B.36 SITE Control Site Occupations

The site command allows you to control site occupations.

The site enter command defines the site-occupation start time for a site record name. This command does not result in a site record being entered into the logfile – the site record is written to the logfile when the site leave command is received.

The site cancel command cancels a previously-defined site. This command does not delete site records already written to a logfile with previous site enter and site leave commands. Rather, if at a site, as indicated by a preceding site enter command, the site cancel command terminates the site occupation without writing a site record to the logfile.

The site leave command ends occupation of a previously-defined site. If at a site, as indicated by a preceding site enter command, the site leave command terminates the site occupation and write a site record (sitedefb) to the logfile. There is no limit on the number of sitedef logs entered into a single log file.

•The FirstGPSWeek/Sec fields of the sitedef record are set to correspond to the time of the first position log (bestpos, matchpos, range, rangec, rangedelta, rtkdata) received with the number of SVs used in generation of these logs > 0, between site enter and site leave commands.

•LastGPSWeek/Sec fields of the sitedef log are set to correspond to time of the last position log received with the number of SVs used in generation of these logs > 0, between site enter and site leave commands.

•If no position logs are received with the number of SVs used in generation of these logs > 0

between site enter and site leave commands:

•the FirstGPSWeek/Sec and LastGPSWeek/Sec fields of the sitedef log are set to correspond to the times at which the site enter and site leave commands were issued, respectively,

•the SITE_ST_INVALID bit (0x01) is set in the SiteStatus field of the sitedef log

•If no position logs are received with the number of SVs used in generation of these logs > 0 within 30 seconds after a site enter but such logs are received before a site leave command:

•the SITE_ST_STARTTRUNCATE bit (0x02) is set in the SiteStatus field of the sitedef log

•If no position logs are received with the number of SVs used in generation of these logs > 0 within 30 seconds before a site leave but such logs are received at some time after a site enter command:

•the SITE_ST_ENDTRUNCATE bit (0x04) is set in the SiteStatus field of the sitedef log

•If both of the above conditions apply, (that is, if no position logs are received with the number of SVs used in generation of these logs > 0 within 30 seconds after a site enter but such logs are received before a site leave command and if no position logs are received with the number of SVs used in generation of these logs > 0 within 30 seconds before a site leave but such logs are received at some time after a site enter command):
