View source for SDR Satcom Applications

== Introduction ==

Here you can find details of the snaps in the SDR Satcom app store.

Note that there is also a [https://sdrsatcom.snapcraft.io/ web interface to the store] which allows you to view additional details, such as the licence and time of last update.

For details of how to install snaps and contributing, see [[SDR Satcom App Store]].

== Categories ==

There are currently two categories of application:

* Community contributed apps
* Reference apps provided by Lime Micro

=== Community ===

==== Gpredict ====

[[File:Gpredict 1 768w.jpg]]

[https://github.com/csete/gpredict Gpredict] is a real time satellite tracking and orbit prediction program for the Linux desktop. It uses the SGP4/SDP4 propagation algorithms together with NORAD two-line element sets (TLE).

==== SatHelperApp ====

[[File:SatHelperApp 1 768w.jpg]]

The OpenSatelliteProject (OSP) [https://github.com/opensatelliteproject/SatHelperApp Satellite Helper Application] is currently an LRIT/HRIT demodulator / decoder program based on libSatHelper and xritdemod.

==== SDRangel ====

[[File:LimeSDR-Mini SDRangel Demo 768w.jpg]]

[https://github.com/f4exb/sdrangel SDRangel] is a Qt5 / OpenGL 3.0+ SDR and signal analyzer frontend. It has support for various modes, including DVB, and transmit operation.

==== WeatherDump ====

[[File:Weatherdump_alpha3_demo.png]]

[https://github.com/luigifreitas/weatherdump WeatherDump] is multi-platform software for record, demodulate, decode and processing of data from weather satellites.

=== Reference ===

A small number of reference applications are provided by Lime Microsystems.

The snapcraft build/packaging meta-data for these can be found on [https://github.com/myriadrf/snapcraft-sandbox GitHub].

==== Lime Suite  ====

Lime Suite driver and utilities only.

This minimal snap is useful for validating operation of LimeSDR hardware and performing firmware/gateware upgrades.

==== LimeSDR + GRC ====

GNU Radio, GNU Radio Companion (GRC) and gr-limesdr source/sink blocks.

This snap provides a base GNU Radio system, along with the GRC visual flowgraph editor, and blocks for LimeSDR hardware.

==== LimeSDR + Gqrx ====

Gqrx is an open source software-defined radio receiver (SDR) powered by GNU Radio and the Qt graphical toolkit.

''Note that at the present time a device type of "other" should be selected and the device string "driver=lime;soapy=0" used.

==== LimeSDR + Pothos ====

The Pothos project is a complete data-flow framework for creating topologies of interconnected processing blocks.

This snap provides a Pothos environment with Pothos GUI, SDR blocks and LimeSDR hardware support via SoapySDR.
