Point a Loon

We highly believe that project Loon implementation can be greatly improved by using directional LTE atennas so we developed a Loon tracker and antenna tracker, with this you can get a DIY antenna tracker following the nearest balloon to your location, further improvemnts comming! Our software is open-source, so you can host your own loon tracker; however, we have deployed a public API to ease this system implementation.

API Usage

The API we provide is hosted at Google Firebase, remember you need to create an API token first.

API Token generator

Get a token to use our hosted API.

Tokens without activity in a long time period will be deleted, calling /point periodically will prevent that.

Point Antenna

/point GET Request


Parameters required:

Response: JSON with desired azimuth and altitude data for atenna in degrees, distance to the nearest balloon, and object Loon with balloon data (callsign,altitude,speed,postion,track,etc).

{"ant_alt":-13.044651036040841, "ant_azm":314.3787496140375, "distance":2966056.5460053235, "loon":{"alt":15788.639494763536, "lat":-11.8075,"lng":-76.2704, "name":"HBAL941","seen":1500638350, "speed":15,"track":121} }

This also will update your token last activity.
For initial postioning you need to have a minimal connection to the network, the request size is as little as 500 bytes of data.

Get live Loon balloons status

/loons GET Request


Parameters required:

Response: JSON with all objects Loon detected, each object include callsign,altitude,speed,postion,track,etc from balloon.
This also will update your token last activity.

{"HBAL020":{"alt":16093.439485009936,"lat":-6.3734,"lng":-78.456,"name":"HBAL020","seen":1500760514,"speed":7,"track":203}, "HBAL044":{"alt":17708.87943331586,"lat":-3.6557,"lng":-61.919,"name":"HBAL044","seen":1500760515,"speed":16,"track":119}, "HBAL051":{"alt":15819.119493788176,"lat":-0.478,"lng":37.6499,"name":"HBAL051","seen":1500760511,"speed":6,"track":270}... }

This also will update your token last activity.
