Receive (Rover)

After clicking Receive (Rover) and Next, the Positioning window changes to show the Input Source options.

The receiver can be configured to receive three types of corrections: RTK, PPP and SBAS.

RTK

To use RTK corrections, the receiver must have a communications link to an RTK base station. Use the Input Format and Input Ports pages to configure the receiver as an RTK rover.

To enable RTK, select the RTK checkbox and configure the Input Format and Input Ports settings.

To disable RTK, clear the RTK checkbox.

Input Format

Use the Input Format parameters to set the message format for the differential corrections message received from the RTK base station.

Auto

Set the receiver to automatically detect the format of the incoming RTK corrections.

CMR

Set the receiver to accept RTK correction messages in CMR format.

NOVATELX

Set the receiver to accept RTK correction messages in NOVATELX format.

RTCA

Set the receiver to accept RTK correction messages in RTCA format.

RTCM

Set the receiver to accept RTK correction messages in RTCM format.

RTCMV3

Set the receiver to accept RTK correction messages in RTCM Version 3.0 format.

Click the button for the message format to use.

Input Ports

The Input Ports set the communication port, or ports, through which RTK correction messages are received.

Serial Ports

Click the COM buttons to select the serial ports used to receive differential corrections. The number of COM ports available varies depending the type of NovAtel receiver.

When a COM button is selected, the button changes to show a settings icon. Click the settings icon to change the communication parameters used for the COM port. From the COM Configuration window that appears, set the serial communication parameters to match the parameters used by the device to which the receiver is communicating.

Baud Rate

Scroll the list of baud rates and then click a baud rate to select the communication rate (bps) used by this serial port. The default baud rate is 9600.

Parity

Click N, E or O to select the parity used by this serial port.

N = No parity, E = Even parity, O = Odd parity

The default parity is N (No Parity).

Data Bits

Click 7 or 8 to select the number of data bits used for each data message transmitted. The default is 8 bits.

Stop Bits

Click 1 or 2 to select the number of stops bits used for each data message transmitted.

ICOM

Click the ICOM buttons to select the network ports used to receive differential corrections over the receiver's Ethernet connection.

When an ICOM button is selected, the button changes to show a settings icon. Click the settings icon to change the communication parameters used for the ICOM port.

To configure an ICOM port:

1. In the Domain box, enter the hostname or IP address of the device.

2. In the Port box, enter the TCP/UDP port number used by this ICOM port.

3. Click one of the following buttons to select the protocol used by this ICOM port.

   • Disabled – Disable this ICOM port.

   • TCP – Use raw TCP on this port.

   • UDP – Use raw UDP on this port.

4. After setting the communication parameters, click the Done button to save the new settings.

NTRIP

Click the NCOM buttons to select the network ports used to receive RTK corrections. Network ports are used when the receiver is acting as an NTRIP client. The receiver must have an Ethernet connection to use NCOM ports.

When an NCOM button is selected, the button changes to show a settings icon. Click the settings icon to change the communication parameters used for the NCOM port.

To configure a NCOM port:

1. Click the Domain box and enter the hostname or IP address of the Endpoint.

2. Click the Port box and enter the TCP/UDP port number of the Endpoint.

3. Click the Search for Mountpoint button.

4. Click the Mountpoint drop menu and click on the mountpoint to use.

5. Click the Username box and enter the login user name. The username can be up to 30 characters long.

6. Click the Password box and enter the login password. The Password can be up to 30 characters long.

7. To enable GGA output to the NTRIP caster, select the GGA OUTPUT check box.

PPP

To use PPP positioning, a subscription to a correction service (TerraStar or Oceanix) is required. To obtain a subscription, contact your local NovAtel sales representative. The NovAtel product serial number (PSN) is needed to obtain a subscription.

To enable PPP positioning:

1. Select the PPP checkbox.

2. Select the button for the L-Band beam to use.

   If Auto is selected, the receiver searches for multiple L-Band beams on the L-Band channels. If the receiver position is known, the selection criteria is a ranking of granted access L-Band beams by descending elevation angle. If the receiver position is not known, the selection criteria is a ranking of granted access L-Band beams in the order they appear in the stored beam table.

To disable PPP positioning:

1. Clear the PPP checkbox.

SBAS

To enable SBAS positioning on the receiver, select the SBAS checkbox and select the appropriate region on the Region Selection window.

To disable SBAS positioning, clear the SBAS checkbox.

Auto

The receiver automatically determines the satellite system to use based on the receiver's position and prevents the receiver from using satellites from outside of the service area.

EGNOS

The receiver uses only EGNOS satellites.

GAGAN

The receiver uses only GAGAN satellites.

MSAS

The receiver uses only MSAS satellites.

QZSS

The receiver uses only QZSS SAIF signals.

WAAS

The receiver uses only WAAS satellites.
