You can use the DSN module of the PstRotator program. The program automatically download the necessary files from Horizons and use them to control the rotator and the radio with Doppler corrections.

At this moment the ephemeris are not yet available, but these will be at a short time after a successfully launch.

The step size of ephemeris is 1 minute, but the program will update the az/el and frequency at every 1 second interpolating the info from Horizon files.

Thank you Joe (s) and Brian

Horizons seems the best choice for tracking from a specific location. I quickly changed the target and set my location and it looks good to go.

The AROW visualisation isn't fully up and running prior to launch, but appears to be aimed at the relataive position of the mission to the Earth and Moon.  Still, worth checking after 1817 UTC today. It does have some nice graphics.

Looking at the link budget, the PSK 31 from OMOTENASHI should be receivable with a modest system out to 100,000km. After that antenna gain and noise figure become increasingly important.
Fingers crossed. Lets hope the sticky valve is fixed.

Subject: [AMSAT-BB] Tracking Artemis-1

Does anyone know how to track Artemis 1 during the next few days.?

Tracking the moon is fairly straightforward, but trying to locate the cubesat signals on 70cm during the flight there probably needs some dedicated tracking software.

Maybe some resource online?
