AltAzRange - Calculate altitude, azimuth, distance from gps cords

Simple tool to calculate altitude (elevation), azimuth and range between observer and object or pair of coordinates.

Useful for eg. finding where to aim your antenna - no matter if it's drone, satellite, high altitude balloon.

Instalation

$ pip install altazrange

Basic Usage

from AltAzRange import AltAzimuthRange
satellite = AltAzimuthRange()
satellite.observer(51.77021, 18.061959, 115)
satellite.target(51.681562, 17.778988, 43152)

satellite.calculate()
{'azimuth': 245.49, 'elevation': 86.86, 'distance': 430555.14}

Usage for multiple objects with single observer location

If you want to use same observer for multiple objects its recommended to use default_observer

from AltAzRange import AltAzimuthRange
AltAzimuthRange.default_observer(51.773931, 18.061959, 50)
satellite_1 = AltAzimuthRange()
high_alt_balloon = AltAzimuthRange()
satellite_1.target(51.681562, 17.778988, 43152)
high_alt_balloon.target(52.30, 21.37, 190000)

satellite_1.calculate()
{'azimuth': 245.49, 'elevation': 86.86, 'distance': 430555.14}

high_alt_balloon.calculate()
{'azimuth': 74.1, 'elevation': 37.55, 'distance': 304391.38}

Default observer can be overwritten using observer method.
