Report Packet 0x6D - All-In-View Satellite Selection
This packet provides a list of satellites used for position fixes by the GPS receiver. 
The packet also provides the PDOP, HDOP, and VDOP of that set and provides the 
current mode (automatic or manual, 3-D or 2-D). This packet has variable length 
equal to 16+nSVs where “nSVs” is the number of satellites used in the solution.
The GPS receiver sends this packet in response to Packet 
0x
24. The data format is 
shown below. 
Note – The Lassen IQ GPS Receiver sends this packet automatically after a position 
fix or every second if no position fix occurs.
Command Packet 0x7A
The NMEA message determines whether or not a given NMEA message will be 
output. If the bit for a message is set, the message will be sent every “interval” 
second. Use the values shown below to determine the NMEA interval and message 
mask. While fixes are being generated, the output order is: ZDA, GGA, GLL, VTG, 
GSA, GSV, RMC.

Approximate azimuth from true
