Phased Helical Antenna Array For Cubesat Application, Kameron Lacalli
Phased Helical Antenna Array For Cubesat Application, Kameron Lacalli
Undergraduate Honors Theses
CubeSats communication links are typically slow due to their power and size restrictions. However, a low power, high speed down link connection can allow for greater data collection and relaying, pushing the capability of 1U CubeSats beyond what is traditionally thought possible. Investigated here is the feasibility of a 11 Mb/s down link connection on a 1U CubeSat, accomplished via 2x2 helical antenna phased array operating on the 802.11 standard. Using a phased array also allows for beam steering to secure connection with the ground station when the on board ADCS may not provide precise pointing capability of the CubeSat, …
Design Of An Integrated Acceleration Acquisition Subsystem To Satisfy High-Speed And Low-Area Requirements For Cubesats, Ryan J. Rumsey
Design Of An Integrated Acceleration Acquisition Subsystem To Satisfy High-Speed And Low-Area Requirements For Cubesats, Ryan J. Rumsey
Master's Theses
Cal Poly San Luis Obispo’s PolySat team is designing the Multipurpose Orbital Spring Ejection System (MOSES) in order to record acceleration data during the launch of CubeSats as well as to provide GPS coordinates to locate the position of CubeSats once they are injected into orbit. This work focuses on the design and development of the acceleration data acquisition (DAQ) subsystem of MOSES. This subsystem is designed around the need for a high-speed sampling system of at least 200 kHz across four channels of data, plus low-area limitations in the MOSES form factor which is roughly half the size of …
