The micro-Broadband Receiver (uBBR) on the Very-Low-Frequency Propagation Mapper (VPM) CubeSat | CU Experts

The Very Low Frequency (VLF) Propagation Mapper (VPM) is a 6U CubeSat; designed to measure VLF radio waves in Low-Earth Orbit. The science; goals of the VPM mission are to measure VLF signals broadcast by the DSX; mission, and to study natural and anthropogenic signals (from lightning; and VLF transmitters) in the near-Earth space environment. The primary; payload consists of an electric field dipole antenna deployed to 2; meters in length, and a magnetic search coil deployed 50 cm from the; spacecraft. Signals from these two sensors are conditioned by analog; electronics, sampled, and then processed digitally into downloadable; data products. The VPM mission was launched in January 2020; science; operations began in March 2020 and continued through September, when; contact with the spacecraft was lost. This paper describes the mission; goals and instrument designs in detail, as well as some examples of the; VPM dataset.
