The research with Institute of Science, Tokyo, reveals DMU41 is well suited to LEO missions

After announcing a research partnership in April of 2024, Silicon Sensing and the Institute of Science, Tokyo, have now completed a test program evaluating the performance and durability of the DMU41 tactical-grade inertial measurement unit (IMU) in radiation environments similar to those found in space.

The results show that the DMU41 continues to perform well even when exposed to cumulative radiation doses as high as 10 kRad, which exceeds the usual radiation levels encountered during small satellite missions in Low Earth Orbit (LEO).

Testing of a large sample of DMU41 IMUs took place at the Institute of Science Tokyo’s Wakasa Wan Energy Research Centre in Fukui City. The program evaluated Single Event Effect (SEE) and Total Ionizing Dose (TID) on DMU41 units. SEE verified resilience to ionizing particles, while TID assessed long-term reliability under radiation.

All testing used dose and exposure levels at or above key industry standard thresholds—much harsher than normal operational conditions at LEO.

The DMU41 is a robust, 9 degrees of freedom, high performance IMU. It operates in temperatures ranging from -40oC to +85oC, delivering outstanding low noise performance, bias instability and angle random walk.

Offering performance comparable to typical fiber-optic gyro IMUs, it comes in a far more compact package—measuring just 50.5×50.5x51mm, weighing under 180g and consuming less than 1.8W. The DMU41 is designed to streamline system integration and help satellite developers shorten their certification process.

David Somerville, General Manager, Silicon Sensing, said, “This is an important partnership for us, and these are strong results for our IMU. In this fast-evolving sector performance, size, endurance, power consumption – and cost – are all crucial and these results validate the choice of DMU41 by a growing number of satellite manufacturers. We are confident our technology will significantly improve LEO operations.”

Amazon’s broadband-by-satellite service Project Kuiper says it will have broadband coverage in five countries by March 2026.

Ricky Freeman, president of Project Kuiper’s Kuiper Government Solutions division at Amazon, speaking at the Novaspace World Space Business Week event in Paris, told delegates that his firm would have more than 200 satellites in orbit by the end of this year. Kuiper is due to launch 27 craft on September 25th which will be added to the 102 already in orbit.

Freeman said that his greatest problem today was securing rocket launches, and said that if he could buy a slingshot that was powerful enough “I’d probably buy it!”

Kuiper is on a strict ITU-mandated deadline where it has to have half of its initial 3,232 satellites in orbit by July 2026. A second constellation of an additional 3,200 ‘next-gen’ satellites would then follow with 54 countries covered by 2028.

Since April, operational Kuiper satellites have launched aboard two Falcon 9s and two Atlas 5s. Freeman outlined “another launch in October, and another November-December to have approximately 200-plus satellites by the end of the year — not exactly where we wanted to be, but again, making great progress.”

There’s good news from the satellites already in orbit with Freeman saying that downlink speeds are reaching 1.8 Gb/s and uplinks to the satellite of 450 Mb/s.

He stressed that by the end of Q1 2026 the constellation will have a continuous coverage through and be able to offer services for the US, Canada, UK, Germany and France. By the end of 2026, he said Kuiper would be available in about 26 countries.

The service plans to be live in 54 countries in 2027, and up to 100 countries by the end of 2028.
