CHAPTER 4 OPERATING MODES 4 In this chapter: • Copernicus Receiver Operating Modes • Run Mode • Standby Mode • Monitor Mode • Changing the Run/Standby Modes • 18-Hour RTC Roll Over • Saving Almanac, Ephemeris and Position to Flash Memory • WAAS This chapter describes the primary Copernicus GPS Receiver operating modes and provides guidelines for receiver operation.

4 OPERATING MODES Copernicus Receiver Operating Modes Table 4.1 Copernicus GPS Receiver Operating Modes Operating Modes Run Mode Standby Mode Monitor Mode Description Continuous tracking or normal mode Backup power or low power mode Flash upgrading mode Run Mode The RUN mode is the continuous tracking or the normal mode. Standby Mode The Copernicus GPS Receiver provides a Standby Mode in which the module's RAM memory is kept alive and the real-time clock is running while the rest of the receiver is turned off. RAM memory is used to store the GPS almanac, ephemeris, and last position. Using this information, together with the time information provided by the real-time clock, the receiver normally provides faster startup times. The type of start-up after Standby Mode depends on the state of the receiver prior to entering Standby Mode and on the length of time the receiver spent in the Standby Mode. If the receiver has almanac, ephemeris, and position information before entering Standby Mode, and the time spent in Standby Mode is less than two hours, the receiver will typically perform a hot start. If the receiver has all of the information listed above, but the time spent in Standby Mode is more than two hours, the receiver will typically perform a warm start. The GPS almanac, ephemeris and recent position are automatically stored in nonvolatile Flash memory. Even without time, the receiver can use the information stored in Flash memory to shorten the start-up time. In all cases, the receiver will use all of the available information to do the fastest start-up possible. Note – In the Standby Mode, the power consumption of the unit is very low. See Copernicus Standby Current, page 55. Monitor Mode Monitor Mode is the operating mode for upgrading the firmware stored in the Flash memory. See Chapter 11 for the firmware upgrade procedure. 54 Copernicus GPS Receiver
