Systems and methods for determining bearing
First Claim
1. A method for determining corrected bearings, the method comprising:
- a step for determining a first uncorrected bearing in accordance with signals received using directional reception;
a step for calculating a correction amount in accordance with the first uncorrected bearing and received positional data; and
a step for applying the correction amount to subsequently determined uncorrected bearings to provide the corrected bearings.

Abstract
A system determines bearing for situational awareness. The system may include a receiver, a processor, and a memory comprising an engine for performing a method. The method includes receiving signals using directional reception; receiving positional data; calculating a correction amount; and applying the correction amount to subsequent uncorrected bearings to provide corrected bearings. Positional data may be received in any conventional format including data link, ADS-B, and MODE S. Positional data may be determined in the target using a global positioning system. The system may provide a signal to display the corrected bearing and/or provide traffic alerting and collision avoidance advisories.

3. A method for situational awareness performed by a system aboard a host vehicle, the method comprising in sequence:
-
a step for determining a first uncorrected bearing in accordance with a first signal and a direction, the first signal associated with a first target relative to the host vehicle, the first signal in further accordance with directional reception from the direction;
a step for determining a correct-bearing in accordance with received positional data, the data being in accordance with the direction;
a step for determining a correction amount in accordance with the first uncorrected bearing and the correct bearing;
a step for determining a second uncorrected bearing in accordance with a second signal, the second signal associated with a second target relative to the host vehicle, the second signal in further accordance with directional reception from the direction; and
a step for determining a corrected bearing in accordance with the second uncorrected bearing, the correction amount, and the direction. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 27, 28)
