10-9 STABILITY CLASS OCXO | NEWSPACE SOLUTIONS Issue: A1, 51003083.110. 14 May 2024 Specifications are subject to change without notice Copyright © 2022 to 2024, Rakon Limited. All rights reserved Page 1 of 4 Contact Us RK409AVNS The RK409AVNS is a compact NewSpace Ultra-Stable Oscillator (USO) that delivers 10 -9 class frequency stability. Its Allan Variance ( AV) achieves a short -term stability of 2.5 E-13 at tau 1 s, providing exceptionally high performance. The frequency stability is ±0.2 ppb (over operating temperature -10 to 60 °C under vacuum). The superior short-term stability makes the RK409AVNS well -suited f or telecommunications, Low Earth Orbit (L EO), Global Navigation Satellite Systems (GNSS) and Precision Navigation and Timing (PNT) payload requirements.
