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

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

SDRangel

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

Reference

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

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