argus-02-link-budgets

Argus-02 will characterize the performance of modern electronics in the space environment. Argus-02 is a reflight of the Argus-01 mission, which was lost in the launch failure of ORS-4 Super Strypi. It is owned and operated by Saint Louis University (Michael Swartwout, KE6YNJ, responsible operator). The primary mission of Argus-02 is to characterize the effects of space radiation on modern SRAM. Argus-02 has a secondary mission to investigate the ability of on-board software and a commercial imager to detect natural events such as auroras and lightning strikes.

The satellite will be turned over for integration August 9, 2019, and launched as a secondary payload aboard NG-12, from Wallops Flight Facility, on or about October 19, 2019, and carried to the ISS as cargo. It will deploy from the ISS around January 2020. Transmission will begin 30 minutes after deployment, and cease 12 months later. Atmospheric friction will slow the satellite and reduce the altitude of the orbit, until de-orbiting occurs about 18 months after launch.

The spacecraft is a single unit (1U) 10 cm X 10 cm X 11.35 cm CubeSat module. The total mass is about 1.1 Kg.

Below are the link budgets for uplink and downlink. This link budget was created using the spreadsheet developed by Jan A. King, W3GEY/VK4GEY. It is available here.
