APPENDIX Adding Internal Radio Frequencies In this appendix: B Adding receive frequencies for the 450 MHz internal radio If you have installed the optional internal 450 MHz radio in your GPS receiver, use the ‘Win Flash utility to add the relevant receive frequencies to the default list of frequencies. To install the Win Flash utility, see Installing the ‘Win Flash utility, page 140.
€ Adding internal Radio Frequencies 136 Adding receive frequencies for the 450 MHz internal radio L Start the Win Flash utility. The Device Configuration screen appears. From the Device type list, select the appropriate receiver. From the PC serial port field, select the serial (COM) port on the computer that the receiver is connected to. Click Next. The Operation Selection dialog appears. The Operations list shows all of the supported operations for the selected device.
APPENDIX eremite Real-Time Data and Services In this appendix: The RT Streamed Data service is available only with the SPS850 Extreme GPS receivers. It is required on any GPS receiver that will be incorporated into a Tremble Virtual Reference Station (VRS) network. m RT Streamed Data service By default, the Binary Output option is not enabled in the GPS receivers. The option must be enabled before RT messages can be streamed from the receiver. To enable the option, please contact you local Tremble dealer.
138 Real-Time Data and Services RT Streamed Data service An RT service provides GPS observations, shepherdesses, and other information, as defined for that service. When a “client” connects to the service, all data flow is from the receiver to the client. Using the keypad and display to configure RT outputs You can configure RT output during the base and rover setup using the keypad and display. See Outputting corrections, page 65.
APPENDIX Upgrading the Receiver Firmware In this appendix: m The Win Flash utility mB Upgrading the receiver firmware m Forcing the receiver into Monitor mode The GPS receiver is supplied with the latest version of the receiver firmware already installed.

Based on the selections shown above, the Software Upgrade window appears and shows the status of the operation ( for example, Establishing communication with . Please wait.). 8. Click OK.
APPENDIX rrr Troubleshooting In this appendix: Use this appendix to identify and solve common L problems that may occur with the receiver. m Receiver issues Please read this section before you contact Technical Support.
F 144 Troubleshooting Receiver issues This section describes some possible receiver issues, possible causes, and how to solve them. Issue Possible cause Solution The receiver does External power is 100 Check the charge on the external battery and, if applicable, not turn on. Tow. check the fuse. Internal power is too low. External power is not properly connected. Faulty power cable. Receiver does not Insufficient memory. jog data. Data Logging option is disabled.
Troubleshooting F The base station receiver is not broadcasting. Rover receiver is not receiving radio. Possible cause Port settings between reference receiver and radio are incorrect. Corrections are routed to a port rather than to the internal radio modem. A rubber duck antenna is connected directly to the radio antenna port on the receiver, or an external high-gain antenna is connected via cable to the radio antenna port on the receiver.
F Troubleshooting Issue Possible cause Solution The receiver snot The GPS antenna is Make sure that the GPS antenna cable is tightly seated in the receiving satellite connected to the wrong GPS antenna connection on the receiver and not connected signals antenna connector. to the wrong / radio antenna connector. The GPS antenna cable is Make sure that the GPS antenna cable is tightly seated in the noose. GPS antenna connection on the GPS antenna. The cable is damaged.
Glossary almanac Auto Base base station BIN EX broadcast server carrier carrier frequency carrier phase cellular modems CMR CMDR covariance A file that contains orbit information on all the satellites, clock corrections, and atmospheric delay parameters. The almanac is transmitted by a GPS satellite to a GPS receiver, where it facilitates rapid acquisition of GPS signals when you start collecting data, or when you have lost track of satellites and are trying to regain GPS signals.
Glossary datum deep discharge DIPS differential correction differential GPS DOP dual-frequency GPS EGOS elevation mask ellipsoid hemispheric / shepherdesses Also called geodetic datum. A mathematical model designed to best fit the gelid, defined by the relationship between an ellipsoid and, a point on the topographic surface, established as the origin of the datum.
Glossary epoch feature firmware ONASSIS GNUS GOOF HOP L1 L2 Ls Moving Base MASS multi path AMEN Arsonist The measurement interval of a GPS receiver. The epoch varies according to the measurement type: for real-time measurement it is set at one second; for post processed measurement it can be set to rate of between one second and one minute. For example, if data is measured every 15 seconds, loading data using 30-second epochs means loading every alternate measurement.
Glossary POP post processing real-time differential GPS rover Roving mode RT CM RTK BASS signal-to-noise ratio sky plot SNR triple frequency GPS UTC Position Dilution of Precision. POP is a DOP value that indicates the accuracy of three-dimensional measurements. Other DOP values include DOPE (vertical DOP) and HOP (Horizontal Dilution of Precision). Using a maximum POP value is ideal for situations where both vertical and horizontal precision are important.
WAS GS-84 Glossary Virtual Reference Station. A VRS system consists of GPS hardware, software, and communication links. It uses data from a network of base stations to provide corrections to each rover that are more accurate than corrections from a single base station. To start using VRS corrections, the rover sends its position to the VRS server. The VRS server uses the base station data to model systematic errors (such as ionospheric noise) at the rover position.
