Étant donné que les technologies de l’information sont de plus en plus utilisées, les fournisseurs doivent assurer la maximisation de la bande passante de leurs installations en tout temps. Pour les réflecteurs embarqués sur les satellites, cela signifie qu’un minimum de distorsion thermique est souhaitable pour obtenir un maximum de performance. Ces distorsions thermiques apparaissent […]

In the near future, a large quantity of satellites will be used to provide Internet and communication services everywhere on Earth. Most of these satellites will be moving at very high speeds on orbits close to Earth which implies the satellites will be moving relative to a user on the ground. As a result, the […]

Our space-based radio-frequency communication is suffering from the use of simple phase shifters. Its bandwidth capability is limited, ultimately reducing the satellite’s capacity and the system’s service availability. Most electronic beamforming implementations are bulky, frequency dependent and they consume a significant amount of power. To replace those electronic components, structures which guide light on microchips […]

Due to the fast mobility of LEO satellites, ground users need to switch between LEO satellites frequently to keep the connection with the satellite network. The process of switching between satellites is called the handover process. Every handover process is associated with signalling overhead, processing delays, and data packet losses. The optimization of the handover […]

The objective of this research is to propose and implement a set of new methodologies to create a 3D hazard map that includes models of structures and obstacles in the airport area. The project uses multiple oblique and nadir views high resolution aerial imageries (pictometery images) to reconstruct such models. Various views of an obstacle […]

The objective of this project is to participate in the development of automated methods for the extraction of cartographic features from satellite images with high spatial resolutions. Emphasis will be placed on man-made features of interest, including roads, settlement extent and large infrastructures, etc. This will involve review and performance assessment of existing methods, data […]

The objective of this project is the research of multi-sensor Appearance Based SLAM (ASLAM) system for day/night operations in indoor and outdoor environments. These algorithms would perform place recognition based on multiple sensor data (imagery, laser, and radar) gathered from a UGV (Unmanned Ground Vehicle) as it travels through the environment. When the vehicle returns […]

In an alien or possibly hostile environment, the situation awareness of a remote robot operator will be limited. Map information may not be known beforehand. The site may also be in a dynamic state where changes occur in the surrounding in any moment. The main objective of this project is to develop novel technologies to […]

Space structures must be designed to resist the harsh space environment, which include but it is not limited to atomic oxygen, ionizing radiation, charged particle plasma, man-made debris and micrometeoroids. Thus, the spacecraft must be designed to have high stiffness, low thermal expansion and high dimensional stability. Composite materials can be designed to fulfill those […]

Autonomous mobile robots which are designed to operate in unknown environments, such as Mars or the Moon surface must be robust to unpredictable challenges and capable of making correct decisions to survive. One of the important tasks of rovers is to locate themselves in an environment where no navigation aids such as GPS is available. […]

Few things in space flight are routine. Before each time MDA operates the International Space Station’s famous Canadarm2, thousands of simulations must be performed to ensure the success and safety of the operation. This research intends to streamline the process of operations planning for Canadarm2 by using machine learning to predict key outputs from these […]

Currently, when man-made objects in orbit around the Earth need to be disassembled or repaired, a humancontrolled robotic manipulator is used. The object in question is often not designed to be modified in this manner, and only 1 in 4 human operators at MDA (the partner organization) are able to successfully complete these notoriously challenging […]
