Lassen-SK8 Embedded GPS Module A-51
Trimble Standard Interface Protocol
A.17.47 Command Packet 0x6E — Set or Request Synchronized Measurement
Parameters
Packet 6E sets or requests the Synchronized Measurement parameters. The synchronized
measurement parameters are sent by the GPS receiver in Packet 0x6F
Enable / Disable Synchronized Measurements
Controls whether synchronized measurements will be output at the output interval
*
Note – Synchronized Measurement outputs will only be available after the GPS receiver
has made a position fix once the receiver is turned on or reset by Command Packet 0x25.
This ensures that information within the Synchronized Measurement packet will be valid.
Output Level
The period of the Synchronized Measurement outputs is synchronized to the GPS time of
the week. For example, outputs occur when the GPS time of week equals (INT*N), where
INT is the selected output interval and N is an integer.
Two forms of this packet are shown in Table A-54 and Table A-55. The response for both
forms of this packet is Packet 0x6E, Synchronized Measurement Parameters.
