60csx - Flashing Satellite Icons?

[+thefiveofus]

can anyone clarify what the flashing satellite icons mean? I would think they relate to low signal, etc. although I have some that are low signal that don't flash and others that are higher that flash..anyone figure this out? (it's not in the manual as far as I can tell).

 

thx.

The flashing means that the unit is receiving signal from the satellite but has not finished pulling in the data. These flashing satellites will also be represented by hollow signal strength bars the satellite position map rather than solid bars.

thanks...so I wonder how long it takes to get one whole set of data from a satellite...how many digits is it and how long does it take to get a full string? just wondering (e.g. I guess it really doesn't matter)...thanks for the reply, appreciate it...

It won't stop flashing until it has downloaded all the Ephemeris data for that sat. Each sat sends its own Ephemeris data only, you can't get it from any of the other sats. From what I've read, there are three separate 'pages' of Ephemeris data, but I don't know how many bytes are in a single page. However, they update their Epphemeris data once every 30 seconds, so in theory with a good signal you will not need more than 30 seconds to download the data. You might notice a sat flashing for many many minutes, though. This usually happens when it is very low on the horizon, or perhaps because you are getting a lot of multipath reflections causing data errors. In this case, you might have a 'strong' signal, but the bit errors still prevent the GPSr from downloading the Ephemeris data (it won't use corrupted data, so has to again wait for the page to come around again in 30 seconds if it detects a checksum error).
