Functions¶

normalizeLongitude()¶

function normalizeLongitude(lon): number;

Defined in: utils/geo.ts:11

Wrap a longitude (or longitude delta) into [-180, 180]. BlueSky only normalizes longitude at aircraft creation (cre in bluesky/traffic/traffic.py); update_pos integrates it unbounded, so an aircraft that crosses the antimeridian keeps reporting lon beyond ±180.

Parameters¶

lon¶

number

Returns¶

number

computeBearing()¶

function computeBearing(
   lat1, 
   lon1, 
   lat2, 
   lon2
): number;

Defined in: utils/geo.ts:20

Aviation bearing from (lat1, lon1) to (lat2, lon2). 0° = North, clockwise. Returns a value in [0, 360).

Parameters¶

lat1¶

number

lon1¶

number

lat2¶

number

lon2¶

number

Returns¶

number

roundedBearing()¶

function roundedBearing(
   lat1, 
   lon1, 
   lat2, 
   lon2
): number;

Defined in: utils/geo.ts:44

computeBearing rounded to a whole degree, normalized so 359.6° reads as 0° rather than 360°. This is the value shown in heading readouts and written into CRE commands.

Parameters¶

lat1¶

number

lon1¶

number

lat2¶

number

lon2¶

number

Returns¶

number
