Highlights

SimSENSOR enables sensor fusion algorithm testing in the lab by presenting Multi-GNSS and simulated MEMS sensor outputs to the bench environment. This approach gives you full lab control over every stimulus to the navigation algorithms — including GNSS pseudorange measurements from the receiver under test and emulated inertial outputs such as linear delta velocity and angular delta-theta. All inputs are precisely repeatable across test runs.

MEMS sensor modeling

  • Simulate up to four concurrent data streams from accelerometers, gyroscopes, magnetometers, compasses, and barometers

Comprehensive simulation

  • Generate sensor outputs consistent with any simulated trajectory
  • Access a built-in library of pedestrian trajectories with common "gestures"
  • Introduce noise and errors on an individual axis basis
  • Support a range of MEMS noise profiles

Sensor error and noise models

  • Apply deterministic and stochastic error models
  • Configure MEMS sensor Allan variance noise profiles
  • Model magnetometer, barometric, and digital compass behavior independently

Full flexibility

  • Meet specific commercial device R&D requirements
  • Build on existing Keysight GSS7000 / GSS9000 simulators

Ease of use

  • Deliver data as a UDP stream over Ethernet
  • Choose alternative delivery mechanisms (e.g., I2C, smartphone OS integration)
  • Control sensor parameters, noise, bias, and drift through a full GUI
