In response to the growing global incidents of GNSS jamming and spoofing, Honeywell has harnessed its extensive expertise in GNSS and integrated navigation to develop a comprehensive suite of monitors aimed at safeguarding against GNSS interference. One key aspect of this suite is the integration of Honeywell's inertial sensors, which enables the detection of spoofing attacks while maintaining operation during jamming events. Additionally, Honeywell has created a series of monitors designed specifically for GNSS receivers, capable of identifying a wide array of spoofing attempts. Moreover, spoofing detection and protection algorithms have been incorporated into our Flight Management System (FMS) and Enhanced Ground Proximity Warning System (EGPWS) platforms.
The Honeywell inertial spoofing detection suite comprises six monitors that leverage inertial measurements with observations from GNSS and other sensors to detect GNSS anomalies. These components are fully integrated into the Honeywell Laser Ref VI. Beyond detecting spoofing, this inertial monitor suite allows for uninterrupted navigation during jamming and spoofing incidents while offering a mechanism to identify the end of and recover from spoofing conditions.
Honeywell's GNSS-based spoofing detection suite also consists of six monitors: a GNSS receiver clock bias monitor, a GNSS time misalignment monitor, a position change monitor, a zero-velocity monitor, a barometric altitude monitor, and an ephemeris monitor. By operating at the source of GNSS observations, these monitors efficiently detect spoofing attacks and send alerts to downstream systems.
Furthermore, Honeywell has incorporated spoofing protection into our FMS and EGPWS devices. These systems utilize all available sensor inputs to identify anomalies in GNSS outputs indicative of spoofing. Given that each platform has its unique set of sensors, the spoofing monitors are designed for flexible integration of available resources.
This paper will delve into the details of the monitors and protection schemes, presenting operational testing results from various scenarios, including laboratory tests, organized jamming and spoofing event testing (such as APEX and Jammertest), and flights through regions known for interference.
