Inertial navigation, GNSS/INS, and state estimation

EULER-NAV provides engineering services around inertial navigation, GNSS/INS, and embedded sensor fusion. This is intended for teams that need focused senior-level support: on algorithms, architecture, debugging, replay and analysis workflows, or the verification-oriented engineering that makes navigation systems reliable.

EULER-NAV is led by Dr. Fedor Baklanov, who has 15+ years of experience in inertial and satellite navigation, state estimation, and safety-critical embedded systems.

What we do

  • Software / algorithm / hardware engineering around inertial navigation, GNSS/INS, and state estimation
  • “Boring” parts that make systems reliable: requirements engineering, system architecture, verification and validation

Why teams engage with us

  • They need senior navigation expertise for a limited time
  • Hiring takes time, but a technical decision or issue is urgent
  • They want a second opinion from someone who shipped safety-critical sensing systems before

Selected project examples

GNSS-free smartphone-to-vehicle alignment
A smartphone can be mounted in a vehicle in an arbitrary orientation, while many downstream functions need measurements expressed in the vehicle coordinate frame. We developed an inertial-only method to estimate the 3D rotation between the smartphone and the vehicle, without relying on GNSS during estimation. The solution was validated across real-world drive data and achieved below 15° heading-alignment error in most test drives.
Vehicle speed estimation without GNSS
Estimating vehicle speed from low-cost inertial sensors without GNSS is challenging because even small sensor errors accumulate rapidly. We developed a specialized post-processing solution combining an error-state Kalman filter with vehicle-motion constraints, standstill updates, and forward-backward estimation passes. On drive segments with sufficient vehicle dynamics, the estimated speed tracked the GNSS reference to approximately 5 km/h.
