For more than 50 years CPI has been developing high-precision satellite tracking and control systems. As the world’s leading manufacturer of ground-based products and services, CPI's systems are designed using cutting-edge technology by the company's experienced engineering team. CPI provides a variety of Antenna Control Systems and tracking receivers to fit your application. Antenna Control Systems can be used in a wide range of applications, including telecommunications, radio and television broadcasting, radar, and satellite communications. The specific components of an Antenna Control System can vary depending on the type of antenna and application, but they generally include motors, actuators, interface sensors, software, and tracking receiver equipment. An Antenna Control System (ACS) is a system that is used to control the position and configuration of an earth station antenna in order to optimize its performance for a specific application. A Tracking Receiver Unit (TRU) is portion of the Antenna Control System designed to receive signals from a satellite and provide tracking inputs to the Antenna Control System. These precision products and systems provide cost-effective solutions to keep you connected and in control of your antennas. CPI control systems can be used with almost any antenna and support a wide range of applications, including new systems, upgrades to existing equipment, or retrofits of legacy systems.

An ideal feedback control system cancels out all errors, effectively mitigating the effects of any forces that may arise during operation and producing a response in the system that perfectly matches the user's wishes. The space applications this discipline encompass includes satellite attitude and orbit control, antennas or optical terminal fine pointing, and more generally guidance, navigation and control for space vehicles that have to accomplish specialised functions such as formation flying and orbital rendezvous, landing on asteroids and planetary bodies as well as re-entry through Earths atmosphere. Control engineering focuses on the modelling of dynamic systems and the design of closed-loop controllers that cause these systems to behave in the manner desired. In a closed-loop control system, a set of sensors monitors the output (for example, the satellite pointing direction, or the space vehicle relative position) and feeds the data to a computer which continuously adjusts the control input (through actuators) as necessary to keep the control error to a minimum (that is, to maintain the desired pointing orientation or relative position). Attitude and Orbit Control Systems (AOCS) are required for all space missions. The general scope of a satellites trajectory is set by the launcher that hauls it skyward – selected by orbital dynamics experts long in advance of the satellite being built – after which smaller thrusters manoeuvre it into its operational orbit. After that the onboard closed-loop control is in charge of controlling the spacecrafts pointing direction – known as its attitude – as it proceeds along its orbital path. The problem is that satellites have their attitude perturbed in various ways, whether by airdrag from the outermost layers of the atmosphere or Earths gravitational influence or solar radiation pressure exerted on large appendages, or interaction between Earth's magnetic field and satellite magnetic dipoles.

It provides command and control of satellite operations, scheduling, data reception, and initial (level 0) processing of data processing capabilities. The Science Operations focuses on building the following capabilities: generating high-level (Level 1–4) scientific data products for EOS tasks, archiving, and distributing data products from EOS and other satellite missions, as well as aircraft and on-site measurement activities. These centers work closely together to follow the same standards in data product organization, data product description, metadata coding, and multidata product retrieval. Together they implement reliable and powerful data services, including assistance in selecting and acquiring data, accessing data processing and visualization tools, and technical support. ... Standard ground stations can amortize their costs over a large number of satellites and missions, and provide re-use of hardware and software resources. There are NASA standard ground stations, the U.S. Air Force Satellite Control Network (AFSCN), and the Deep Space Network (DSN) for interplanetary missions. From that time, GPS has been used widely for numerous civilian applications on the land, sea and in air. The GPS system is divided into three sub-systems like space sub-system (the satellites), control sub-system (the ground stations) and user sub-system (GPS receivers). Figure 5.

The students of the Academy developed on the basis of serial satellite manufactured by NPO of Applied Mechanics the educational non-oriented small satellite MOZHAETS [16]. The satellite is intended for student training in methods of satellite guidance and control, analysis of telemetry information by regular means of educational command — measuring complex.

Satellite control systems: Technologies supporting satellites | NEC

Satellites carry out missions far from Earth, in the vastness of space. Monitoring and controlling their health from the ground is essential for the completion of these missions. For example, the Hayabusa satellite collected samples from the asteroid Itokawa and backed to Earth after a seven-year journey. How do we know the status and send commands to satellites that are so far away? The task of monitoring and controlling the health of satellites operating in space is carried out by satellite control systems at ground-based control centers. Each satellite has a dedicated satellite control system in place to manage its operations, whether for communication, navigation, Earth observation, or other purposes. The satellite control system monitors satellites through ground stations on Earth. Using antennas at these ground stations, it communicates with the satellites via digital signals to check their position and health status. As needed, it adjusts the satellite's orbit or attitude and gives instructions for missions, such as taking photographs. This ensures that the satellites are correctly positioned and can fulfill their intended purposes. All communications are encrypted to ensure security. NEC Satellite Operation Center Operation of ASNARO-2 high-resolution small radar satellite developed by NEC · Satellite control operations consist of mission planning, satellite monitoring and control, and orbital mechanics calculations.
