我在尝试使用 GPS 时收到奇怪的 NMEA 响应:
$GPGSA,A,1,,,,,,,,,,,,,,,*1E
$GPGSV,4,1,16,05,,,,14,,,,11,,,,02,,,*79
$GPGSV,4,2,16,23,,,,28,,,,12,,,,01,,,*71
$GPGSV,4,3,16,32,,,,30,,,,27,,,,26,,,*7A
$GPGSV,4,4,16,21,,,,13,,,,04,,,,03,,,*78
$GPGGA,,,,,,0,,,,,,,,*66
$PQXFI,,,,,,,,,,*56
$GPVTG,,T,,M,,N,,K,N*2C
$GPRMC,,V,,,,,,,,,,N*53
$GPGSA,A,1,,,,,,,,,,,,,,,*1E
$GPGSV,4,1,16,27,,,,03,,,,05,,,,14,,,*7D
$GPGSV,4,2,16,11,,,,02,,,,23,,,,28,,,*71
$GPGSV,4,3,16,12,,,,01,,,,32,,,,30,,,*79
$GPGSV,4,4,16,26,,,,21,,,,13,,,,04,,,*7F
$GPGGA,,,,,,0,,,,,,,,*66
$PQXFI,,,,,,,,,,*56
$GPVTG,,T,,M,,N,,K,N*2C
$GPRMC,,V,,,,,,,,,,N*53
$GPGSA,A,1,,,,,,,,,,,,,,,*1E
它一直这样下去,只改变以 $GPGSV 开头的行中的值。设备是Alienware M14x笔记本中的DW 5620,可以建立3G连接,但不影响上图的响应。输出在室内和室外是相同的。谁能解释这个日志,所以我会知道它是软件问题还是硬件问题?
