AIRCRAFT NAVIGATION USING EXPONENTIAL MAP
First Claim
1. A computer-implemented method of determining navigation information for an aircraft, comprising:
- accessing, by one or more processors, a satellite-based positioning signal received at a receiver on an aircraft, the satellite-based positioning signal comprising data indicative of a distance between a satellite and the receiver;
identifying, by the one or more processors, from the satellite-based positioning signal a first vector associated with the distance and direction between the satellite and the receiver;
identifying, by the one or more processors, from the satellite-based positioning signal a second vector associated with a distance and direction between a reference point and the satellite;
generating, by the one or more processors, a kinematic model for determining a geometric position of the aircraft using the first vector and the second vector, the kinematic model based at least in part on a robotic arm; and
determining, by the one or more processors, navigation information for the aircraft based at least in part on the kinematic model.

Abstract
Systems and methods for determining navigation information for an aircraft are provided. In one embodiment, a method can include accessing a satellite-based positioning signal received at a receiver on an aircraft. The satellite-based positioning signal can be indicative of a distance between a satellite and the receiver. The method can include identifying from the satellite-based positioning signal a first vector associated with a distance between the satellite and the receiver and identifying a second vector from the satellite-based positioning signal associated with a distance between a reference point and the satellite. The method can include generating a kinematic model for determining a geometric position of the aircraft based at least in part on a robotic arm using the first vector and the second vector and determining navigation information for the aircraft based at least in part on the kinematic model.
