Mission will validate miniaturized low earth orbit microwave sounder operation from an advanced nanosatellite bus

Oxfordshire, England, December 3, 2018 – Orbital Micro Systems (OMS), a leader in advanced
instrumentation for small satellite missions and weather intelligence analytics, has announced it is
partnering with NanoAvionics, an innovation leader in nanosatellite bus and flight-proven subsystem
technologies, to conduct a rideshare mission to fly one of OMS’s miniaturized passive microwave
sensors. The mission will utilize the NanoAvionics M6P 6U satellite bus.

“OMS is delighted to work with an industry leader such as NanoAvionics in deploying an additional
passive microwave sounder,” said William Hosack, chief executive officer for OMS. “The M6P is quickly becoming the gold standard for flexible bus solutions. It provides a high degree of reliability which enables us to deliver better weather data collection technology. This advanced bus architecture will help us accelerate our activities and enable us to quickly expand into multiple vertical and geographic markets.”

OMS is on track to launch multiple weather observation satellites in 2019. This mission will carry a
humidity and precipitation monitoring sensor that will enhance the company’s data collection
capabilities. These important atmospheric parameters play a role in decision-making, affecting many
industries.

NanoAvionics’ innovations in bus technology include a green propulsion system, reliable avionics and
control systems, and multiple transmission options. The M6P bus provides up to 5U of payload capacity which can be segmented for multiple systems or applications with compatible orbital requirements.

“Our goal at NanoAvionics is to provide a highly functional and reliable satellite bus which innovative
payload developers such as OMS can utilize to deliver space-based applications quickly and frequently,” said Vytenis Buzas, CEO of NanoAvionics. “Space missions leveraging our services and buses can become much more economical for participants in shared missions through distributed launch costs.”
