public interface GSVSentence extends Sentence
Detailed GPS satellite data; satellites in view, satellite elevation, azimuth and signal noise ratio (SNR). GSV sentences are transmitted typically in groups of two or three sentences, depending on the number of satellites in view. Each GSV sentence may contain information about up to four satellites. The last sentence in sequence may contain empty satellite information fields. The empty fields may also be omitted, depending on the device model and manufacturer.

Example:
$GPGSV,3,2,12,15,56,182,51,17,38,163,47,18,63,058,50,21,53,329,47*73
