Install satelite keps ?

Post by sp7epj » Mon May 30, 2022 8:14 pm

Hello !

I have a question

How many satellites FM can you enter into the satellite.txt file?

Which is in the installation directory OpenGD77CPS

Max 15 satellites

See

https://github.com/LibreDMR/OpenGD77_Us ... ite-screen

google for how to find the location of an exe application, it will vary depending on Windows version and how you configured your PC

There will be a possibility of more ?

Because there are more and more of these FM satellites

The current list of FM satellites :

AO27,AO91,AO92,CAS3H,IO86,PO101,ISS,SO50,UVSQ,EASAT-2,HADES,TEVEL 1 - 8

I think the limitation is the internal memory to store the predictions for all satellite for 24 hours, and also the increased time it takes to calculate those predictions.

Probably the number could be increased slighly if there were actually more fully operational satellites.

Roger yes I agree

Some satellites operate intermittently or are not yet turned on but are in orbit

But I would increase the limit so that there were no more topics and questions "why so little" :-)

Memory RAM in these radios is very small. 128k in total, and 70% is already used. So perhaps 24k remaing, but not all can be used for Satellite keps, becasue it may need to be used in the future for other functions.

MD9600 has an extra 64k RAM but its not currently used becuase its in a separate bank and will require changes to the source code to possibly make use of it.

Yes it's true

we must use what you give, because what you do with the team is a great job
