Linux Ubuntu for Radio Astronomy: ACM0 Service for PicoMuon

The error message: means that systemd can’t find a service file named PicoMuonACM0.service. To resolve this, you’ll need to create,

The best image mosaic software for night sky (astrophotography) mosaics depends on your goals, budget, and level of control needed.

Reducing noise in a 1420 MHz radio telescope setup (i.e., for detecting the hydrogen line) involves addressing both internal and

If I use a filter at 1420 MHz that causes 3 dB loss and in amplifier beforehand that gives 3dB

A long Yagi antenna tuned for 1430 MHz can still work at 1420 MHz, but with reduced efficiency and some detuning effects.

TV satellite frequencies in the USA vary depending on the satellite, provider, and whether the service is free-to-air (FTA) or

The amount of sky covered by a radio telescope is typically referred to as its field of view (FoV). Key

These are the results so far of my mapping exercise with the 1.5m parabolic solar cooker dish (LRO-H2): Powerpoint Presentation
