A-SHIELD

A-Shield

Resilient Positioning for Critical Applications

A-Shield is ANavS®’s advanced solution for resilient real-time positioning, offering unmatched protection against GNSS interference such as jamming, spoofing, and meaconing. Built upon our tightly coupled sensor fusion engine and extended with AI-driven threat detection, A-Shield ensures trusted navigation – even under criticle conditions.

Robust. Intelligent. GNSS Resilience by Design

A-Shield was designed for industries where positioning integrity is critical:

UxS Navigation in Urban and GNSS-challenged Environments
Railway and Infrastructure Monitoring
Autonomous Driving (ADAS, V2X)
Critical Mobile Assets (Defense, Emergency Services)
Maritime and Port Operations

Key Features

Multi-layer GNSS protection against spoofing, jamming, and meaconing
Tightly coupled GNSS/IMU/Odometry sensor fusion
Galileo OSNMA authentication for verified satellite signals
AI-enhanced threat detection with Recurrent Neural Networks (RNN)
Navigation with protection levels and confidence indicators
Robust hardware – optimized for high-reliability environments
SLAM/visual Navigation for redundant localization

System Architecture

Sensor Fusion Engine: GNSS/INS/Odometry
AI Module: Neural network for threat classification
OSNMA Handler: Galileo authentication verification
Web Interface: Configuration, visualization, remote access
Cloud Backend (A-Hub): Postprocessing, integrity logging, fleet monitoring

Technology Stack

A-Shield combines multiple layers of resilience (excerpt):

Layer 1 – Classical Interference Detection

AGC analysis, C/N0 monitoring, Hatch filter
OSNMA authentication (Galileo)
Carrier-phase and cross-band analysis

Layer 2 – AI-Based Interference Classification

RNN trained with real-world data (e.g., from Jammertest 2024)
Multi-label classification of signal threats per GNSS band
Deep neural networks fuse GNSS, IMU, and RF signal metrics

Layer 3 – Redundant Sensor Fusion

Visual odometry, LiDAR SLAM or Camera SLAM
Radio navigation or landmark-based fallback localization

These are integrated in the ANavS® Sensor Fusion Framework, which guarantees real-time, high-precision positioning with output integrity values.

Breakthrough Pricing

Most attractive value for money with a performance that competes with the top manufacturers.

Minimal Warm-up time

The warm-up time is only 1-2 minutes and no dynamic running-in procedure is required. Automatic recognition of the heading immediately after starting the vehicle.

ACOM Data Stream

The ACOM data stream is compatible with the NCOM data stream and can be connected directly to the OxTS toolchain without changing the toolchain.

ROS 2

ROS-2 simplifies the integration of real-time data.

Company | ANavS | Munich | Made In Germany | Future of Positioning | PPP | Navigation | HAS Technology

HAS Technology (Galileo's High Accuracy Service)

Galileo's HAS technology makes it possible to achieve PPP free of charge by sending correction data directly via the Galileo satellites. This technology significantly improves the accuracy of GNSS systems and is particularly useful for applications that require high precision.

Company | ANavS | Munich | Made In Germany | OSNMA

OSNMA (Open Service Navigation Message Authentification)

OSNMA is a technology that is already integrated in the ANavS products and is used for the algorithm to ensure the authenticity of navigation data. It is a security function to ensure that navigation data is not manipulated or spoofed.
