A study of the AO-7 eclipse charts for the last 3 years shows a progression toward non-elipse orbits in late 2007 - 2008.
In effect, this means that AO-7 in all probability will not change mode unless anything untoward happens.
It also means that we appear to have a permanent mode-B LEO linear transponder for the forseeable future ... providing operators follow the recommended operating proceedure.
Hi John, I do not believe that is correct, I think that once its non-eclipse that the internal timer will no longer get reset by a eclipse and we will go back to a regular mode A B switch based on that timer...
your thoughts???
