& Nbsp; December 20 & nbsp; L3Harris Technologies completed the development of the project and & nbsp; has already started directly to create a sample of the new satellite. The satellite is designed for the Hypersonic and Ballistic Tracking Space Sensor (HBTSS) & nbsp; & mdash; this is the name of the new satellite constellation. New satellite constellation should 'fill the gap' in the & nbsp; American missile defense system. HBTSS & nbsp; & mdash; one of & nbsp; several proposed systems in & nbsp; the widespread space architecture of the new generation of the Department of Defense in & nbsp; low Earth orbit. Both companies should deliver their satellites in & nbsp; 2023 & nbsp; year. < p>The Missile Defense Agency and the Space Development Agency have approved a number of projects for new satellites. '' Therefore, to detect and & nbsp; track ballistic and & nbsp; hypersonic missiles, satellites of the HBTSS program, equipped with infrared sensors and & nbsp; data processing systems in & nbsp; orbit, will be tested in two years. It was reported there that it is planned to launch the first vehicles into & nbsp; orbit in & nbsp; 2022 fiscal year (will start in & nbsp; October 2021 & nbsp; year). Source: https: //spacenews. Details about & nbsp; promising spacecraft have not yet been & nbsp; disclosed. The main difference between the new satellites & nbsp; & mdash; they will be in low-earth orbit. The lower the orbit, the more 'effort' must be applied to the apparatus to maintain its trajectory. The company provides advanced defense and & nbsp; commercial technologies in space, in & nbsp; air, & nbsp; land, & nbsp; sea and & nbsp; in & nbsp; cyberspace. L3Harris has an annual income of about $ 18 & nbsp; and & nbsp; has 47 & nbsp; 000 & nbsp; employees and & nbsp; its & nbsp; clients are located in more than & nbsp; 100 & nbsp; countries. The purpose of the program & nbsp; & mdash; Demonstrate the ability to detect and & nbsp; track traditional and emerging missile threats with & nbsp; infrared sensors and & nbsp; advanced processing capabilities. The device has passed a critical design check, the company said. In & nbsp; January, the Missile Defense Agency awarded & nbsp; Northrop Grumman a contract for & nbsp; $ 155 million and & nbsp; L3Harris for & nbsp; $ 121 million to & nbsp; develop prototypes for demonstration in & nbsp; orbit. In & nbsp; December 2020, the Space Development Agency selected L3Harris to build and & nbsp; launch four spacecraft that are capable of detecting and & nbsp; tracking ballistic and & nbsp; hypersonic missiles. Previously, Northrop Grumman did the same. com/l3harris-missile-tracking-satellites-pass-critical-design-reviews/ Истoчник aif.ru But, like & nbsp; always, the timing of the program has shifted. The & nbsp; Pentagon began the development and & nbsp; creation of space satellites for monitoring hypersonic weapons. For reference: L3Harris Technologies & nbsp; & mdash; company & nbsp; & mdash; a global innovator in the & nbsp; field of aerospace and & nbsp; defense technologies. Existing satellites usually cannot detect and & nbsp; track a hypersonic target. Agreements for & nbsp; launching satellites into & nbsp; low-earth orbit will be signed later. The current spacecraft designed to track ballistic missile launches are in a & nbsp; higher orbit. Last year, the Space Research Agency, part of the US Space Force, released the requirements for & nbsp; reconnaissance satellites that will be responsible for & nbsp; detection and & nbsp; tracking of hypersonic weapons. The list includes a missile tracking satellite developed by L3Harris for the US Missile Defense Agency. The Pentagon believes that they are necessary in & nbsp; in connection with the & nbsp; accelerated creation in & nbsp; the world, in & nbsp; including in & nbsp; Russia and & nbsp; China, hypersonic weapons, which are much more dangerous and & nbsp; less noticeable than conventional ballistic missiles. L3Harris President said recent events, including the demonstration in China of a hypersonic glider, “ heightens the need to counter hypersound and & nbsp; modern maneuvering threats.
