1 Introduction

Here you can find details of the snaps in the SDR Satcom App Store.

2 Categories

There are currently two categories of application:

  • Community contributed apps
  • Reference apps provided by Lime Micro

2.1 Community

2.1.1 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).

2.1.2 SatHelperApp

The OpenSatelliteProject (OSP) Satellite Helper Application is currently an LRIT/HRIT demodulator / decoder program based on libSatHelper and xritdemod.

2.1.3 SDRangel

SDRangel is a Qt5 / OpenGL 3.0+ SDR and signal analyzer frontend. It has support for various modes, including DVB, and transmit operation.

2.2 Reference

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

The snapcraft build/packaging meta-data 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.
