Protect PNT Infrastructure with the TimePictra® Platform and BlueSky™ GNSS Firewall
Watch our video tutorial that demonstrates the use of the TimePictra platform with BlueSky GNSS Firewall systems. This tutorial provides a comprehensive overview of the health of GNSS signal reception worldwide. It includes various scenarios on how to monitor, detect and analyze GNSS anomalies related to different GNSS metrics such as phase time offsets, position deviations and satellite count measurements.
Key Features
- Identification of GNSS system threats and protection from spoofing and jamming
- Seamless integration between existing GNSS antenna and GNSS system
- Optional Rubidium Miniature Atomic Clock (MAC) can be installed inside the unit
- 1 PPS and 10 MHz timing reference inputs for extended holdover (for example, connection of external cesium reference)
- Redundant AC or DC power options with power monitoring and load sharing
- Local and remote Command Line Interface (CLI) in addition to secure and easy-to-use web interface
- Embedded software is field upgradeable with new GNSS validation rules
- Seamless integration with TimePictra® software suite for end-to-end management of up to thousands of units from a single server

Using BlueSky™ GNSS Firewall's Validated and Hardened Outputs for GNSS Protection
Watch our video tutorial that demonstrates the use of BlueSky GNSS Firewall systems to learn how these systems can protect your critical infrastructure equipment. This tutorial provides a comprehensive overview of the use cases for the hardened and validated outputs from the BlueSky GNSS Firewall for the protection of critical infrastructure operations that are dependent on GNSS signals.
Additional Features
Achieve Level 4 Resilience
The DHS PNT Conformance Framework document describes four levels of resilience. These resilience levels build upon each other. For example, Level 2 includes all enumerated behaviors in Level 1. You can use the BlueSky GNSS Firewall as a stand-alone security barrier or in combination with our high-performance atomic clocks and timing distribution systems to achieve and exceed all four levels of resilience.
Secure Upgradeable Software
A programmable anomaly detector, which detects suspicious time and position inconsistencies, is at the core of the BlueSky GNSS Firewall. This detector validates the GNSS subframes for spoofing incidents based on defined data validation rules built into the BlueSky GNSS Firewall. New validation rules are added to every new BlueSky GNSS Firewall software release.
BlueSky GNSS Firewall's Performance Monitoring
Integrated within TimePictra software suite, BlueSky GNSS Firewall’s performance monitoring feature provides visibility into GNSS reception parameters across wide-scale deployments of the firewall. You can plot GNSS signal measurements, such as GNSS phase deviation, GNSS satellites in view and GNSS signal strength, for selected time periods to identify and isolate GNSS incidents quickly.
Optional MAC for Enhanced Threat Detection
Upgrading the BlueSky GNSS Firewall with the MAC enhances anomalous GNSS detection capabilities while also extending holdover performance of the hardened GNSS signal output for multiple days.
External Timing Reference
The 10 MHz or 1 PPS input allows you to connect autonomous references sources, such as our 5071B or TimeCesium® cesium clock products, to extend the holdover performance in case of a complete, long-term loss of GNSS reception.
Situational Awareness
Just as a network firewall detects and protects against network attacks, a GNSS firewall identifies jamming and spoofing threats and alerts transportation operations of untrusted sky-based signals.
Real-Time Jamming and Spoofing Protection
GNSS interruptions can be either unintentional or intentional. Adversaries may attempt to disrupt Position, Navigation and Time (PNT) solutions derived from GNSS in one of two ways:
- Spoofing, which makes a GPS receiver calculate a false position
- Jamming, which overpowers GPS satellite signals locally so that a receiver can no longer operate.
The BlueSky GNSS Firewall provides real-time protection against a wide range of these types of threats.
GNSS Threat Protection for All Critical Infrastructure
Critical infrastructure’s dependence on GNSS-based PNT continues to grow exponentially. Our BlueSky GNSS Firewall, in combination with network time protocol distribution, atomic clocks, timescale technology and software management and monitoring, provides a comprehensive solution for critical infrastructure operators.
