Title Conexant/Rockwell TU30-D145 GPS module [446]
--------------------------------------------------------------------------------
12 channel GPS module


Conexant/Rockwell TU30-D145-039


Including cable with SMA connector


Has an extra 10kHz clock output.


Works on 5V with passive or active antenna.



Rockwell's Jupiter GPS receiver is a single-board, 12
parallel-channel receiver engine intended as a component
for an Original Equipment Manufacturer (OEM) product.



The receiver continuously
tracks all satellites in view, thus providing accurate
satellite positioning data. It is designed for high
performance and maximum flexibility in a wide range of
OEM configurations including handhelds, panel mounts,
sensors, and in-vehicle automotive products.



The highly integrated digital receiver uses the Zodiac chip
set composed of two custom Rockwell devices: the
"Gemini/Pisces" MonoPacT and the "Scorpio" Digital
Signal Processor (DSP). These two custom chips,
together with suitable memory devices and a minimum of
external components, form a complete low-power, highperformance
GPS receiver solution for OEMs.



Product Overview



The "Jupiter" receiver decodes and processes signals
from all visible GPS satellites. These satellites, in various
orbits around the Earth, broadcast radio frequency (RF)
ranging codes and navigation data messages. The
receiver uses all available signals to produce a highly
accurate and robust navigation solution that can be used
in a wide variety of end product applications.



The "Jupiter" is packaged on a 28 square centimeter
printed circuit board intended for harsh industrial
applications. The receiver requires conditioned DC power
and a GPS signal from a passive or active antenna.



The all-in-view tracking of the "Jupiter" receiver provides
robust performance in applications that require high
vehicle dynamics and in applications that operate in areas
of high signal blockage such as dense urban centers. The
receiver continuously tracks all visible GPS satellites and
uses all the measurements to produce an
overdetermined, smoothed navigation solution. This
solution is relatively immune to the position jumps induced
by blockage that can occur in receivers with fewer
channels.



The 12-channel architecture provides rapid Time-To-First-
Fix (TTFF) under all startup conditions. While the best
TTFF performance is achieved when time of day and
current position estimates are provided to the receiver, the
flexible signal acquisition system takes advantage of all
available information to provide a rapid TTFF. Acquisition
is guaranteed under all initialization conditions as long as
visible satellites are not obscured.



To minimize TTFF when prime power is removed from the
receiver, an external OEM-supplied DC supply voltage is
required to maintain power to the Static Random Access
Memory (SRAM) and to the Real-Time Clock (RTC). In
this case, the shortest possible TTFF is achieved by using
the RTC time data and prior position data stored in the
receiver's Electrical Eraseable Programmable Read-Only
Memory (EEPROM).



The receiver supports Two-Dimensional (2-D) operation
when less than four satellites are available or when
required by operating conditions. Altitude information
required for 2-D operation is determined by the receiver or
may be provided by the OEM application.



Communication with the receiver is established through
two identical, independent, asynchronous serial I/O ports
that support full duplex data communication. The
receiver's primary serial port (the host port) outputs
navigation data and accepts commands from the OEM
application in National Marine Electronics Association
(NMEA-0183) format or Rockwell binary message format.



The secondary port (the auxiliary port) is configured to
accept Differential GPS (DGPS) corrections in the Radio
Technical Commission For Maritime Services (RTCM
SC-104) format (a summary of the supported RTCM
message types is listed in Table 9).
