Rpwi mechanics rwi sensor design

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 mechanics rwi sensor design

Early activities

  • Two types of tapes:

  • Diameter: ø25mm

  • Thickness: 0.15mm

  • Mass: ~100g/m

  • Diameter: ø15mm

  • Thickness: 0.1mm

  • Mass: ~50g/m

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 mechanics rwi sensor design

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
