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. The output NMEA
(0183 v2.2) messages for the Jupiter 30 xLP are listed in Table 6-1. A complete description of
each NMEA message is contained in the Navman NMEA reference manual (MN000315).
6.2 SiRF Binary
SiRF Binary is the proprietary interface protocol of SiRF. It allows the Jupiter 30 xLP 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 30 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
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
Provides an on-demand position fix mode designed to further
improve battery life
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
saves and restores user configurations and preferences to Flash
memory (software version 2.0 and higher)
