SiTime Takes on GNSS Threats, Unveiling Jamming- and Spoofing-Resilient Precision Timing Solution

SiTime Corporation, the Precision Timing company, 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. 

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,” said Piyush Sevalia, executive vice president of marketing at SiTime. “Our latest product delivers a powerful combination of superior performance, low power, and small size, that leads the industry for PNT applications.”
