24.1 VIEW function
The appliance starts searching several satellites to find its own position with accuracy:
When satellites have been found, they appear on the pattern; non-locked satellites blink.
The data on the right are:
- the number of locked satellites on the total possible satellites
- the UTC time
- the latitude and longitude of your place
- a table including
the PRN (Pseudorandom Noise)
the identification label of the satellites
the SNR (Signal/Noise Ratio), which means the reception percentage
of the satellite (0% = no signal)
the graphical representation of the SRN.
