SANTA CLARA, Calif. \u2013 Dec. 3, 2025 \u2013<\/strong> \u00a0SiTime Corporation, the Precision Timing company, today launched the Endura\u00ae temperature compensated oscillator (Super-TCXO\u00ae<\/em>), ENDR-TTT, for position, navigation and timing (PNT) applications. Engineered for superior holdover \u2013 uninterrupted operation when GNSS is not available \u2013 and resistance to jamming and spoofing, ENDR-TTT is an ultra-stable, low-power product for GNSS receivers in aerospace, defense, and industrial markets.<\/p>\n\n\n\n

\u201cSiTime\u2019s Endura Super-TCXO, ENDR-TTT, allows us to create a multi-layer anti-spoofing methodology,\u201d said Paul McBurney, GNSS expert, CTO and co-founder at OneNav. \u201cThe 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\u2019s ultra-stable reference clock.\u201d<\/p>\n\n\n\n

When GNSS signals are dropped due to unavailability or degradation\u2014including signal jamming or extreme environmental conditions\u2014holdover 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.<\/p>\n\n\n\n

\u201cSiTime\u2019s ENDR-TTT Endura Super-TCXO accelerates GNSS recovery by narrowing the resynchronization window, reducing spoofing and setting a new standard for ruggedized Precision Timing,\u201d said Piyush Sevalia, executive vice president of marketing at SiTime. \u201cOur latest product delivers a powerful combination of superior performance, low power, and small size, that leads the industry for PNT applications.\u201d<\/p>\n\n\n\n
