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.

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.
