Managing Prego Memory

When using your Prego in static or dynamic applications, it is useful to know
the amount of memory occupied by the receiver's log file. The specific memory
size depends on the type of data being recorded. Use the formulas below to
compute the approximate size of the receiver's log files.

• N – the number of observed satellites per epoch.
