Agreement between two International newspace pioneers will enable tiny satellites to operate in large flocks

SANTA CLARA, Calif., June 4th, 2020 (Momentus PR) — Momentus (www.momentus.space), provider of in-space transportation services for satellites, and OrbAstro, a UK company focused on developing the technology to enable tiny satellites to operate in large flocks, announced today a launch contract to fly a 3U to SSO onboard the SpaceX Dedicated rideshare mission in 2021.

This in-orbit demonstration mission on a 3U OrbAstro platform will host a variety of payloads:

An Ultrascale+ based onboard computer, 10X more powerful than the current state-of-the-art in Zynq 7030 based systems, coupled to an Artificial Neural Network based constellation management system.An Electrical Power System with a novel battery chemistry, allowing typically a 5X increase in mission lifetime compared to conventional Li-ion chemistries for a given volume and mass.A compact ADCS allowing for fast steering and accurate pointing, tailored for precision formation-flight.A new type of thermal management system, allowing kW-class payloads to operate on nanosatellite-class platforms at a compelling duty cycle.

Smallsat flocking is relevant to existing and emerging markets in newspace. OrbAstro believes there is much needed room for improvement in constellation-level efficiency, so the new company is ...
