This fork of [rs1279's RS ](https://github.com/rs1729/RS ) codebase
provides a set of utilities ('auto_rx') to allow automatic reception
and uploading of
2020-12-17 23:39:06 +00:00
[Radiosonde ](https://en.wikipedia.org/wiki/Radiosonde ) telemetry to
2019-02-11 08:49:56 +00:00
multiple services, including:
2021-04-23 11:06:59 +00:00
* The [SondeHub Radiosonde Tracker ](https://tracker.sondehub.org ) - a tracking website specifically designed for tracking radiosondes!
2019-02-11 08:49:56 +00:00
2020-12-17 23:39:06 +00:00
* APRS-IS (for display on sites such as [radiosondy.info ](https://radiosondy.info ) and [aprs.fi ](https://aprs.fi )
2017-02-06 17:08:18 +00:00
2020-12-17 23:39:06 +00:00
* [ChaseMapper ](https://github.com/projecthorus/chasemapper ) for mobile
2019-02-11 08:49:56 +00:00
radiosonde chasing.
2020-12-18 00:02:53 +00:00
There is also a web interface available on http://localhost:5000 ,
2019-02-11 08:49:56 +00:00
allowing display of station status and basic tracking of the sonde
position.

2017-12-17 07:59:32 +00:00
Currently we support the following radiosonde types:

* Meteomodem M10 & M20
2019-03-24 07:07:42 +00:00
* Intermet iMet-4 (and 'narrowband' iMet-1 sondes)
2021-01-25 04:13:32 +00:00
* Intermet iMet-54
2020-12-18 00:02:53 +00:00
* Lockheed Martin LMS6 (400 MHz and 1680 MHz variants, including the new 'LMS-X' unreleased type)
2019-12-15 04:25:10 +00:00
* Meisei iMS-100
2021-03-27 04:53:26 +00:00

2017-12-22 01:02:16 +00:00
2019-02-11 08:49:56 +00:00
Support for other radiosondes may be added as required (please send us
sondes to test with!)

This software performs the following steps:
2017-02-06 17:08:18 +00:00
2019-02-11 08:49:56 +00:00
1. Use rtl_power to scan across a user-defined frequency range, and
detect peaks in the spectrum.
2. For each detected peak frequency, run the rs_detect utility, which
determines if a radiosonde signal is present, and what type it is.
3. If a radiosonde signal is found, start demodulating it, and upload
data to various internet services.
4. If no peaks are found, or if no packets are heard from the
radiosonde in a given amount of time (2 minutes by default), go back
to step 1.

2019-02-11 08:49:56 +00:00
The latest version can make use of multiple RTLSDRs to allow for
tracking of many radiosondes simultaneously. The number of
simultaneous radiosondes you can track is limited only by the number
of RTLSDRs you have setup!
