Protected Innovation, Shared Knowledge
We patent what protects our business and publish what advances the field. Our IP portfolio reflects serious work — not patent theater.
Intellectual Property
Phasar Labs holds and has filed patent applications covering advanced signal processing methods for GNSS positioning. Our IP portfolio reflects core work in carrier-phase ambiguity resolution, phase calibration, and noise-tolerant processing architectures.
Single Epoch Phase Ambiguity Resolution and Ranging
A patent covering methods for single-epoch carrier-phase ambiguity resolution and precise GNSS positioning.
Realtime Phase Calibration
A patent application covering methods for removing antenna and hardware phase bias from GNSS signals in real time.
High Resolution DFCW Radar
A patent application covering a technique that uses novel range ambiguity resolution to produce high-resolution interferometric range solutions.
Additional Patent Applications
Further patent applications are pending, covering related signal processing improvements and integration techniques. Specific titles and abstracts remain confidential pending examination and review.
Publications
Where our IP strategy permits, we contribute validated results to the academic and professional GNSS community. A complete bibliography is available upon request.
