Foreword Congratulations! Foreword Thank you for purchasing a SMART ANTENNA. Whether you have purchased a stand alone SMART ANTENNA or a development kit, you will find this manual and other companion documentation useful. Please visit our website at www.novatel.com for a complete list of manuals that are available for download. NovAtel’s SMART ANTENNA is a rugged, self-contained GPS receiver and antenna. It is specially designed for harsh tracking environments in a number of applications.
Chapter 1 Introduction The SMART ANTENNA, see Figure 1 below, is a rugged, self-contained GPS receiver and antenna designed for harsh tracking environments. It accepts DGPS correction signals to further enhance accuracy. The SMART ANTENNA provides position and velocity data for a variety of applications.
Chapter 2 Installation This section covers the installation of the SMART ANTENNA. NovAtel’s StarView graphical user interface software running on a PC allows you to control the receiver and to display its outputs. See Section B.2, StarView Software Installation starting on Page 45 for its installation instructions. Details on the StarView program are provided in Reference [5] on Page 12. 2.
Installation Chapter 2 Figure 5: Central Cable Mount 7-pin (shown) or 6-pin connector for the RS-232 12-pin connector for the RS-422 Figure 6: Mounting Holes See also Section A.3, Connector Pin Assignments starting on Page 38 for the connectors’ pin-out descriptions.
Chapter 2 Installation Figure 7: Central Cable Mount Figure 7 shows the SMART ANTENNA with its cable exiting from the central cable mount, see also Figure 5, instead of using the connector shown in Figure 6 on Page 15. Use the open-ended cable shown in Figure 8 to connect the SMART ANTENNA to auxiliary equipment. See Table 2 on Page 17 for the available variations of this cable.

Chapter 2 Installation Figure 10: Magnetic Mount Adapter 2.2 Power/Communication Port The multi-pin connector on the SMART ANTENNA (shown in Figures 5 and 6 on Page 15), acts as both a communication and a power port. Power can be supplied and communication can occur simultaneously using the open-ended SMART ANTENNA cable shown in Figure 8 on Page 16 for the RS-422 or either of the cables shown in the previous section for the RS-232 models.
Installation Chapter 2 By default, the SMART ANTENNA uses satellites above 4.5 degrees elevation. The mask angle can be set to use a different cut-off, as low as zero degrees (all in view), using Message ID# 81, Set Mask Angle (refer to the SUPERSTAR II Firmware Reference Manual for more message details). 2.4 Installation Overview Once you have selected the appropriate equipment, set up your SMART ANTENNA and use it as in Figure 11.
Chapter 3 Operation Before operating the receiver for the first time, ensure that you have followed the installation instructions in Chapter 2, Installation starting on Page 14. The following instructions are based on a configuration such as that shown in Figure 12. It is assumed that a personal computer is used during the initial operation and testing for greater ease and versatility.
Operation 3.1 Chapter 3 Communications with the Receiver Communication with the receiver is straightforward, and consists of issuing commands through the communication ports from an external serial communications device. This could be either a terminal or a PC that is directly connected to the COM1 serial port of the receiver using a straight serial cable.
Chapter 3 Operation The receiver is in Navigation mode whenever sufficient satellite information and measurement data is available to produce a GPS fix. When the receiver has a valid position, the Nav Mode field in StarView’s LLH Solution, or XYZ Solution, window shows Nav 2-D, Nav 3-D, Diff. 2-D or Diff. 3-D. If it shows Initialized there is no valid position yet. The SMART ANTENNA uses a comprehensive message interface. Input messages can be sent to the receiver using the Xmit Msg menu in StarView.
Operation 3.
Chapter 3 3.6.2 Operation Operational States The receiver has 6 operating modes: • Self-Test • Initialization • Acquisition • Navigation • Dead-Reckoning • Fault The receiver switches between modes automatically. The receiver reports the current operating and navigation modes on its host port. 1. Self-Test Mode The receiver enters Self-Test mode upon request from an external source (please refer to Message ID# 51, Initiated BIT Request in the SUPERSTAR II Firmware Reference Manual).
Operation Chapter 3 from the satellite down-link message. After sufficient satellites have been acquired, the receiver enters Navigation mode. In "Search the Sky", the TTFF is typically less than 3 minutes. 4. Navigation Mode The receiver is in Navigation mode whenever sufficient satellite information and measurement data is available to produce a GPS fix. Navigation mode is entered from Acquisition or DeadReckoning mode and exits to Dead-Reckoning or Fault mode.
Chapter 3 3.7 Operation Built-In Status Tests The receiver performs self-tests and generates status information to provide an indication of the operational readiness and to facilitate maintenance actions. The built in test monitors system performance and status to ensure the receiver is operating within its specifications. If an exceptional condition is detected, you are informed through one or more indicators.
Chapter 4 Positioning Modes of Operation The following single frequency modes of operation are described further in this chapter: • Single Point or Autonomous • Optional Satellite-Based Augmentation System (SBAS) Refer to the GPS Overview section in the GPS+ Reference Manual, available on our website at http:// www.novatel.com/Downloads/docupdates.html, for an overview of GPS positioning. 4.
Chapter 4 Positioning Modes of Operation • Receiver Clock Errors – Receiver clock error is the time difference between GPS receiver time and true GPS time. All GPS receivers have differing clock offsets from GPS time that vary from receiver to receiver by an unknown amount depending on the oscillator type and quality (TCXO verses OCXO and so on). • Multipath Signal Reception – Multipath signal reception can potentially cause large pseudorange and carrier phase measurement biases.

Chapter 5 Troubleshooting When your receiver appears not to be working properly, often there are simple ways to diagnose and resolve the problem. In many cases, the issue can be resolved within a few minutes, avoiding the hassle and loss of productivity that results from having to return your receiver for repair. This chapter is designed to assist you in troubleshooting problems that occur and includes resolutions to aid your receiver in becoming operational.
Troubleshooting Chapter 5 • WARNING: Make intermittent problems more repeatable (i.e. by raising operating temperature, varying power supply source, re-orienting hardware placement). Be sure to note what makes the problem worse / lessens the problem. If you are using StarView, ensure the Power Settings on your PC are not set to go into Hibernate or Standby modes. Data will be lost if one of these modes occurs during a logging session.
Chapter 6 Updating Receiver Firmware The software update utility is specially designed to provide an easy way to update your SMART ANTENNA software and model. The software package includes the following items: 6.1 • An update utility, usually called update.
Updating Receiver Firmware Chapter 6 Figure 15: Paste the Registration Key into the DOS Window 6.4 Registration Key Accepted A message confirms the Update software utility activation once the key has been entered, see Figure 16 below. Press any key, for example , to exit. Figure 16: Configuration Accepted 6.5 Starting Software and Options Update Once activated, the Update utility works until the date or session counter expires. Simply follow the instructions on the screen.
Chapter 6 6.5.1 Updating Receiver Firmware Programming Success The Update utility confirms programming success at the end of the programming session, see Figure 18 below. At this point, remove power from your GPS receiver.
