Sentence examples for ramp errors from inspiring English sources
The general configuration of the simulator allows the user to select either static or dynamic fault profiles including both step-wise (instantaneous) and ramp errors.
One also expects the quality of the inertial sensors not to play a significant role for the FDE algorithm performance, at least for the step GNSS errors, although the performance could be different for the cases of ramp errors.
The second approach detects the slowly growing (ramp) errors by considering the GPS measurements over a relatively long period (up to 30 minutes) and using KF innovations averaged over 2.5, 10 and 30 minutes.
Step-wise faults simulate measurement additive faults (e.g. signal multipath) while the ramp faults correspond to slowly-varying cumulative errors (e.g. satellite clock drift), although the ramp errors are not addressed within the present work due to requirement of equivalent modifications of RBE-based FDE approaches.
Note that GNSS ramp errors are often considered to be far more challenging compared to step errors as the latter generate instantaneous jumps in the measurement biases and can be relatively easy detected both via consistency check or by comparison to the actual output of inertial integration.
In the processing we have largely removed bias and ramp errors by using ground control points (GCPs).
The authors in [12] used a GNSS ramp error model (GNSS pseudorange error, which constantly grows at a particular rate starting from zero error) and evaluated two IM strategies: solution separation method and extrapolation method.
Gremlin's platform provides something of a sandbox for engineers to slowly ramp up errors, and then more importantly, ramp down errors if a breakage is detected.
Then, a novel active RIS is proposed to alleviate the ramp gain error.
This paper, for the first time, quantitatively analyzes the ramp gain error in the ramp-input stage (RIS) that is the crucial component in such ADC, and verifies it using behavior model simulation.
Delaying the start of the TVG ramp may reduce the error.
