Admin GPS tab improvements:
Galileo sats in alert are removed from the channel after a few seconds.
New priority mode for QZSS. It's been pointed out that because there are relatively
few QZSS sats at present (4 currently) they can be unfairly "locked out" if many
Navstar and Galileo sats are being received and taking all the channels.
If the priority checkbox is set the last two free channels are reserved for QZSS sats.
This number is reduced if sufficient QZSS sats already occupy a channel.
For example if 3 QZSS sats have a channel only one is reserved to try and capture the 4th.
Thanks to Kiwi forum member @fractional_n for the suggestion about QZSS.
I'm not very educated when it comes to GPS stuff (I've read the KiwiSDR design notes as well as the website about the original GPS project that I think inspired the KiwiSDR implementation but that's about it), but I have a question. Does the KiwiSDR download the almanac from the satellites? If so, is there a way it could download it over the internet instead at startup, and if so would that speed up acquisition of satellites? Or anything else it can do since it is has the advantages of internet access and does not need to rely solely on the satellites for data?
