This book was released on 2018-09-29 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Space Station global positioning systems (GPS) receiver was activated in April 2002. Since that time, numerous software anomalies surfaced that had to be worked around. Some of the software problems required waivers, such as the time function, while others required extensive operator intervention, such as numerous power cycles. Eventually, enough anomalies surfaced that the three pieces of code included in the GPS unit have been re-written and the GPS units were upgraded. The technical aspects of the problems are discussed, as well as the underlying causes that led to the delivery of a product that has had numerous problems. The technical aspects of the problems included physical phenomena that were not well understood, such as the affect that the ionosphere would have on the GPS measurements. The underlying causes were traced to inappropriate use of legacy software, changing requirements, inadequate software processes, unrealistic schedules, incorrect contract type, and unclear ownership responsibilities.

Book Synopsis Inside the International Space Station (ISS) by : World Spaceflight News
Download or read book Inside the International Space Station (ISS) written by World Spaceflight News and published by . This book was released on 2018-03-28 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Learn about the International Space Station (ISS) from the textbooks used by the astronauts! These astronaut and flight controller training manuals, produced by the Mission Operations Directorate (Space Flight Training Division branch) at NASA's Johnson Space Center, represent a major part of the formal flight crew training process. The manuals and workbooks are extremely detailed and comprehensive, and are designed for self-study. A full listing of all acronyms and abbreviations used in the text is included. They provide a superb way to learn about Station systems, hardware, and operational procedures. Special emphasis on crew interaction with the displays, controls, and hardware is included. This training manual covers the ISS guidance, navigation, and control (GNC) system. Contents include: U.S. Guidance, Navigation, and Control Overview * GNC Subsystem Software * Navigation * U.S. Attitude Control Subsystem * Motion Control System (MCS) Operations * GNC Computer System Details * Global Positioning System * ACS Performance Capabilities * GNC OPS Guidance is used to tell the Station which route to follow from point A to point B. For the Station, this is generally executed as a point and fire reboost. The U.S. GNC Subsystem provides some guidance planning support; however, guidance is generally a Russian function. Navigation is composed of the functions state determination, attitude determination, and Pointing and Support (P&S). This definition is different from that used on Shuttle, where navigation and state determination terms are used interchangeably. State determination answers the question, "Where am I?", attitude determination answers the question, "How am I oriented?", and Pointing and Support answers the question, "Where is everything else?" The U.S. GNC Navigation Subsystem consists of software components residing in U.S. GNC Multiplexer/Demultiplexers (MDMs) and a set of GNC Orbital Replacement Units (ORUs). The U.S. GNC Navigation Subsystem maintains the onboard estimate of the position, velocity, attitude, and attitude rate of the ISS after Flight 8A. State determination provides the ISS state vector (position and velocity at a specific time). The Global Positioning System (GPS) enables the Station to determine its position and velocity without ground uplinked data. The GNC flight software maintains precision estimates of position and velocity through propagation algorithms. These propagators accept periodic updates of the state vector data. Data is nominally provided by GPS but may also be provided by RS or ground-based updates. The RS GNC exchanges data with the U.S. GNC MDMs for redundancy and comparison tests. The U.S. GNC Subsystem uses a GPS interferometry technique to determine the attitude of the Station. The GPS provides attitude updates to the U.S. GNC software once every 10 seconds, when at least four GPS satellites are in view. Two Rate Gyro Assemblies (RGAs) provide attitude rate information to propagate the attitude between GPS updates.
