SiTime takes on GNSS threats
SiTime Corporation has launched the Endura® temperature compensated oscillator (Super-TCXO®), ENDRTTT, for PNT applications. 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 …
Moldova’s positioning system now uses Galileo
The MOLDPOS National Positioning System in Moldova has been integrated into the European Position Determination System (EUPOS), a pan-European GNSS augmentation service. The MOLDPOS navigational system uses both GPS and GLONASS, and now Galileo has been added. Creation of MOLDPOS was gradual. First, sites for placement of MOLDPOS stations …
