Positioning Application: When using data logging, what is the difference between selecting the 'by channel' option and not selecting it?
Data Logging Enabled
Selecting or deselecting 'By Channel' option
If you leave the 'by channel' option unchecked, you are referring to the Tx ID of a satellite (highlighted in blue in figure 1)
When doing this PosApp will Log data for this SV regardless of which Channel it is on
If you select the 'by channel' option, you are logging data corresponding to an SV on that channel.
In the example below you can see that selecting CHANNEL 3 means you are logging data for SV11 (highlighted in Red in Figure 1)
When doing this PosApp will Log the data for any SV that is on that channel
For example if SV11 moved out of view and SV21 is assigned to channel 3 in it's place, PosApp would then log data for SV21
