Abstract
Techniques for incorporating blended Global Navigation Satellite System (GNSS) and Inertial Navigation System (INS) integrity monitoring information as a connected network database are described. Information relating to the integrity of known instances of GNSS disturbances can be stored and accessed by users. The information can include data regarding the integrity of GNSS/INS position solutions generated from vehicles a priori, such as the location, time, and any known causes of the GNSS disturbance. The database can be located on a vehicle and/or on a remote server that can be shared to other users with access to the database. In some embodiments, access can be restricted to certain users if the data stored is confidential.
Claims20
A system, comprising:
- a plurality of vehicles;
- a navigation system onboard at least one vehicle of the plurality of vehicles, wherein the navigation system comprises a Global Navigation Satellite System (GNSS) receiver and an Inertial Navigation System (INS);
- and
- at least one processor coupled to the navigation system, wherein the at least one processor is configured to:
- receive navigation data measurements or navigation integrity data measurements from the navigation system,
- analyze the received measurements,
- identify one or more navigation parameters of at least one GNSS disturbance based on the analysis of the received measurements, generate data based on the one or more navigation parameters, store the generated data, and
- disseminate the generated data between one or more vehicles of the plurality of vehicles, wherein the generated data comprises at least one of:
- GNSS satellite exclusion occurrences determined based on a combination of GNSS data from the GNSS receiver and inertial data from the INS, and differences in navigation subsystem measurements.
A non-transitory computer-readable medium having computer-executable instructions stored thereon which, when executed by one or more processors, cause the one or more processors to:
- receive navigation data measurements or navigation integrity data measurements from at least one navigation system, wherein the at least one navigation system comprises a Global Navigation Satellite System (GNSS) receiver and an Inertial Navigation System (INS) located on one of a plurality of vehicles;
- analyze the received measurements;
- identify one or more navigation parameters of at least one GNSS disturbance based on the analysis of the received measurements;
- generate data based on the one or more navigation parameters;
- store the generated data;
- and
- disseminate the generated data between one or more vehicles of the plurality of vehicles, wherein the generated data comprises at least one of:
- GNSS satellite exclusion occurrences determined based on a combination of GNSS data from the GNSS receiver and inertial data from the INS, and differences in navigation subsystem measurements.
A method, comprising:
- receiving a request for information about known GNSS disturbances;
- accessing a database, wherein the database comprises generated data, the generated data generated by:
- receiving navigation data measurements or navigation integrity data measurements from a navigation system, wherein the navigation system comprises a Global Navigation Satellite System (GNSS) receiver and an Inertial Navigation System (INS) located on one of a plurality of vehicles,
- analyzing the received measurements,
- identifying one or more navigation parameters of at least one GNSS disturbance based on the analysis of the received measurements, wherein the generated data is based on the one or more navigation parameters, wherein the generated data is stored in the database, and
- providing the generated data in response to the request, wherein the generated data comprises at least one of:
- GNSS satellite exclusion occurrences determined based on a combination of GNSS data from the GNSS receiver and inertial data from the INS, and differences in navigation subsystem measurements.
