Command Packet 0x23 - Initial Position (XYZ ECEF)
This packet provides the GPS receiver with an approximate initial position in XYZ
coordinates. This packet is useful if the user has moved more than about 1,000 miles
since the previous fix. (Note that the GPS receiver can initialize itself without any
data from the user; this packet merely reduces the time required for initialization.)
This packet is ignored if the receiver is already calculating positions. The data
format is shown below.
Note – To initialize using the Latitude-Longitude-Altitude representation, use
Command Packet 0x2B.
