SDR Satcom Applications

1 Introduction

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

Note that there is also a 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.

WeatherDump is multi-platform software for record, demodulate, decode and processing of data from weather satellites.

2.1.4.1 Supported Datalink Protocols
Protocol Complete Name Satellites Band Support Leve
LRPT Low Rate Picture Transfer Meteor-MN2 VHF Alpha
HRD High Rate Data NOAA-20 & Suomi X-Band Beta
APT Automatic Picture Transfer NOAA-15, NOAA-18 & NOAA-19 VHF Planned (Beta 1)

2.2 Reference

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

The snapcraft build/packaging meta-data for these can be found on GitHub.

2.2.1 Lime Suite

Lime Suite driver and utilities only.

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

2.2.2 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.

2.2.3 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.

2.2.4 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.
