... Hot Start, that is the start-up sequence of the receiver when the ephemeris, the last position, the time and the almanac information are available. In the RGPSM002, the GPS data structure, including almanac, ephemeris and last position fix, is copied into a specific sector of the on-board Flash memory, that’s the back-up Flash sector, or BBFlash. The data are stored the first time the almanac is complete and up-to-date, then every M minutes, where M is defined in Default Parameters Table *, parameter #37 ...
