SatNOGS: an Open Source Networked Ground Station

SatNOGS

SatNOGS project is a complete platform of an Open Source Networked Ground Station. The scope of the project is to create a full stack of open technologies based on open standards. SatNOGS is a modular and scalable platform designed as a basis of a global network of ground stations. For the first phase of the project we designed, built, coded, documented and successfully tested the hardware and software parts of the platform, that enabled us to real-time track and communicate with satellites.

Shielding EzTV668 receiver

Sunday October 28th, 2012 by Acinonyx

The soldering side does not need any additional shielding since the PCB has a ground copper pour which protects the components from EMI.

The component side can be shielded using aluminum tape or aluminum foil and glue stick (photo #1). I used a small spring, taken from and old battery case, to achieve electrical connectivity between the foil and the PCB ground. The spring was soldered in such a way that it touches the aluminum tape when the casing is closed.

For extra shielding against EMI from the computer itself, I used a USB extension cord on which I added a proper ferrite bead.
