle dynamics testing

• Autonomous vehicle testing - ADAS

• Autonomous Underwater Vehicles - AUVs

• Unmanned Aerial and Ground Vehicles - UAVs and UGVs

• Durability testing

• Flight dynamics

• Precision agriculture

• Surveying and mapping

• Platform control

• Motion compensation

DS-IMU1 Compact Inertial Navigation System

If you need a very small and compact inertial navigation system, then we offer DS-IMU1. It still offers great accuracy in a very small form factor. The DS-IMU chassis is only 3 x 4 x 4.5 cm (1.18 x 1.57 x 1.73 inch).

DS-IMU1 still provides a reliable GNSS-aided inertial navigation including AHRS that provides accurate position, velocity, acceleration, and orientation. It offers up to 100 Hz data rate with USB and RS232 data interface. It features PPS output for synchronization using GPS PPS signal.

DS-IMU1 inertial navigation system is a device in a ruggedized chassis with an IP67 degree of environmental protection and  MIL-STD-810G rating. 

DS-IMU1 applications

• Synchronization and timing with Dewesoft data acquisition systems

• Simple positioning

• Brake test

• Acceleration test

• Orientation of different objects

• Simple vehicle dynamics test

• Simple lane change test

• Circle drive

• Simple ADAS tests

Interactive map visual control

The DewesoftX DAQ software offers real-time 2D and 3D map visual control. The map visual control offers a built-in interactive GPS map via Open Street Maps. Several layers of map tiles are available:

• Out-of-the-box satellite imaging with open-source OpenStreetMap layers hosted on Dewesoft’s map servers.

• Support for custom tile and WMS layers as well as georeferenced images.

• No manual alignment is required.

• 2D, 3D, and terrain display modes with standard, 1st, or 3d person camera options.

• Online or offline support. Images can be pre-downloaded for offline usage.

• Support of multiple layers with individually configurable opacity levels.

• Channel-based trace coloring with various color schemes.

• Ability to display multiple GPS signals on one widget.

• 3D model widget for yaw, pitch, and roll monitoring.

The mapping widget works no matter the GNSS/IMU hardware used. It works with any Dewesoft GNSS receiver or inertial navigation hardware. The widget also works with 3rd party supported INS hardware such as OxTS, Genesys ADMA, or if you get navigational data through CAN or other supported interfaces.
