What is GPS Satellite System Overview and Errors about?
Global Positioning System (GPS) satellites orbit the Earth at an altitude of about 10,900 nautical miles. There are currently 32 operational GPS satellites that make up the GPS constellation. The GPS system uses spread spectrum and pseudo-random noise codes to transmit signals from satellites to receivers. Sources of error in GPS positioning include satellite clock bias, ionospheric delay of signals, tropospheric delay of signals, and receiver clock bias. Accurate GPS requires modeling and accounting for th
