Radiation-tolerant COTS atomic clock for commercial space introduced by Microsemi

Microsemi Corp. in Aliso Viejo, Calif., is introducing the commercial off-the-shelf (COTS) radiation-tolerant SA.45s commercial space chip scale atomic clock (CSAC) for low-Earth-orbit (LEO) space applications. The device provides the accuracy and stability of atomic clock technology with reduced size, weight, and power consumption (SWaP), and is for satellite timing and frequency control; satellite cross linking; assured position, navigation and timing; and Earth observation. The CSAC provides drift performance and built-in 1-pulse-per-second input for working together with the global positioning system (GPS). The timing module is a s a stand-alone atomic clock with a 10 MHz CMOS-compatible output. For more information contact Microsemi online at www.microsemi.com.
