Jupiter 3-30
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 3-30 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 3-30 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 3-30.
Porta: NMEA, 9600 bps, 8 data bits, no parity, 1 stop bit
PortB: SiRF Binary, 38 400 bps, 8 data bits, no parity, 1 stop bit

Datasheet
description
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)
yes = always enabled a = available, but not enabled by default
