GPSMAP65s - Galileo Satellites Flashing [Bug 8]

[skinnie]

Firmware 4.40 finally fixes the issue with flashing satellites for Galileo and GLONASS.
Suddenly a huge number of satellites are acquired shortly after power on.

One year after product release Garmin made the product available which they announced...

Just tried briefly on my balcony and yes it gets fixed without satellites flashing.
Well better late than never!

Hello,
I had sold my 65s because of this flashing and not taking into account the Galileo satellites and I had bought a 66sr which had the same problem, solved for a few days by a new version of the firmware, Garmin takes a long time to modify their products despite pressing demands from their customers. These are the Kings, he only listens to them.

CPE just helps with 'quicker' first fix performance. The GPSr will load the same data from the satellites in view, just slower, so you do not have to have the CPE file for your device to work. It just improves how quickly the GPSr can get its first fix after power-up.

It is true in normal conditions.

But when conditions are particularly bad (eg. inside building) GPSr will be unable to download data from the sky. Sometimes signal from satellite is good enough for GPSr to use it, but to poor to acquired all necessary data directly from it.
In this situation when GPSr has pre-acquired data (like EPO/CPE or cached data), it can still use it.

I have tested this inside building (beside the window), when after several hours my GPSr started losing satellites.
However when I provided fresh EPO/CPE data to it, the number of satellites available increased noticeably and immediately.
