Time pulse: The time pulse function provides a one pulse per second (pps) signal. Once
the sensor has received any GNSS signals information, the 1 pps signal will adjust to
each second, and the rising edge of each pulse will align to the top of GPS time seconds.
The duty cycle is 10%, meaning the pulse width is 100 ms. The timestamp message is
available in the raw GNSS1 output on port 20010. Some devices require an NMEA-GP-
RMC message along with the time pulse. If this is the case, please get in touch with
Fixposition directly.
Time mark: The time mark accurately measures the time a pulse is detected on pin 6
and outputs a timestamp message on port 20010. At most, the maximum time mark
frequency is 5 Hz.
