The NewSpace MRO (Master Reference Oscillators) is a piece of modular equipment for applications requiring high stability and reliable signal. It is a part of Rakon’s NewSpace Equipment series suitable for Low Earth Orbit (LEO), Small GEO satellites and satellite constellations with a lifetime guarantee of up to 12 years. The NewSpace MRO is specifically designed for LEO broadband, GNSS and Earth Observation applications where precision frequency stability, ultra-low phase noise and low power consumption are crucial. It achieves a highly stable long-term frequency stability of ±200 ppb over 12 years. Frequencies are available from 10 MHz to 1 GHz with up to two different output frequencies. For applications need higher frequencies from 1 up to 30 GHz, our Master Local Oscillators (MLOs) are compatible with the high-end frequency spectrum. The current baseline includes an integrated DC/DC converter, which allows the clock to be powered directly from the primary satellite bus, an ON & OFF TM/TC and two outputs @10 and 100 MHz. The key functions of synchronising to a GNSS 1PPS signal, frequency distribution and electronic frequency control have been qualified. These features can be optionally integrated to customise the MRO according to application configurations. Testing and screening flows can be tailored according to customer requirements to reduce cost and lead-time  Power bus: 28 or 50/75 V  Typical phase noise @10 MHz -110 dBc/Hz (@1Hz) -137 dBc/Hz (@10Hz) -150 dBc/Hz (@100Hz) -158 dBc/Hz (@1kHz) -160 dBc/Hz (@floor)  Overall frequency stability: ±200 ppb for 12 years
