1.0 Introduction

Navman’s Jupiter 12 Global Positioning System (GPS) module is a single board, 12 parallel channel receiver that is intended as a component for an Original Equipment Manufacturer (OEM) product. The receiver continuously tracks all visible satellites, providing accurate satellite positioning data. Jupiter 12 is designed for high performance and maximum ﬂexibility in a wide range of OEM applications including handhelds, panel mounts, sensors, and in-vehicle automotive products.

The highly integrated digital receiver uses the Zodiac chipset composed of two custom SiRF devices: the CX74051 RF Front-End, and the CX11577 Scorpio Baseband Processor (BP). These two custom chips, together with memory devices and a minimum of external components, form a complete low power, high-performance, high reliability GPS receiver solution for OEMs. Different module conﬁgurations allow the OEM to design for multi-voltage operation and dead reckoning navigation that uses vehicle sensors in the absence of GPS signals. Each conﬁguration provides different options for different types of antenna connectors (refer to table 1-1).

must be selected at the time of ordering and is not available for ﬁeld retroﬁtting.

The 12-channel architecture provides rapid 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 uses all available information to provide a rapid TTFF.

Acquisition is guaranteed under all initialisation conditions as long as paths to the satellites are not obscured. The receiver supports 2D positioning when fewer than four satellites are available or when required by operating conditions. Altitude information required for 2D operation is assumed by the receiver or may be provided by the OEM application.

The Jupiter 12 receiver decodes and processes signals from all visible GPS satellites. These satellites, in various orbits around the Earth, broadcast Radio Frequency (RF) ranging codes,

timing information, and navigation data messages. The receiver uses all available signals to produce a highly accurate navigation solution that can be used in a wide variety of end product applications. The all-in-view tracking of the Jupiter receiver provides robust performance in applications that require high vehicle dynamics or that operate in areas of high signal blockage such as dense urban centres.

The Jupiter receiver is packaged on a miniature printed circuit board with a metallic RF enclosure on one side (see ﬁgures 1-1 and 1-2). The receiver is available in several conﬁgurations. The conﬁguration and type of antenna connector

Communication with the receiver is established through one of two asynchronous serial I/O ports that support full duplex data communication. The receiver’s serial port provides navigation data and accepts commands from the OEM application in proprietary Navman binary message format. NMEA formatted message protocol is also available with software and/or hardware selection.

Product applications

The Jupiter 12 receiver is suitable for a wide range of modular

OEM GPS design applications such as:

Receiver architecture

The functional architecture of the basic Jupiter 12 receiver is shown in ﬁgure 1-3. The functional architecture of Jupiter 12 DR, with dead-reckoning circuitry, is shown in ﬁgure 1-4.

The receiver design is based on the SiRF Zodiac chipset: the RF1A and the Scorpio Baseband Processor (BP). The RF1A contains all the RF down-conversion and ampliﬁcation circuitry, and presents the In-Phase (I) and QuadraturePhase (Q) Intermediate Frequency (IF) sampled data to the BP. The BP contains an integral
