Breakthrough LEO Space Applications Use CSAC
The number and variety of Low Earth Orbit (LEO) space applications for small satellites is growing rapidly, with commercial, scientific and defense payloads. Their applications—such as alternative PNT, optical time transfer, inter-satellite communications, RF geolocation, earth observation and interferometry—all require low Size, Weight and Power (SWaP) precision timing solutions. Microchip’s space Chip Scale Atomic Clock (CSAC) was the industry’s first commercially available radiation-tolerant CSAC, delivering the accuracy and stability of atomic clock technology with significant SWaP reductions.
