What is GPS Time / TOW / WNO?
Question:
We assume that a receiver reports time in GPS in GPS Notation (Time
of Week "TOW", Week Number "WNO"). Is it possible to convert this to UTC?
Answer:
The GPS receiver reports in TOW and WNO. Conversion to
UTC is done by adjusting the leap seconds (which is a correction term
that is also transmitted by the GPS receiver). When converting to Date
and Time, care must be taken to handle the Week number roll over
correctly. |
