Page 21: High Precision Timing Setting
5.1 High Precision Timing Setting High precision timing is based on the fixed position (i.e., the receiver antenna is installed in a fixed position) to provide a stable and reliable timing output. UT4B0 supports three timing modes: fixed-location timing, optimized-location timing, and positioning timing. - Page 22 UT4B0 User Manual positioning accuracy, the timing accuracy in this mode is slightly lower than that of fixed- location timing. The commands to enter the precision coordinates to the receiver are as follows to provide high-precision time service when the precision coordinates are known:...
