6.3 Software functions and capabilities
Table 14 shows the software features available to the Jupiter
6.4 Flash programming
The firmware programmed in the Flash memory may be upgraded via the serial port RXA pad D5. The user can control this by
driving the Serial BOOT SELECT high at startup, then downloading the code from a PC with suitable software (SiRFFlash). In
normal operation this pad should be left floating for minimal current drain. It is recommended that in the user’s application, the
BOOT SELECT pad is connected to a test pad for use in future software upgrades.

Description
Improves position accuracy by using freely available satellitebased
correction services called SBAS (Satellite Based Augmentation System)
Improves battery life by using enhanced power management and
intelligently switching between low and full power depending on
the current GPS signal level. Refer to the Low Power Operating
Modes application note.
Provides an on-demand position fix mode designed to further
improve battery life. Refer to the Low Power Operating Modes
application note.
Allows hot start performance at all times including in weak
conditions and moving start ups yes
Improves cold start times by storing the most recent almanac to
flash memory.
Acquires satellites and continues tracking in extremely low
signal environments.
Continues navigating in extremely low signal environments.
A timing signal generated every second on the second.
Sensor based Dead Reckoning without valid GPS signals
Active antenna short circuit and open circuit detection
and control software.
AGPS using predicted ephemeris data.
Allows storage of user commanded receiver configuration changes
to Flash memory.
