GPS + Flat Earth publish.obsidian.md/shanesql… The transformation process from a satellite's local frame to user-friendly geographic coordinates involves several steps, each serving a specific purpose in ensuring accurate positioning and orientation. Once again, there is a chain of custody issue involving a break between a) attitude data that would need to be independently verifiable and b) cartesian data that is being delivered for consumption. Pitch, Roll, and Yaw (Attitude Data) Note: It begins here. This data is proprietary, not open-source, and not independently verifiable. We need this to validate the globe claim. Does it exist? LVLH Frame Note: This local frame describes the satellite's orientation relative to its orbit but does not retain the rotational mechanics from step 1. This data is not always impossible to get but does not contain rotational attitude data that we need for a globe. ECI Frame Note: This is a Cartesian XYZ reference frame that is inertial with respect to the stars and is used for precise orbital mechanics and adjusting the satellite's position. This is the “driver’s seat.” ECEF Frame Note: This is a Cartesian XYZ reference frame that is inertial to the earth and is used for ground tracking. It is essentially a pac-man earth model. WGS84 Coordinates Note: This is the global reference system that end users see on their devices, providing latitude, longitude, and altitude. This sequence ensures that the satellite's data is accurately transformed and presented in a format that is both precise for technical calculations and user-friendly for practical applications. It does not prove the globe. Reference: Blewitt, G. (2015). GPS, Reference Systems. In Encyclopedia of Geodesy. Nevada Bureau of Mines and Geology. Retrieved from nbmg.unr.edu/staff/pdfs/Blew… he Earth-Centered Inertial (ECI) system holds great significance in satellite navigation, including GPS systems. It serves as a non-rotating coordinate system, fixed with respect to the Earth without any rotation. The ECI system enables accurate positioning and velocity data, which are crucial for precise navigation. Within the ECI coordinate system, the Sagnac correction comes into play. It accounts for the Sagnac effect, which is observed in rotating systems where light traveling in opposing directions around a closed loop experiences different speeds. This correction compensates for the Earth's rotation and is indispensable for accurately synchronizing clocks and measuring the speed of light. In contrast, the Earth-Centered Earth-Fixed (ECEF) system, which remains fixed with respect to the rotating Earth, does not require the Sagnac correction. This is because the system inherently takes into account the Earth's rotation. The speed of light remains unaffected by the Earth's rotation when navigating north or south. However, the east or west direction does impact the speed of light due to the Earth's rotational motion. Light moving in the direction of the Earth's rotation appears slightly faster, while light moving counter to the Earth's rotation seems marginally slower. This difference is attributed to the Sagnac effect, which considers the Earth's rotation within the ECI coordinate system The term c+v signifies the velocity of light in a moving or rotating frame of reference. Here, c represents the speed of light and v stands for the velocity of the observer with respect to the light source. This term demonstrates the apparent speed of light as perceived by an observer moving relative to the source of light. The collection of PDFs broadly explores the concepts of relativity, the Sagnac effect, and their applications in systems like GPS. Key points include: C+V and Speed of Light: Some documents discuss the notion of light speed in moving frames, often referencing the C+V formula, where C is the speed of light in a vacuum and V is the velocity of the frame. This concept is explored in the context of relativistic effects on light propagation. ECF and ECI: Earth-Centered Fixed (ECF) and Earth-Centered Inertial (ECI) coordinate systems are mentioned. ECF is fixed relative to the Earth's surface, while ECI is fixed relative to the stars. The distinction between these frames is crucial for understanding GPS operations and relativistic corrections. Sagnac Effect: Several documents address the Sagnac effect, which occurs due to rotation and affects the phase of light traveling in opposite directions in a rotating frame. It's particularly relevant for systems like fiber optic gyroscopes and GPS. Coordinate Systems and Sagnac Corrections: The application of Sagnac corrections in different coordinate systems is discussed. For GPS, which operates using both ECF and ECI frames, Sagnac corrections are vital to ensure accuracy. However, in an ECI frame, these corrections may not be necessary as it is non-rotating relative to distant stars.
