Abstract
A system can include a satellite signal receiver, a computing system, and an optional sensor. The computing system can include a measurement engine, a positioning engine, one or more integrity modules, and an optional combiner. A method can include receiving satellite signals, optionally monitoring the satellite signals, determining a positioning solution, determining an integrity associated with the positioning solution, and optionally operating an external system.
Claims20
A system comprising:
- an antenna configured to receive satellite signals from satellites for global positioning;
- a positioning engine configured to determine a positioning solution of a body by processing the satellite signals and satellite corrections associated with the satellites for global positioning;
- a first integrity module configured to determine one or more parameters associated with a probability distribution associated with the positioning solution of the body, wherein the one or more parameters associated with the probability distribution are used to determine a first protection level of the positioning solution;
- a second integrity module configured to determine a second protection level of the positioning solution independently from the first protection level;
- and
- a combiner to combine the first protection level with the second protection level to determine a protection level of the positioning solution.
