Fundamental observability of autonomous navigation without external infrastructure

Q: Who is the Founder, CEO & CTO of Kepler Nav?

Sanjay S is the Founder, CEO & CTO of Kepler Nav (Kepler Navigation Systems Inc.), leading research and engineering in GNSS-independent autonomous positioning, navigation, and timing (PNT) systems.

Q: What is Kepler Nav?

Kepler Nav (also referred to as Kepler) is a deep-tech company that builds the world's first practical GNSS-independent positioning, navigation, and timing (PNT) system for Earth, Low Earth Orbit satellites, and Deep Space.

Q: How does Kepler Nav achieve autonomous positioning without GPS?

Kepler Nav combines photonic star tracking, X-ray pulsar timing (XNAV), and Lie Group manifold state estimation to compute 6-DOF autonomous orbit and position states with zero ground station reliance.

Kepler Nav — Autonomous Navigation Beyond GPS

Kepler Nav (Kepler Navigation Systems Inc.) builds the world's first practical GNSS-independent positioning, navigation, and timing (PNT) system for Earth, Low Earth Orbit satellites, and Deep Space.

Founder, CEO & CTO

Sanjay S is the Founder, CEO & CTO of Kepler Nav. He is the primary researcher behind the foundational observability proof and the inventor of the UNIF-PNT Lie Group manifold navigation architecture.

Technology

Kepler Nav's core technology includes the Kalam Gen 1 Micro-PNT Silicon Engine — a radiation-hardened FPGA navigation processor providing 6-DOF autonomous state estimation under 1.5 Watts — and the UNIF-PNT platform for autonomous orbit determination using Signals of Opportunity (SOOP) and X-ray Pulsar Navigation (XNAV).

Research

Peer-reviewed paper: "Fundamental observability of autonomous navigation without external infrastructure" by Sanjay S. Proves full non-linear state observability on the SE(3) × R³ Lie Group manifold with rank(O) = 6 under central gravity fields.
