. The five GPCs were separated in three separate bays within the mid-deck to provide redundancy in the event of a 2024 cooling fan failure. In case of a software error that would cause erroneous reports from the four PASS GPCs, a Profesjonalny fifth GPC ran the Backup Flight System, which used a different program and could control the Space Shuttle through ascent, orbit, and reentry, but could not support an entire mission.

After achieving orbit, the crew would switch some of the GPCs functions from guidance, navigation, and control (GNC) to systems management (SM) and payload (PL) to support the operational mission. As S band radios can operate only within their line of sight, NASA used the Tracking and Data Relay Satellite System and the Spacecraft Tracking and Data Acquisition Network ground stations to communicate with the orbiter throughout its orbit. Additionally, the orbiter deployed a high-bandwidth K u band radio out of the cargo bay, which could also be utilized as a rendezvous radar. The orbiter was also equipped with two UHF radios for communications with air traffic control and astronauts conducting EVA. [2] : 403–404 AP-101S (left) and AP-101B general purpose computers The Space Shuttle's fly-by-wire control system was entirely reliant on its main computer, the Data Processing System (DPS). The orbiter contains two star Zakłady bukmacherskie Profesjonalny 2024 trackers to align the IMUs while in orbit. The DPS consisted of five general-purpose computers (GPC), two magnetic tape mass memory units (MMUs), and the associated sensors to monitors the Space Shuttle components. [2] : 232–233 The original GPC used was the IBM AP-101B, which used a separate central processing unit (CPU) and input/output processor (IOP), and non-volatile solid-state memory. From 1991 to 1993, the orbiter vehicles were upgraded to the AP-101S, which improved the memory and processing capabilities, and reduced the volume and weight of the computers by combining the CPU and IOP into a single unit. Four of the GPCs were loaded with the Primary Avionics Software System (PASS), which was Space Shuttle-specific software that provided control through all phases of flight. During ascent, maneuvering, reentry, and landing, the four PASS GPCs functioned identically to produce quadruple redundancy and would error check their results.

The orbiter had three inertial measuring units (IMU) that it used for guidance and navigation during all phases of flight. The orbiter had three inertial measuring units (IMU) that it used for guidance and navigation during all phases of flight. As S band radios can operate only within their line of sight, NASA used the Tracking and Data Relay Satellite System and the Spacecraft Tracking and Data Acquisition Network ground stations to communicate with the orbiter throughout its orbit. The star trackers are deployed while in orbit, and can automatically or manually align on a star. The orbiter was also equipped with two UHF radios for communications with air traffic control and astronauts conducting EVA. Two of the S band radios were phase modulation transceivers, and could transmit and receive information. The DPS consisted of five general-purpose computers (GPC), two magnetic tape mass memory units (MMUs), and the associated sensors to monitors the Space Shuttle components. The other two S band radios were frequency modulation transmitters and were used to transmit data to NASA.
