Flexible instruments

DEWESoft offers flexible navigational instruments for tracking position with different accuracy levels and frequency rates suitable for almost any test & measurement application. All instruments are perfectly synchronised to analog data of other DEWESoft instruments.



GNSS Satellites


GNSS SATELLITES

Tracking of GPS L1/L2/L5, GLONASS L1/L1, BeiDou, WAAS, EGNOS, MSAS, GAGAN, QZSS and optionally RTK positioning

Synchronisation


Synchronisation

Possibility to synchronise navigational data with analog data from other DEWESoft products (SIRIUS, DEWE-43, KRYPTON, MINITAURs)

High Acurracy


RTK high accuracy

Positional accuracy down to 1 cm with usage of Real-time Kinematic GNSS technology (RTK)



Inertial Measurement Units


DS-IMU2


IP68 rated
MIL-STD-810G environmental protection
500Hz data output rate (DS-IMU2)



DEWESoft inertial measurement units are ruggedised and reliable GPS aided inertial navigation systems including AHRS that provides accurate position, velocity, acceleration and orientation under most demanding conditions.

DS-IMU1 and DS-IMU2 USB instruments are ruggedised combination of gyroscopes, accelerometers, magnetometers and pressure sensors with a GNSS receiver.

Inertial sensors are coupled together with GNSS receiver in a sophisticated fusion algorithm to deliver accurate and reliable navigation and orientation.

GNSS receiver supports GPS, GLONASS, BeiDou, GALILEO, WAAS, EGNOS, Gagan and Real-time kinematic - RTK.

Both DS-IMU1 and DS-IMU 2 offer fast and easy installation with plug and play SW functionality.
