UNMANNED AERIAL VEHICLE RECOVERY SYSTEM
First Claim
1. An unmanned aerial vehicle comprising:
- a primary operation system in communication with a primary state estimator, the primary operation system being configured to operate the unmanned aerial vehicle based in part on the primary state estimator; and
a flight failure recovery system in communication with the primary operation system and a recovery state estimator, the flight failure recovery system being configured to generate a deploy signal based at least in part on one or more signals from the recovery state estimator.

Abstract
An unmanned aerial vehicle includes a closely integrated emergency recovery and operation systems for an unmanned aerial vehicle with built-in levels of redundancy and independence to maximize the likelihood of a controlled velocity landing. The unmanned aerial vehicle may include multiple processors and multiple state estimating modules such as inertial measurement units to independently determine the operational and error status of the unmanned aerial vehicle. Base on predictive or projected computations, the emergency recovery system may determine a suitable time for a recovery action, such as parachute deployment, and execute the recovery action.
