Compliance with GPS Week Rollover
The GPS week rollover issue refers to the way GPS receivers store information regarding the current GPS
week. According to the official GPS system specifications document (
ICD-GPS-200
, paragraph 20.3.3.3.1.1),
"… 10 bits shall represent the number of the current GPS week…". This means the GPS week is represented by
an integer number between 0 and 1023. As GPS time started on Sunday January 6, 1980 at 0:00 hours, week
1023 ended on Saturday August 21, 1999 at 23:59:59.
As per the GPS system specifications document, NovAtel firmware resets the receiver's GPS week number
back to zero. Users should be aware of this issue and keep in mind that there may be a compatibility issue when
purchasing and using different makes of GPS receivers.

Text surrounded by a box indicates a variable parameter to be entered as part of the command string.
