SiTime adresserer GNSS sikkerhedstrusler
Til brug i GNSS-systemer lancerer SiTime timingløsning, som er modstandsdygtig over for jamming- og spoofing-angreb (in english).
Dette er en prøve. SiTime Corporation hs launched the Endura temperature compensated oscillator (Super-TCXO), ENDR-TTT, for position, navigation and timing (PNT) applications. Engineered for superior holdover – uninterrupted operation when GNSS is not available – and resistance to jamming and spoofing, ENDR-TTT is an ultra-stable, low-power product for GNSS receivers in aerospace, defense, and industrial markets.
- SiTime’s Endura Super-TCXO, ENDR-TTT, allows us to create a multi-layer anti-spoofing methodology, says Paul McBurney, GNSS expert, CTO and co-founder at OneNav, and he continues:
- The first layer minimizes the search window, preventing spoofing because signals outside the window are never tracked. The second layer addresses exceptionally large search windows, such as in first acquisition, where spoofers can be tracked. In this case, the spoofer signals can be identified and removed due to SiTime’s ultra-stable reference clock.
When GNSS signals are dropped due to unavailability or degradation - including signal jamming or extreme environmental conditions -holdover maintains timing stability locally to enable uninterrupted network operation. The ENDR-TTT Endura Super-TCXO provides up to 20x longer holdover and 20x better PNT accuracy, dramatically improving spoofing resistance.
- SiTime’s ENDR-TTT Endura Super-TCXO accelerates GNSS recovery by narrowing the resynchronization window, reducing spoofing and setting a new standard for ruggedized Precision Timing. Our latest product delivers a powerful combination of superior performance, low power, and small size, that leads the industry for PNT applications, says Piyush Sevalia, executive vice president of marketing at SiTime.
