Design, Fabrication, And Tuning Techniques Of Quadrifilar Helix Antennas For Small Satellites, Kelby Davis, Reyhan Baktur

Small Satellite Conference

Quadrifilar helix antennas are also called fractional turn helix is very appealing to spacecraft applications. A quadrifilar antenna offers circular polarization in its radiating hemisphere and its radiation pattern is not severely affected by a ground plane. These properties are important for closing the communication link and make the antenna relatively independent of the CubeSat frame and mounting location, which facilitates modular design of the antenna.

Although it has similar shape as a helical antenna, a quadrifilar helix antenna is fundamentally different. While there exists design theory and calculators for this type of antennas, detailed notes on design, fabrication, and …

Leo And The Big Blue Marble, A Bad Combination For Albedo Errors, Johan Leijtens, Hugo Brouwer, George Dimitriadis, Eric Bertels, Brian Tong Minh

Small Satellite Conference

Almost all satellites fly Sunsensors for launch and early orbit (LEOP) and safe mode operations. More than 90% of these are analogue Sunsensors with either an analogue or digital interface. The later are quite often referred to as digital Sunsensors but contrary to a true digital Sunsensor, analogue Sunsensors with a digital interface are still largely affected by albedo generated error signals.

Depending on the positioning of the sensor on the satellite, the satellites altitude, and the local node time, albedo errors can lead to significant measurement inaccuracies.

This paper describes some research into albedo induced errors in analogue fine …

Reuseable Orbital Transfer Vehicles: Why It Is The Future For Leo, Cislunar Space And Beyond, Roedolph Opperman, A. Drossler, Joseph Oorebeek, Victor Petitgenet, D. Buckley Biggs, Nathan Orr

Small Satellite Conference

The emerging Low-Earth-Orbit commercial economy brings exciting opportunities for technological innovation in space at unprecedented speed. This vibrant new commercial space age is disrupting the status quo, driving down costs, and revolutionizing general accessibility and sustained presence in LEO. Today, however, there is a reluctance in the space industry to embrace reusable spacecraft because of the perception of increased mission risk for no additional return on investment. This hesitation appears similar to the industry’s initial caution in adopting reusable launch vehicles in the early 2000s.

In this work we share our vision of the future: reusable orbital service vehicles (OSVs) …
