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).
