After a nice code push, scheduling observation functionality is now complete in SatNOGS Network website. The website is now able to dynamically calculate and schedule observation windows given a satellite for all available Ground Stations. The functionality works like this: The observer enters the New Observation page. After selecting a […]

We’ve been thinking for some time that there is no need to install two separate RTL-SDR dongles to cover both VHF and UHF. It increases power consumption on WR703N without actually having any benefit, as using two dongles simultaneously is limited by the CPU power and network bandwidth. A diplexer […]
The SatNOGS Network website has had the focus in terms of development from our software team in the past week. While the major functionality (observation calculation and scheduling) is coming along nicely (thanks to libraries like python-ephem) we are also delivering other needed functionality. This time it was a public, […]
In order to achieve global coverage, a network of Ground Stations would have to have nodes in places that are not entirely friendly environments. Desert hot, ice cold, gusty, monsoon rainy, mountain dry and forest humid could be some descriptions of possible locations SatNOGS would have to survive in. Apart […]
Most of the times you would want your ground station to be stable. Secured on a metal beam on top of a building, protected, homed and zeroed where no-one and nothing could disturb it. That is the ideal situation. For those of us though that like adventures and want to […]
Continuing the development of SatNOGS Network, we focused on enhancing the observation results page. Check out how it looks overall: What is new? Timeline The new timeline view gives a quick overview on the data that each ground station collected within the observation timeframe. On the left you can see […]
An important part of the instrumentation of our ground station is the Antennas. Early on the SatNOGS team designed and constructed 2 Yagis for UHF and VHF bands. The UHF Yagi design was essentially a cross Yagi design trying to address the circular polarization issue. Based on the experimental operation […]
The time we’ve all been waiting for, has come. We are proud to release v2 of SatNOGS Ground Station (Tracking Box) with many upgrades and fixes from the previous version. Notably: Redesigned Axis Gear Assemblies. They are now smaller, more robust and reliable based around a much more powerful NEMA […]
Using the first version of satNOGS hardware we figured out that some times due to various reasons (software, mechanical or power malfunctions) the rotator might end up in an unknown position. At that point, the only way to resolve that situation was to manually reset the rotator to home position […]
Stepper motor and axis movement should be accelerated, decelerated and smooth. This is important for a variety of reasons including less strain on the axis and the gears, plus inertia compensation. Agis with Manthos spend some time looking into some options and finally agreed to implement acceleration resulting to smooth […]
