RPWI Team Meeting – Warszawa, 10-11 January 2011 RPWI Mechanics: RWI sensor design Marta Tokarz
NanoSpace -1 satellite Possible 1÷1.5m long antenna with similar weight Length of only 25-30cm The advantages of use of a tubular boom on the nanosatellite RPWI Team Meeting – Warszawa, 10-11 January 2011
Early activities • Two types of tapes: • Diameter: ø25mm • Thickness: 0.15mm • Mass: ~100g/m • Diameter: ø15mm • Thickness: 0.1mm • Mass: ~50g/m Material: spring stainless steel RPWI Team Meeting – Warszawa, 10-11 January 2011
Beryllium bronze tubular booms • Present solution: • Diameter: ø6mm • Thickness: 0.05mm • Mass: ~8g/m • Max tubular boom length: 1.5m • In developing: • Diameter: ø10mm • Thickness: 0.07mm • Mass: ~15g/m • Max tubular boom length: 2÷2.5m RPWI Team Meeting – Warszawa, 10-11 January 2011
RWI – An orthogonal tri-axial antenna system • Smooth deployment • Small mass of 375g including: • - 3x 1.5m dipoles • - deployment unit • - 3x pre-amplifiers • Motor power consumption during deploymentshould notexceed 2W RPWI Team Meeting – Warszawa, 10-11 January 2011
