In addition to positioning sensors we also offer DS-GYRO gyroscope for measuring pitch, roll and heading direction. 

Easy to Use

All Dewsoft GNSS interfaces work in a plug-and-play manner and are very easy to set up and use. Included DewesoftX software allows for easy device channel management and offers great visualization and analysis options for acquired data.

Dewesoft flexibility

Connect additional analog sensors (strain gauge, force, temperature, CAN bus, GPS, and countless other data sources) and measure additional parameters simultaneously, with all data perfectly synchronized.

Software included

Every Dewesoft data acquisition system is bundled with award-winning DewesoftX data acquisition software. The software is easy to use but very rich and deep in functionality. All software updates are free forever with no hidden licensing or yearly maintenance fees.

Enjoy our industry-leading 7-year warranty. Our data acquisition systems are made in Europe, utilizing only the highest build quality standards. We offer free and customer-focused technical support. Your investment into the Dewesoft solutions is protected for years ahead.

Reliable GPS navigation measurement

Dewesoft provides various GNSS-based receiver devices for the most precise position-based test and measurement applications. Our GNSS receivers are compatible with various satellite constellations to ensure the best signal coverage and the most precise and robust position tracking:

  • GPS L1 and L2

  • GLONASS L1 and L2



  • BeiDou B1 and B2

Severa GNSS receiver devices are available, either in stand-alone chassis or integrated into the heart of our data acquisition systems. Scroll further for different options available.

RTK support - Real-Time Kinematics correction for maximum positioning accuracy

Dewesoft GNSS instruments offer optional RTK (Real-time Kinematics) correction technology. RTK upgrade improves navigation accuracy down to 1 cm. It supports CMR+, RTCM 2.3, and RTCM 3.x GNSS corrections data. The RTK corrections data type is automatically detected. 

Dewesoft provides all hardware and accessories needed to establish the RTK setup:

  • RTK base station

  • RTK antennas

  • 3G and RF modems for data transmission between moving vehicles and base stations

Synchronization with analog and digital 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 results.

Parameters from navigational devices like position, velocity, acceleration, altitude, pitch, roll, and heading are completely synchronized down to microseconds to the data from other sources like CAN bus, analog (vibrations, deformations, flow), counter/encoder (RPM, angles), video, XCP/CCP, Kistler KiRoad, and others. 

The GPS and IMU devices provide exact time information that allows different devices to be perfectly synchronized even if they are on the other side of the globe. This is great for test scenarios with multiple vehicles. Dewesoft NET technology allows getting all data to a master vehicle fully synchronized.

100 Hz GNSS Receivers

GPS-VGPS-HS and DS-VGPS-HSC GNSS receivers are GPS-based USB GNSS receiver devices for precise position, speed, and displacement measurement.

Devices are equipped with the latest GPS technology with 100 Hz GPS-based speed and displacement sensors. The result is a high-dynamic GPS receiver and an easy-to-use speed/distance sensor with high bandwidth. In addition to this, no calibration drives for different road conditions (ice, water, snow, off-road) are needed.

Main features

  • Real 100 Hz GPS engine

  • Portable and rugged construction

  • Insensitivity to the road surface (can be used on mud off-road, water, snow, ice,..)

  • No calibration is required

  • Easy-to-install and easy-to-use

  • Supports differential GPS (SBAS) as a standard function

  • Mark input for brake trigger switch

  • Data over USB or COM with zero latency PPS sync

  • CAN output (DS-VGPS-HSC)

GPS clock provider and GNSS receiver

The DS-GPS-CLOCK uses a 10 Hz GNSS sensor and can be used for simple positioning measurement applications as well as for synchronization of Dewesoft data acquisition systems.

The DS-GPS-CLOCK is a synchronized time base generator capable of using either GPS or IRIG as a time source. This allows completely synchronized data acquisition of multiple systems whether they are mobile or stationary. Additionally, the DS-GPS-CLOCK can also be used as an IRIG time code generator (output IRIG B/DC) synchronized to the GPS time.

The base of any GPS receiver is precise time measurement. In addition to the position information, a precise PPS (pulse per second) is generated by the GPS engine. This pulse is used to synchronize a 40 MHz oscillator with software PLL (phase-locked loop). The result is an ultra-stable 40 MHz clock source that is completely free of drift over time.

EtherCAT® GPS synchronization junction

EtherCAT® GPS synchronization junction device is used similarly to synchronization junction for synchronization between USB and EtherCAT®-based data acquisition devices but by using GPS as a time source.

ECAT GPS junction has a built-in 10 Hz GPS receiver and connector for connecting GPS or IRIG-B-DC time code signal. The devices are synchronized using this time code.

The built-in GPS receiver can also be used for recording positioning information, just like with any other Dewesoft GNSS navigational device.

Embedded GNSS receiver for SBOX processing computers

Our SBOX data processing computers can optionally be equipped with 10 Hz or 100 Hz GNSS receivers for precise positioning measurement. The embedded GNSS sensors can be integrated into the following Dewesoft systems:

The embedded GNSS receivers (100 Hz version) offer the same navigational and accuracy capabilities as our standalone 100 Hz DS-VGPS-HS/HSC units.

GPS Display

Bright, small, rugged LED display accessory is available for the drivers that can be used inside the vehicle. The display can be directly connected to any of our GPS devices and will display:

  • Speed

  • Heading

  • Altitude

  • Time

  • The number of satellites in reach

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.

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)

  • Angle calculations

  • Gate cross triggers

  • Time and time reset

  • Radius calculations

GPS and inertial navigation applications

We provide a total solution for advanced position-based test and measurement applications. DewesoftX software received multiple innovation rewards, including software innovation of the year by Automotive Testing Technology International magazine, and serves as a one-stop software for all navigational tests.
