Spectratime Force-2020 Rugged Disciplined Rubidium Oscillator

  • Force-2020 Rubidium Oscillator

Force-2020 Oscillator Overview

The Force-2020 is a new, smart, low cost, rugged, low g-sensitivity, anti-vibration, ultralow noise, very high frequency, compact GPS/GNSS-disciplined Rb oscillator clock module (SynClock+ GPSDO).

It outputs frequency up to 500MHz. The Force uses the patented SmarTiming+® technology, disciplining an external SAASM or a non-SAAMS GPS or GNSS 1PPS reference up to 100,000 seconds with an auto-adaptive loop time operating at 1ns resolution based on the GPS/GNSS reference noise and jitter level, providing state-of-the-art frequency and timing performance. Additionally, it integrates an ultralow noise OCXO with optional low g-sensitivity and a single or dual vibration-isolated trays for the OCXO and/or the Rb oscillator, depending on the application requirements. The Force is well suited for highly dynamic defense platform applications, including tactical helicopter and ground/airborne radar, UAV/UGV drone (Unmanned Aerial Vehicle and Unmanned Ground Vehicle), shipboard, and secure ground/air radio communications and mobile satcom systems.
