The G30-L Compact GPS receiver ( data logger ) is about the half size of a
computer mouse. Based on the SiRF star II
TM
chip set manufactured by SiRF
Technology, Inc., G30-L supports all features, and maintains the technical
specifications of the SiRF star II
TM
architecture.
G30-L receiver is a fully self-contained receiver for the Global Positioning System
with data logger capabilities. Inside the container, the TF30 module provides
complete GPS signal processing from antenna input to serial data output. The module
connects seamlessly to low cost active antenna. Moreover, G30-L is also a mini
data logger (up to 15hrs for PVT data, 1Hz update rate) by using SiRF GSP2e
integrated ARM7TDMI
TM
microprocessor and on-board flash memory.
Two versions of G30x are available. G30R comes with a 9-pin serial
connector, and G30U comes with a USB connector. Also both modules can come
with (G30R-L, G30U-L) or without (G30R, G30U) data logger function.
These receivers are well suited to system integrators or users who use popular PC
compatible system, notebook PC, PDA and “off-the-shelf” GPS solution.
G30 can be used as an ordinary real-time GPS locator, and in the mean time to
log the GPS data to its on-board flash memory. The type of data to be logged as well
as the data format can be specified by the user in the logging setup. The log rate is
also user definable. When any of these are activated, the character string is written to
the log file along with the GPS data. A companion software package provides above
functions and replays these markers.
G30 can satisfy a wide variety of application for vehicle navigation, tracking or
leisure purpose. In automotive applications, the SiRF architecture supports advanced
tracking capabilities through fast recovery times combined with reliable operation in
“urban” and areas of dense foliage.
