Abstract
A system for estimating aerial vehicle status includes an aerial vehicle, a computing device, and a wireless communication link that communicatively couples the aerial vehicle and the computing device. The aerial vehicle includes a sensor that outputs telemetry data. The computing device includes a processor and a memory. The memory stores instructions that, when executed by the processor, cause the computing device to retrieve the telemetry data from the sensor via the wireless communication link, execute an estimation algorithm based at least in part on the telemetry data, and determine a state of the aerial vehicle based on a result of the estimation algorithm.
Claims19
A system for estimating aerial vehicle status, comprising:
- an aerial vehicle including a sensor that outputs telemetry data;
- a computing device including a processor and a memory;
- and
- a wireless communication link that communicatively couples the aerial vehicle and the computing device,
- wherein the memory stores instructions that, when executed by the processor, cause the computing device to:
- retrieve the telemetry data from the sensor via the wireless communication link,
- detect a failure of the sensor of the aerial vehicle;
- determine whether a telemetry alternative is available, including determining whether a sensor of another aerial vehicle is available to provide data similar to that which otherwise would have been provided by the sensor;
- in response to determining the telemetry alternative is available, configure the telemetry alternative in response to the failure of the sensor;
- execute an estimation algorithm, by an estimation module configured to estimate a status of a parameter and selected from a plurality of estimation modules configured to estimate a state of the aerial vehicle, based at least in part on the telemetry data, and
- determine the state of the aerial vehicle based on a result of the estimation algorithm,
- wherein the plurality of estimation modules comprises a dependency tree, one or more of the plurality of estimation modules dependent on a prerequisite estimation module.
