The one-pulse-per-second output is provided for applications requiring precise timing 

measurements. The output pulse is 1usec in duration. The rising edge of the output 

pulse is accurate to +/-1usec with respect to the start of each GPS second. The 

accuracy of the one-pulse-per-second output is maintained only when the receiver has 

valid position fix. 

 

 

 
By using differential GPS (DGPS) correction data in RTCM SC-104 format with message types 
of 1, 2, 3, and 9, position accuracy of less than 5 meters can be achieved. RXD1, pin-8 of the 
10-pin Molex connector shown in figure 2, or pin-11of the 16-pin header shown in figure 3,is 
used as the DGPS input. Differential correction is applied automatically when the correction 
data is received at 9600baud.
