About
The NewSpace Master Reference Oscillator (MRO) is a Space Subsystem that generates and distributes highly stable and reliable frequency signals. It is suitable for LEO, MEO, and small GEO satellites with a lifetime up to 12 years. The MRO is specifically designed for telecommunications, navigation, and earth observation applications where frequency stability, ultra-low phase noise, and low power consumption are crucial. It provides up to 4 outputs with highly stable frequencies at 100 and 200 MHz, generated from an ultra-stable oscillator. The MRO achieves a long-term stability of ±200 ppb over a 12-year lifetime. Short-term stability is ensured by the intrinsic OCXO performance, and long-term stability is guaranteed by a microcontroller that disciplines the oscillator on a GNSS PPS signal. Advanced algorithms ensure smooth synchronization while avoiding glitches or jumps in the frequency. The subsystem is Single Point Failure (SPF) free, with nominal and redundant functions fully isolated. It can be used in cold and hot redundancy. The MRO includes a DC/DC converter, On/Off telecommands, PPS input/outputs via RS422, a CAN communication bus, and all necessary telemetry for reliable monitoring and operation. It is based on a modular architecture for ease of assembly, integration, and customization. Product quality adheres to the highest industry standards, with components chosen according to AECQ-100/200 criteria and active components undergoing radiation testing for every lot. This compact MRO is an ideal solution for lightweight devices with a small footprint.
