“…On-board orbit determination -We have developed a solution for autonomous orbit determination for CubeSat in deep space cruise (Segret 2019 [13], [14], 2021 [15]). Several teams also work on the development of autonomous navigation solutions, especially because of the likely rise of deep space CubeSats, as stand alone or accompanying probes.…”

Optical navigation on a CubeSat must rely on the best extraction of the directions of some beacons from on-board images. We present an experiment on OPS-SAT, a CubeSat of the European Space Agency (ESA), that will characterize an onboard algorithm to this aim, named Angle-based Correlation (AbC). OPS-SAT is a 3-unit CubeSat with an Attitude Determination and Control System (ADCS) and an imager that have proved their reliability with typical performance at CubeSat scale. We selected a few star-fields that all present enough visible stars within a 10 • field of view. When our experiment is run, OPS-SAT is pointed to the most convenient star-field at that time. There, the star-field is imaged and subwindows are extracted from the image around the expected location of each star, based on the attitude-quaternion reported by the ADCS. The AbC reconstructs the absolute direction of the central body, in principle unknown, which is the pointed known star in the experiment. The method intensively uses the quaternion algebra. The beacon location is first consolidated in the field of view with the AbC. Then, the field of view is finely positioned against the sky, again with the AbC. A covariance is associated with the found beacon direction. Our experiment with OPS-SAT manages the pointing and the imager, and processes the taken images. Then, it downloads the on-board computed absolute directions and their covariances, to be compared with the actual directions. After a campaign of intensive use of the experiment, the statistical performance of the algorithm will be established and compared to the on-board computed covariances. As a bonus, an assessment of OPS-SAT's inertial pointing stability will be available. The AbC can theoretically get rid of the Attitude Control Error (ACE) of the platform and of the Attitude Knowledge Error (AKE) estimated by the ADCS, and potentially converge to sub-arcsec measurements, whereas 15 to 90 arcsec for AKE are expected on CubeSats and imager pixel size ranges in 10 to 15 arcsec. Results will be available from 2022, thus, instead, we illustrate here possible applications for commissioning and autonomous operations.

“…In collaboration with the Australian Centre for Field Robotics at the University of Sydney, and the SmartSat CRC, whose activities are funded by the Australian government's Cooperative Research Centres (CRC) program, a planned secondary objective using MANTIS is to demonstrate goal-oriented algorithms and software on orbit that will grant a spacecraft mission-autonomy capability to undertake self-inspection autonomously and adaptively in real-time. These goal-driven on-board autonomy activities intend to demonstrate novel scientific innovation in accordance with the latest CubeSat trends for future applications [17]. This could serve applications including fault detection isolation and recovery (FDIR) and guidance navigation and control (GNC).…”

Defence Science and Technology Group (DSTG) is currently preparing for the launch of the Buccaneer Main Mission (BMM) satellite, the successor to the Buccaneer Risk Mitigation Mission (BRMM). BMM hosts a high-frequency (HF) antenna and receiver to contribute to the calibration of the Jindalee Operational Radar Network (JORN). Verification of the successful deployment and stability of the large HF antenna is critical to the success of the mission. A bespoke deployable optics payload has been developed by DSTG to fulfil the dual purpose of direct verification of the deployed state of the HF antenna and capturing images of the Earth through a rotatable, dual-surfaced mirror and a variable-focus liquid lens. The payload advances research at DSTG in several fields of space engineering, including deployable mechanisms, precision actuation devices, radiation-tolerant electronics, advanced metal polishing and optical metrology. This paper discusses the payload design, material selection, trade-offs considered for the deployable optics payload and preliminary test results.
