Company Profile: GPSat Systems Australia Pty Ltd

Through decades of collaborative research with prominent institutions—including over 30 years of partnership with UNSW Sydney and the University of Adelaide supported by Australian Research Council (ARC) Linkage grants—GPSat Systems has evolved from a systems integrator into an independent developer of advanced spatial AI and electronic spectrum protection systems.

Core Operational Domains

GPSat Systems divides its core business activities across three primary technical sectors:

1. Assured PNT & Electronic Warfare Defense

Recognizing that modern military and civilian operations are critically dependent on uninterrupted GNSS signals, the company engineers hardware and software layers designed to protect receivers against electronic threats. This involves deploying space domain awareness infrastructure and tactical anti-jam systems that maintain timing and position integrity in highly contested or gray-zone environments.

2. Spatial AI and Digital Twin Automation

For industrial and mining automation, the firm designs real-time 3D monitoring and coordination software. These systems enable multi-machine operations to run autonomously or semi-autonomously by constantly calculating physical spatial relationships to prevent collisions and map dynamic industrial environments.

3. Technical Consultancy & High-Fidelity Simulation

GPSat Systems provides complete lifecycle engineering, from modeling signal behaviors under extreme conditions to supplying precise RF test equipment for mission-critical hardware evaluation before field deployment.

Flagship Sovereign Technology: The GRIFFIN System

The cornerstone of GPSat Systems' proprietary technology portfolio is the GRIFFIN (GNSS Rf InterFerence FINder) system. Developed over multiple development phases supported in part by the Australian Defence Innovation Hub, GRIFFIN functions as an RFI radar network designed to secure physical spaces and flight paths against signal disruption.

System Architecture and Mechanism

The GRIFFIN system utilizes a decentralized network of hardware nodes deployed across a geographic area: * Sensor Nodes: Remote RF signal reception nodes that continuously scan the GNSS frequency bands for anomalous behaviors, power spikes, or structural signal deviations. * Central Coordinating Nodes: Networked hubs that collect synchronized wideband data from the sensor nodes. By using high-precision mathematical trilateration and time-difference-of-arrival (TDOA) algorithms, the system calculates the exact origin of a threat.

Deployment Applications and Capabilities

• Spatial Accuracy: GRIFFIN delivers pinpoint 3D geolocation down to an accuracy of a few meters over localized zones (e.g., small testing ranges, critical facilities), extending out to tens of meters across hundreds of square kilometers to protect wide aviation terminal approach corridors.
• Space Domain Awareness (SDA): The platform tracks Low Earth Orbit (LEO) threat TLEs (Two-Line Element sets) at scale, offering real-time clarity and attribution of electronic threats in gray-zone environments.
• Regional Networks: The company actively expands regional spectrum awareness networks, with multi-station operational deployments monitoring critical zones such as Melbourne Airport, Newcastle Ports, regional Victoria, and Twizel, New Zealand.
• Commercial Models:
  • GRIFFIN 1000: Optimized for civilian infrastructure including airport Ground-Based Augmentation Systems (GBAS), Automatic Dependent Surveillance-Broadcast (ADS-B) tracking, marine harbor pilot DGPS systems, and telecommunication or power grid timing networks.
  • GRIFFIN 2000: A multi-frequency, multi-constellation model designed for high-security environments and heavy industrial machine automation utilizing precise Real-Time Kinematic (RTK) positioning.

Distributed Product Lines

In addition to its proprietary GRIFFIN system, GPSat Systems serves as an established technology partner, reseller, and distributor for global leaders in precision positioning and simulation hardware, including Hexagon's NovAtel and Spirent Communications.

1. Anti-Jam Antenna Systems (NovAtel GAJT)

The company supplies commercial and military-grade GPS Anti-Jam Technology (GAJT) antenna systems that actively nullify interference signals: * GAJT-310 & GAJT-410: Low Size, Weight, and Power (SWaP) configurations designed specifically for smaller tactical platforms, uncrewed vehicles (UAVs), restricted military networks, and timing synchronization infrastructure. * GAJT-710: A heavy-duty, multi-constellation enclosure providing enhanced tracking, directional anti-jam performance, and direction-finding capabilities for land vehicles, marine vessels, and fixed installations.

2. GNSS Receivers & Combined GNSS+INS Systems

• OEM7 Series Receivers: High-precision card-level receiver elements and enclosed units featuring NovAtel Interference Toolkit (GRIT) software for spectrum analysis and digital filtering.
• SPAN Technology Systems: Integrated GNSS and Inertial Navigation Systems (INS) that combine satellite positioning with Inertial Measurement Units (IMUs). Systems like the CPT7 and PwrPak7-E1/2 provide continuous 3D position, velocity, attitude, and heading data even during brief satellite signal dropouts or severe canopy blockages.
• Tactical and Industrial IMUs: Distribution of high-performance MEMS and tactical-grade inertial sensors (such as the HG4930 or ISA-100C) configured to maintain spatial orientation in deep-subsurface or dense urban environments.

3. GNSS Simulation and Test Equipment (Spirent)

• Spirent GSS7000 Hardware: Compact, upgradeable multi-frequency multi-signal simulators that mimic real-world satellite constellations. These systems enable developers to stress-test navigation devices against evolving threats, multi-path errors, and atmospheric distortions inside a controlled lab setting.
• Record & Playback Systems: Hardware tools capable of capturing real-world RF environments in the field and playing them back bit-for-bit in laboratory environments to identify specific receiver vulnerabilities.

Specialized Engineering Services

1. Industrial 3D-SAM Automation

For heavy industries such as open-cut mining and automated bulk material handling, GPSat Systems deploys its 3D-SAM (Spatial Awareness Monitor) technology: * Digital Twin Coordination: Functioning similarly to real-time spatial physics engines, 3D-SAM tracks and coordinates the movements of heavy machinery across a shared digital workspace. * Deterministic Anti-Collision: Powered by spatial AI, the system evaluates real-time telemetry from multiple moving vehicles and static structures to implement autonomous machine braking or route deviation, ensuring collision-free operations. * Stockpile Mapping: Integrates 3D and 2D laser scanning data to track changing shapes and volumetric densities of raw materials and ore stockpiles in real time.

2. Technical Support & Fleet Rentals

To facilitate field trials, military exercises, and short-term infrastructure projects, the firm maintains an inventory of precision GNSS receivers, tactical IMUs, rugged enclosures, and high-precision tracking antennas available for commercial rental alongside dedicated technical support personnel.
