Trimble Outdoors SK8 - Manual (Page 172)

C-26 Lassen-SK8 Embedded GPS Module
Trimble ASCII Interface Protocol (TAIP)
The format for using the S qualifier with the TM message is:
>STMAABBCCDDDEEFFFFGGGGGGGGGGG<
Where:
Fields AA through GGGG must be downloaded but the remaining fields may be filled
with zeros (0) to create a total data stream of 28 characters. For warm-start performance,
downloaded time must only be accurate to ±5 minutes so the entire field may be filled with
zeros. However if you wish to specify seconds, use a format such as 08150 to represent
8.15 seconds. The reserved field, GGGGGGGGGGG, should be filled with zeros.
Example:
When the >STM1925000002806199400000000000< message is sent to the GPS receiver,
it specifies that the receiver should set its internal time to 19:25 (7:25 PM) UTC, 28 June
1994. The time downloaded to the receiver should be accurate to ±5 minutes (use UTC,
not local time) for optimum warm start or hot start acquisition.
