Abstract
The concepts, systems and methods described herein are directed towards real time carrier phase monitoring and platform attitude solutions on a moving platform. In an embodiment, highly accurate platform attitude and monitored carrier phases can be determined in a single step and use data screening, error bounds inflation and statistical tests to ensure both inputs and outputs of an attitude solution are self-consistent. The method includes determining a carrier phase error level for each of the satellite-receiver tracks, identifying the satellite-receiver tracks having the carrier phase error level greater than or equal to a carrier phase error threshold, generating an attitude correction using the received data from the one or more satellite-receiver tracks having the carrier phase error level less than the carrier phase error threshold and determining a convergence state of the attitude correction. The carrier phase monitoring may be activated or dis-activated based on the convergence level.
