From construction point of view Boom System is a mechanism based on the tubular boom technology which task is to extend the outboard magnetometer away from S/C main body. To be compliant with requirements for very compact and light solution tubular boom technology was used as the lightest possible design known to Astronika. Key features of the device are: long, 80 cm tubular boom of high positioning accuracy (both angular and linear) along with relatively high capacity cable container (up to 90 cm of 20 wires cable; designed and manufactured by Astronika as well), smooth deployment (speed of 5 cm/s), with the total mass of abt 150 g (excl. carried load) all in a small package of 92×45×46mm (including carried load). Non-explosive Lock & Release Mechanism features redundant solution using Dyneema wire cutters as baseline with peak power consumption of 4W. Onboard optical encoder provides the possibility to control deployment speed and distance as well as provide the opportunity for step-by-step deployment.
Device is based on previous developments, but particular project requirements were so specific and demanding that it can be considered a new technology. Astronika carried full development of the device from design, through manufacturing, integration, extensive test campaigns until delivery of the flight hardware in February 2021.
Device is already integrated in the Spacecraft and will be launched in July 2021.
