Terrestrial auroral science and radio interferometric
technology demonstration.

Description

Technology demonstration mission in a polar orbit that will advance our ability to perform radio interferometry using CubeSats in space. This mission is a technical pathfinder that leverages the Auroral Emission Radio Observer (AERO) CubeSat project by duplicating that satellite in a build-to-print manner. VISTA will launch at the same time as AERO. The experiment will use the two CubeSats in orbit and combine them with ground-based beacons and receivers to demonstrate the performance advantages of Vector Sensor Interferometry relative to conventional approaches.
Terrestrial auroral science and radio interferometric technology demonstration. The AERO and VISTA CubeSats both host vector sensing antenna systems providing advanced electromagnetic capabilities. Together, they will provide the first in-space demonstration of interferometric imaging, beamforming, and nulling using electromagnetic vector sensors at low frequencies (100 kHz – 15 MHz). A key goal of the joint missions’ technology demonstration is to validate theoretical sensor performance modeling indicating that interferometric arrays composed of vector sensors will be able to maintain sensitivity even in the presence of terrestrial interference. If validated in flight, this capability would relax the requirement that space-based low frequency interferometers be placed far from the Earth (e.g. lunar orbit), and the closer communications range will significantly increase the data volume returned from space-based radio telescope systems.

VISTA’s objectives, achieved in concert with AERO, are:
1) Validate algorithms for, and sensitivity advantages of, vector sensor interferometry;
2) Apply vector sensor interferometry to auroral radio emissions; and
3) Perform a survey of the low frequency RFI environment in low Earth orbit to assess the suitability of the environment for future multi-element interferometric constellations.
