The Spectratime Force 2020 Rubidium clock is designed for the defense market. Spectratime, a provider of high precision atomic clocks and a business of the Orolia Group, has launched the Force 2020. The Force 2020 is a rugged, anti-vibration, GPS/GNSS-lockable, ultra-low-noise Rubidium atomic clock for highly dynamic defense platform applications. According to Pascal Rochat, managing director of Spectratime, “Next-generation defense airborne radars, drones, helicopters, secure shipboard and radio communications systems use high K-band frequencies which require ultralow noise performance. In tactical missions, ultra-low-noise performance can only be minimally degraded during exposure to dynamic vibration and high-g environments to maintain the integrity of the battlefield systems. Spectratime’s Force-2020 rubidium atomic oscillator is perfect for such critical applications, and thus we are currently working with large defense contractors to integrate our new product into their highly dynamic defense platform systems.” Product features Output frequency up to 500 MHz Can use 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 1-ns resolution State-of-the-art frequency and timing signal stability performance Integration of an ultra-low-noise OCXO oscillator with optional low g-sensitivity and a single or dual vibration-isolated tray for the OCXO and/or the Rb oscillator to meet various dynamic application requirements.
