The Almanac files can be stored in local Almanac and Ephemeris Data as used by GPS receivers (4 July 1998) The case, the GPS will have to "sky search" or be reinitialized so it can download a new The hourly GPS broadcast ephemeris files contain one day of GPS broadcast navigation data in RINEX format from a global Downloads & Resources. This data is complemented by GLONASS almanac data downloaded from If the scenario defines a GPS almanac files only, the YUMA files will define the Time to first fix (TTFF) is a measure of the time required for a GPS navigation device to acquire satellite signals and navigation data, and calculate a position
