Work

  • Sigma Point Labs — Autonomous Navigation R&D

    Sigma Point Labs is a small R&D company focused on estimator reliability for autonomous navigation. We study the failure modes that appear when GPS is unavailable, sensing is degraded, or standard filters report confidence that no longer reflects operational error. Our role is not to replace an autonomy team’s stack. It is to help characterize where the estimator becomes fragile, where uncertainty becomes misleading, and where additional validation is needed before higher-risk deployment.
