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

• GALILEO E1

• COMPASS L1

• 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.

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.

DS-VGPS-CLOCK
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.

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:

• SBOX data processing computer

• SBOX Waterproof data processing computer

• R1DB/R2DB portable data acquisition systems

• R2 data acquisition systems

• R4 data acquisition systems

• R8 data acquisition systems

• R8DB data acquisition 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.

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.
