ENTERING COMMANDS

To open a serial port to communicate with th e receiver, complete the following. See also Using CDU, later in this guide.

1. Launch CDU from the Start menu folder specified during the installation process. The default location is Start | Pro grams | NovAtel OEMV | OEMV PC Software.

2. Select Open.... from the Device menu.

3. Select the New... button in the Open dialog box.

4. Enter a name for the new device configuration in the Name field of the New Config dialog box.

6. Select the PC serial port the FlexPak is connected to from the PC Port drop-down list.

7. Select 57600 from the Baud Rate list.

8. Uncheck the Use hardware handshaking checkbox.

9. Select OK to save the settings.

As CDU establishes the communication session with the receiver, a progress box is displayed.

Once CDU is connected, the progress box disappears and several windows open, including the Console window. CDU is now ready to be used to view status information, enter commands, or log data.

USING CDU

CDU provides access to key information about your receiver and

its position. The information is displayed in windows accessed from the View menu. For example, select Position Window from the View menu to display the position solution of the receiver. To show details of the GNSS and geostationary (SBAS) satellites being tracked, select a Tracking Status Window (GPS or GLONASS) from the View menu. Select Help from the main menu for more details on CDU, its windows and features.

DETERMINING WHEN THE POSITION IS VALID

When the receiver has a valid position, the Solution Status field in CDU’s Position window shows Computed.

The OEMV family receivers use a comprehensive command interface. Commands can be sent to the FlexPak using the Console window in CDU, which is opened from the View menu. Enter commands in the text box at the bottom of the Console window.

The following information is important when entering commands:

• Commands can be entered in three formats:

• ASCII (log bestposa)

• Abbreviated ASCII (log bestpos)

• Binary (log bestposb).

Abbreviated ASCII is the best format to use when you wish to work with the receiver directly. For data collection, use ASCII or Binary.

• Press the Enter key to send the command string to the receiver.

• The commands are not case sensitive.

The OEMV Family Quick Reference Guide provided with the receiver lists the available commands and the parameters they use for the Abbreviated ASCII format.

10. Select the OK button to close the New Config dialog box and create the new device configuration.

11. Select the new configuration from the Available device configs list in the Open dialog box.

12. Select the Open button to open communications with the FlexPak.

LOGGING DATA

ENABLING SBAS POSITIONING

ENABLING L-BAND POSITIONING (FlexPak-V1 only)

An extensive collection of logs has been created to capture the data your FlexPak receives and processes. These logs can be directed to any of the FlexPak’s serial ports and can be automatically generated when new or changed data becomes available or at regular intervals. The available logs are listed in the OEMV Family Quick Reference Guide.

To log data, use the LOG command. For example, to log the pseudorange position to COM 2 every 30 seconds, enter the following:

LOG COM2 PSRPOS ONTIME 30

Logs can be generated in one of three formats: ASCII, Abbreviated ASCII, or Binary. Refer to the OEMV Family Firmware Reference Manual (OM-20000094) for information on the LOG command, specifying the output format, and the detailed contents of each log.

If you prefer, CDU provides a graphical interface for configuring data logging. Select Logging Control Window from the Tools menu. In the Logging Control window, you can select which logs to capture and choose to which ports to send the data. In addition, you can specify a file in which to save the data.

FlexPak-V1/V1G/V2 models are also capable of SBAS positioning. This positioning mode is enabled using the SBASCONTROL command. The following commands are typically used to enable WAAS (North America) and EGNOS (Europe) respectively:

SBASCONTROL ENABLE WAAS SBASCONTROL ENABLE EGNOS

Once enabled, the Position Type field shown in CDU’s Position window should change from Single to WAAS and you may see SBAS satellites in the Constellation window.

L-Band equipped receivers allow you to achieve sub-meter accuracy . To use this positioning mode, you must enable L-b and tracking to the Canada-Wide Differential GPS (CDGPS) or OmniSTAR signal. A subscription to OmniSTAR is required to use the OmniSTAR service (visit http://www.omnistar.com have your receiver’s serial number ready). The CDGPS sig nal is free and available without subscription over North America ( visit

http://www.cdgps.com

The ASSIGNLBAND command allows you to set OmniSTAR or CDGPS base station communication parameters. It should include a relevant frequency and data rate. The frequency assignment can be made in Hz or KHz. For example:

Hz: assignlband omnistar 1536782000 1200 KHz: assignlband omnistar 1536782 1200

A value entered in Hz is rounded to the nearest 500 Hz. To confirm you are tracking an L-Band signal, log the L-Band

status information by entering:

log lbandstat

For example, if you are receiving CDGPS, the fifth field after the header should be 00c2:

lbandstata com1 0 43.5 finesteering 1295

149951.671 00000000 976f 34461; 1547546977 46.18 4541.0 0.00 00c2 00f0 ...

and

To specify the correction source, use the PSRDIFFSOURCE command as shown in the examples below:

PSRDIFFSOURCE OMNISSTAR or, PSRDIFFSOURCE CDGPS

otherwise it is left at the default AUTOMATIC.

 Refer to the OEMV Family Firmware Reference Manual for more

on individual L-Band (FlexPak-V1 only), GLONASS (FlexPak-V1G or FlexPak-V2) or SBAS commands and logs.

REAL-TIME KINEMATIC (RTK) POSITIONING

Corrections can be transmitted from a base station to a rover station to improve position accuracy. The base station is the GNSS receiver which is acting as the stationary reference. It has a known position and transmits correction messages to the rover station. The rover station is the GNSS receiver which does not know its exact position and can receive correction messages from a base station to calculate differential GNSS positions.

In most cases you need to provide a data link be tween the ba se station and rover station (two NovAtel receivers) in order to receive corrections. SBAS and L-Band corrections can be accomplished with one receiver and are exceptions to the base/ rover concept. Generally a link capable of data throughput at a rate of 9600 bits per second, and less than 4.0 s latency, is recommended.

Once your base and rover are set up, yo u can configure them for RTCA, RTCM, RTCMV3, CMR+ or CMR corrections. An RTCM example follows (replace the latitude, longitude and height coordinates shown with those of your base):

Base

interfacemode com2 none rtcm off fix position 51.11358042 -114.04358013

1059.4105 log com2 rtcm3 ontime 10 log com2 rtcm22 ontime 10 1 log com2 rtcm1819 ontime 1 log com2 rtcm1 ontime 5

Rover

interfacemode com2 rtcm none off

RT-2 (OEMV-2) and RT-20 (OEMV-1, OEMV-1G and OEMV-2), all with AdV ance R TK, are real-time kine matic software prod ucts developed by NovAtel. Optimal RTK performance is achieved when both the base and rovers are NovAtel products. However, AdVance RTK will operate with equipment from other manufacturers when using RTCM messaging.

RT-2 and RT-20 are supported by GPS-only and GPS+GLONASS OEMV-based models. Also, RT-20 with GPS+GLONASS provides faster convergence.

 1. Refer to the GPGST log’s usage box in the OEMV Firmware

Reference Manual for a definition of RMS and other statistics.

POST PROCESSING

Post-mission data processing refers to when the GNSS data collected by the receiver is processed after the entire datacollection session is complete.

OEMV-based output is compatible with post-processing software from the Waypoint Products Group, NovAtel Inc. For details, visit our website at:
