6.0 Software interface
The host serial I/O port of the receiver’s serial data interface supports full duplex communication
between the receiver and the user.
The default serial modes are as follows:
6.1 NMEA output messages
NMEA is a standard protocol used by GPS receivers to transmit data. Output NMEA (0183 v2.2)
messages for the Jupiter 32 xLP are listed in Table 6-1. A complete description of each NMEA
message is contained in the Navman NMEA reference manual (Part Number MN000315).
6.2 SiRF Binary
SiRF Binary is the proprietary interface protocol of SiRF. It allows the Jupiter 32 a greater level
of configurability and a more standardised message set than NMEA. A complete description of
each binary message is contained in the SiRF Binary Protocol reference manual.
6.3 Software functions and capabilities
Table 6-2 shows the software features available to the Jupiter 32 xLP.

Feature
GGA – global positioning system fix data
GSA – DOP and active satellites
GSV – satellites in view
RMC – recommended minimum specific GPS data
VTG – track made good and ground speed
GLL – latitude, longitude, UTC of position fix and status
ZDA – PPS timing message
A = available, but not enabled by default
Improves position accuracy by using freely available satellite-
based 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
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.
Saves and restores user configurations and preferences to Flash
memory. Refer to Saving and retrieving configuration data to
Flash application note.
Allows easy selection of predefined user/application profiles.
Refer to Jupiter 32 Integrator’s Guide.
