GNSSIMUDaten

GNSSIMUDaten refers to the combined data stream originating from a Global Navigation Satellite System (GNSS) receiver and an Inertial Measurement Unit (IMU). GNSS systems, such as GPS, GLONASS, Galileo, and BeiDou, provide absolute positioning information by calculating a receiver's location on Earth based on signals from satellites. An IMU, on the other hand, measures acceleration and angular velocity using accelerometers and gyroscopes, respectively. These inertial sensors provide relative motion data, allowing for dead reckoning and the estimation of orientation.

The fusion of GNSS and IMU data is a common technique in navigation and positioning systems. GNSS provides accurate, albeit sometimes infrequent or temporarily unavailable, absolute position fixes. IMUs provide continuous, high-frequency measurements of motion and orientation, which are crucial for bridging gaps in GNSS coverage, such as in urban canyons, tunnels, or during satellite signal outages. The integration of these two sensor types leverages their complementary strengths. GNSS data can be used to correct for drift in the IMU's inertial measurements over time, while IMU data can smooth out GNSS position jumps and provide a more robust and continuous trajectory estimate. This combined data is essential for applications requiring high-precision, reliable navigation, including autonomous vehicles, drones, robotics, and surveying.
