Bliley Technologies

Bliley Technologies is an Erie, Pennsylvania-based US manufacturer of precision frequency control products, founded in 1930. The company specializes in oscillators (OCXO, TCXO, VCXO, XO), quartz crystals, and frequency synthesizers for demanding applications including space, military, and industrial markets.

For space applications, Bliley produces radiation-hardened and radiation-tolerant frequency control products qualified for satellite and launch vehicle use. Their space-grade oscillators are designed to maintain frequency accuracy under radiation exposure, temperature extremes, and vibration conditions typical of the space environment. Products include space-grade OCXOs (oven-controlled crystal oscillators), TCXOs (temperature-compensated crystal oscillators), and custom frequency solutions for LEO, MEO, and GEO satellite missions.

Bliley works with satellite manufacturers and prime integrators to supply timing and synchronization components for communications satellites, Earth observation satellites, and defense platforms. Their products serve as precision frequency references for satellite transponders, navigation systems, and timing subsystems.
