What We Do

Revolutionizing how satellites know where they are

NaviGate develops an advanced onboard solution for autonomous satellite navigation and guidance. Our system integrates seamlessly with satellite hardware, processing GNSS data, radiometric observables, and other measurements in real-time.

As the number of satellites in orbit grows, ground-based navigation becomes economically and operationally unsustainable. NaviGate eliminates that dependency, enabling spacecraft to determine their own orbit and maneuver autonomously.

Core Technology

Built for the next generation
of space operations

Scalable, adaptable, and sensor-agnostic, our onboard navigation software works across mission profiles and orbital regimes.

Multi-Sensor Fusion

Flexible architecture processes GNSS, inter-satellite, optical, and other measurement types, adapting to available sensor payloads.

Real-Time OD & Guidance

Precise orbit determination and guidance computation onboard, with no dependency on ground-segment interventions.

Plug-and-Play

Designed as a drop-in module that integrates seamlessly with existing satellite hardware and mission architectures.

Constellation-Ready

Scales from single satellites to large constellations, supporting inter-satellite navigation and cooperative orbit determination.

Multi-Orbit Support

Operates across LEO, MEO, GEO, and deep-space mission profiles with dynamically reconfigurable navigation models.

Cost Reduction

Minimizes ground-segment operational costs by eliminating the need for continuous Earth-based tracking and commands.

Our Approach

From problem to solution

Built with a clear vision: make autonomous navigation accessible to every satellite mission.

Why

The Problem

With the increasing number of satellites in orbit, relying on ground-based support for navigation operations is becoming economically and operationally unsustainable, especially for low-cost missions.

How

Our Method

We enable autonomous navigation and guidance through a highly adaptable onboard software that analyzes available data in real-time, processing multiple measurement types without ground dependency.

What

The Product
