Report Packet 0x83 - Double-Precision XYZ Position Fix and Bias
Information
Information
This packet provides current GPS position fix in XYZ ECEF coordinates. If the I/O
Position option is set to XYZ ECEF and the I/O Precision of Position option is set to
Double (see Packet 0x35), the receiver sends this packet each time a fix is computed.
The data format is shown below.
Position option is set to XYZ ECEF and the I/O Precision of Position option is set to
Double (see Packet 0x35), the receiver sends this packet each time a fix is computed.
The data format is shown below.
The time-of-fix is in GPS time or UTC, as selected by the I/O “timing” option.
Packet 42 provides a single-precision version of this information.
Report Packet 0x84 - Double-Precision LLA Position Fix and Bias
Information
Information
This packet provides current GPS position fix in LLA coordinates. If the I/O Position
option is set to LLA and the Precision of Position option is set to Double (see Packet
0x35), the receiver sends this packet each time a fix is computed. The data format is
shown below.

WARNING –
When converting from radians to degrees, significant and readily visible
errors will be introduced by use of an insufficiently precise approximation for the
constant p (PI). The value of the constant PI as specified in ICD-GPS-200 is
