Space-qualified high precision clocks for ​global navigation satellite systems​. ​ 

Features

  • High stability of 2 × 10-12 at τ = 1 second.

  • Low power operation: ≤ 14 W basic clock at +45°C baseplate, ≤ 39 W steady-state with BTC, and ≤ 65 W during warm-up.

  • Low drift aging: ≤ 1 × 10-13/day at BOL and ≤ 5 × 10-14/day after 1 year of continuous operation.

  • High reliability with 700,000 hours MTBF.

  • Fully space-qualified, radiation hardened, with negligible environmental sensitivities (temperature, magnetic, voltage, barometric).

  • Compact and lightweight: 5.0" × 8.5" × 6.0" and < 14 lb.

Benefits

  • Unparalleled stability and minimal drift deliver precise, dependable time and frequency reference for demanding space applications.

  • Very low sensitivity to temperature, magnetic field, radiation, voltage, and barometric pressure minimizes environmental error and flicker floor.

  • Integral baseplate temperature controller maintains performance across panel temperatures for improved stability and reduced temperature sensitivity.

  • Radiation-hardened RF output path and overall design support phase-continuous operation through transient radiation events for mission resilience.

  • Low power, small size, and low mass help conserve spacecraft power and payload budgets.

  • Fast warm-up (≤ 1 hour to ± 2 × 10-10) enables quicker readiness after power cycling or initial activation.​
