The attitude determination and control sub-system is a critical unit for the mission performance quality of a satellite when it operates in orbit. This sub-system ensures accuracy when pointing satellite and maintains stability during attitude control. This article presents the development process of a specialised kit named ADCS kit with associated exercises in attitude determination and control in the Vietnam National Space Center based on the in-depth research results in this field. Using a specialised kit while training and practising attitude determination and control for the satellite is also required, especially when the satellite operates in a spatial environment with near-zero gravity and non-friction. The kit is assembled with basic hardware of the attitude determination and control sub-system, such as an inertial measurement unit (IMU) and several reaction wheels, which can achieve near-zero gravity and non-friction state. Three wheel configurations, which are 3-axis standard, pyramid and tetrahedron, are proposed, allowing the execution of several different attitude control schemes for the training activities. The ADCS kit is a product developed under the grant of the Technology Development Program of the Vietnam Academy of Science and Technology.Xác định và điều khiển tư thế là phân hệ rất quan trọng đối với chất lượng thực hiện nhiệm vụ của vệ tinh khi hoạt động trên quỹ đạo.
