Fix, Log and Reporting Rates
The rates at which the TrimTrac 1.5 computes, logs and transmits GPS positions need not
be equal. For instance, the GPS receiver can operate in the background at the maximum
rate of 1 Hz. Fixes are logged each time the TrimTrac 1.5 cycles through the state
machine. Not every position that is logged, however, needs to be transmitted. Each of
these rates are explained in the following sections.
