B.35 SATLIMIT Set Minimum Satellites in Position Solution
The satlimit command allows you to set the minimum number of SVs used in the position solution, for
a specific set of messages to be passed through a particular FILE_n virtual channel.
The following messages are affected by the satlimit filter:
• BESTPOS
• BESTVEL
• MATCHEDPOS
• MARKPOS
• PSRVEL
• RANGE
• RANGECMP
• RTKPOS
• RTKVEL
The satlimit filter does not guarantee that every message in the above list which passes through this
filter is forwarded/rejected as desired. As the tracking environment changes on the GPS receiver, there
is an approximately 2 second delay between the time that a change occurs in the number of SVs used
n position solution and the time that the filter reflects this change. Consequently, during this short
period messages may be incorrectly forwarded or rejected.
The satlimit set command sets the minimum number of SVs for the specified channel(s) to minsv. The
satlimit configuration for a particular channel can be set before or while the channel is associated with
a logfile. The satlimit configuration for a particular channel is cleared when that channel’s association
with a logfile is terminated via the logfile command.
The satlimit default command sets the satlimit value for the specified channel(s) to 0.
The satlimit clear command sets the satlimit value for the specified channel(s) to 0.
