Ham radio satellite and moon azimuth and altitude web service

I’m working on a project to implement a self contained ham radio rotator. It basically will take a command from a mobile device and position itself to point to the satellite selected and follow it while its visible. This also applies for the moon. The objective is to have a self operated wireless rotator control based on object position.

The core of the processor and WiFi will be the ESP8266 or ESP32, not sure yet.

I am working on the mechanical design and currently have a working prototype. I will post about this project later.

As part of the tools required, I needed a simple web service that returned the satellite azimuth and elevation, a service that could be called from a WiFi controller that has not a lot of resources. Just get the azimuth and elevation of the satellite based on home coordinates and desired object.

I have the service working, if anybody wants to try it, let me know as it needs an access token. Is still work in progress.

The format of the service is:

http://server_ip/get_sat_data.php/?token=xxxxxxxx&name=ukube&lat-50.1345&lon=-112.4321&ele=560

token: access token
name: satellite or moon
lat: observer’s latitude
lon: observer’s longitude
ele: observer’s elevation in meters

the service returns a JSON string:

{‘azi’: 201:07:35.3, ‘alt’: 26:08:25.5, ‘name’: ‘ukube’}

azi: azimuth of the satellite in degrees
alt: altitude of the satellite in degrees
name: name of the satellite

To get a list of the objects support just issue :

http://server_ip/get_sat_data.php/?token=xxxxxxxx&name=list

Contact me if interested in testing the service, adding satellites or just giving me feedback.
