On the detection and tracking of space debris using the Murchison Wdefield Array. I. Simulations and test observations demonstrate feasibility by Tingay, Steven, Kaplan, D.L., McKinley, B., Briggs, F., Wayth, Randall, Hurley-Walker, N., Kennewell, J., Smith, C., Zhang, K., Arcus, W., Bhat, Ramesh, Emrich D., Herne, D., Kudryavtseva, N., Lynch, M., Ord, S.M., Waterson, M., Barnes, D.G., Bell, M., Gaensler, B.M., Lenc, E., Bernardi, G., Greenhill, L.J., Kasper, J.C., Bowman, J.D., Jacobs, D., Bunton, J.D., Desouza, L., Koenig, R., Pathikulangara, J., Stevens, J., Cappallo, R.J., Corey, B.E., Kincaid, B.B., Kratzenberg, E., Lonsdale, C.J., McWhirter, S.R., Rogers, A.E.E., Salah, J.E., Whitney, A.R., Deshpande, A., Prabu, T., Udaya Shankar, N., Srivani, K.S., Subrahmanyan, R., Ewall-Wice, A., Feng, L., Goeke, R., Morgan, E., Remillard, R.A., Williams, C.L., Hazelton, B.J., Morales, M.F., Johnston-Hollitt, M., Mitchell, D.A., Procopio, P., Riding, J., Webster, R.L., Wyithe, J.S.B., Oberoi, D., Roshi, A., Sault, R.J., Williams, A.

“…The imaging capabilities of the MWA can be used to simultaneously detect multiple pieces of space debris, image their positions on the sky as a function of time, and provide tracking data that can be used to determine orbital parameters. …”

Surveillance of Space with Passive Radar using the Murchison Widefield Array by Hennessy, Brendan

“…Using FM radio as the transmitter source, the MWA is able to surveil a large volume of space to detect and track satellites, space debris and other objects in orbit. This thesis covers orbital-specific signal processing methods for radar product formation, as well as orbit determination, and culminates in an Australia-wide observation campaign.…”

A roadmap for the Australian space industry to contribute to global societal challenges by Flentje, Warren, Clayfield, Kimberley, Held, Alexander, Pearce, Sarah, Crosby, Philip

“…Australia also offers an excellent location for tracking space objects including space debris and threats from Near Earth Objects. A new Roadmap from the national science agency introduces some major opportunity themes consistent with the Agency’s priority areas, along with technology developments in each - enabling business, research and infrastructure investments that can contribute to progress. …”

Limits on radio emission from meteors using the MWA by Zhang, X., Hancock, P., Devillepoix, H., Wayth, R., Beardsley, A., Crosse, B., Emrich, David, Franzen, T., Gaensler, B., Horsley, L., Johnston-Hollitt, M., Kaplan, D., Kenney, D., Morales, M., Pallot, D., Steele, K., Tingay, S., Trott, C., Walker, M., Williams, A., Wu, C., Ji, J., Ma, Y.

“…We also report detections of other transient events, such as reflected FM broadcast signals from small satellites, conclusively demonstrating the ability of the MWA to detect and track space debris on scales as small as 0.1 m in low Earth orbits.…”

Self-deployable sail for CubeSat de-orbiting mission: preliminary design and demonstration of PANDORA by Syaril, Azrad, Yeong, Lit Yang

“…Since the 1960s, the launching of satellites has increasingly caused the Earth's orbit to be filled with space debris travelling at very high speeds. To mitigate this problem, in 2007, the Inter-Agency Debris Coordination Committee (IADC) created a specific guideline to suggest every spacecraft, including satellites, to de-orbit itself within 25 years after the end of its mission within the Low Earth Orbit (LEO). …”

Transmissive solar sailing by Thompson, Samuel

“…These sails are also amongst the most sustainable orbit control systems, being associated with reduced satellite weight, mission cost and space debris footprint. However, they also have weaknesses that constrain how and where they can be used --- most notably, their poor performance in low Earth orbit (LEO), where the majority of satellite missions occur. …”
