11.0 LOGGING SETTINGS
This chapter describes the settings that affect the logging system. These
settings can be configured by using the NMEA protocol.
The log settings are stored in flash memory and thus they will stay valid until the
user reconfigures them.
Logging filters
Logging filters control how often and the amount of time that is stored into the
log. Users may affect the amount of data, and span of time or distance that can
fit into the available memory by using these settings.
Position and interval limits
Users may define the minimum and maximum time intervals, as well as
the movement limits between the storing points:
Minimum interval time (seconds): A new point won’t be added to a log if the
time elapsed since the previous log point is less than the minimum interval
time set. An exception is that if the maximum movement limit is exceeded,
then a new point is logged.
Maximum interval time (seconds): If the time elapsed since the previous log
point is longer than the maximum interval time set, a new point is then logged.
The maximum limit is ignored if it’s set to zero.
Minimum movement (meters): A new point won’t be added to a log if the
distance travelled from the previous log point is less than this limit. An
exception is that, if the maximum interval time from the previous log point is
exceeded, then a new point is logged.
Maximum movement (meters): If the distance travelled from the previous log
point is equal to or more than the maximum value set, a new point is logged. If
the maximum value is set to zero, the maximum limit isn’t used.
