Report Packet 0x6D - All-In-View Satellite Selection<br />
This packet provides a list of satellites used for position fixes by the GPS receiver.<br />
The packet also provides the PDOP, HDOP, and VDOP of that set and provides the<br />
current mode (automatic or manual, 3-D or 2-D). This packet has variable length<br />
equal to 16+nSVs where “nSVs” is the number of satellites used in the solution.<br />
The GPS receiver sends this packet in response to Packet 0x24. The data format is<br />
shown below.<br />

Command Packet 0x7A<br />
The NMEA message determines whether or not a given NMEA message will be<br />
output. If the bit for a message is set, the message will be sent every “interval”<br />
second. Use the values shown below to determine the NMEA interval and message<br />
mask. While fixes are being generated, the output order is: ZDA, GGA, GLL, VTG,<br />
GSA, GSV, RMC.<br />
