Loctronix Corporation, a provider of positioning, navigation, and timing (PNT) solutions for GNSS-challenged environments, has unveiled the HGX Interference Detection System (IDS) for identifying and monitoring intentional and unintentional interference sources. The IDS is being demonstrated September 10-11 at ION GNSS+ 2014, in Tampa, Florida.

“The IDS can detect sources of interference ranging between 5 dB and 60 dB GNSS jamming to signal (J/S) ratio. Featuring a novel profiling function, the IDS not only detects, but can identify the type of interference given a database of known/previously recorded profiles,” stated Michael Mathews, Loctronix’ CEO and founder.

According to Mathews, “The greater dependence of GNSS within critical infrastructure — including, transportation, communications, finance and the growing availability of jammers — requires new tools to respond to potential threats. The IDS is the first tool to combine the powerful capabilities of Loctronix Spectral Compression Positioning (SCP) technology for identification and characterization of signals with traditional GNSS signal processing to provide full situational awareness of GPS/GNSS operations. The IDS system will benefit government, military, and commercial/industrial applications wherever there is a critical dependence upon quality GNSS data.”

The IDS was developed using the Loctronix HGX hybrid sensor toolkit along with the company’s ASR-2300 ASR Workbench software defined radio platform. The standard implementation supports L1 GNSS bands and measurement rates of 10 measurements per second. Partner-licensed custom/solutions can support multiple bands (such as L2, L5) with greater bandwidths and measurement rates. Multiple sensitivity modes enable monitoring of sub-thermal and high-power interference.

The HGX toolkit API will be available for specialization of the system for custom/embedded applications and adaptation to other hardware platforms. Visit Loctronix in Booth 422.
