Add satellites in satmode possible?
Add satellites in satmode possible?
For now there are only a few FM sats in satellite mode,and the satmode solves many problems like doppler,channel saving...
But is it possible to add some SSTV sats in this mode,like no-104,fo-99,sonate...Saving aos and los frequencies is such a big task to me .

The CPS Integration section is what you are looking for.

Do these satellite transmit in normal 25kHz FM? Or are you just going to use the radio for the predictions ?BA7LWX wrote: ↑Tue Nov 16, 2021 2:05 amI found it!Take a chance tonight,thx!N1KY wrote: ↑Mon Nov 15, 2021 5:52 amhttps://github.com/LibreDMR/OpenGD77_Us ... ite-screen

Work in 25khz FM...?Maybe yes, i used to receive the sstv images in frequency mode,so,that will be ok?

Re: Add satellites in satmode possible?
BTW,I wanna ask a question,how does the satmode calculate the doppler affect to frequency?

Re: Add satellites in satmode possible?
It uses the AMSAT "Plan13" algorithm
See
https://www.amsat.org/amsat/articles/g3ruh/111.html
(Only the algorithm implementation, not the BASIC program, because the firmware is not written in BASIC)
