Additional Features
Achieve the Highest Level of PNT Resilience
The IEEE® P1952 standard outlines resilience levels for equipment used for Position Navigation and Timing (PNT). The BlueSky GNSS Firewall 2200 enables designers of systems for critical infrastructure to achieve the highest degrees of resilience, including the requirements outlined in Level 5 of the P1952 standard.
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.
Data Visualization With TimePictra Software
TimePictra software provides data visualization for BlueSky technology’s GNSS observables and SkyWire technology’s clock comparison measurements. Organizations can configure, monitor and visualize the health of their timing infrastructure to achieve a higher level of timing security and resilience. The software’s dashboard allows users to view GNSS threats detected by BlueSky technology and clock alignment verification by SkyWire technology all on the same screen.
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.
Fortifying Network Management
To enhance the security provided by the BlueSky GNSS Firewall, the network management interface must meet the increasingly stringent security requirements of critical infrastructure. In addition to providing robust protection against live-sky jamming and spoofing threats, the BlueSky GNSS Firewall now features a highly secure Trusted Time network management interface, further enhancing its defense against cyber threats.
BlueSky GNSS Firewall with SkyWire Technology
SkyWire technology utilizes GNSS signals as a virtual wire, instead of a timing source, to enable precise time comparison between geographically separated locations. It provides a cost-effective connection to ensure traceability to an authoritative time source.
