SDR Satcom Applications
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.
Categories
There are currently two categories of application:
- Community contributed apps
- Reference apps provided by Lime Micro
Community
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.
WeatherDump
WeatherDump is multi-platform software for record, demodulate, decode and processing of data from weather satellites.
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) |
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.
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.
