Setting a Base to Generate Data Streams on its Ethernet Port

This page is an abridged version of the Base Setup-Full Setup page only showing the settings required to configure a base for generating data streams on its Ethernet port (ports I1 to I9).

 

These groups of parameters are detailed below.

Base

Use this area to enter the position of the base.

 

Parameter

Designation

$PASHS

Dynamic

Necessarily static.

DYN

Station ID

Choose and enter a station ID for your reference station, according to the type of differential messag­es it will generate:

   0-1023 (RTCM 2.3)

   0-4095 (RTCM 3.x and ATOM)

   0-31 (CMR & CMR+)

STI

“Get current po­sition” button

Click on this button if you want to allocate the last position computed by the receiver as the reference position for the base. As a result, the Lat/Lon/Height fields below are updated with the coordinates of this last computed position.

CPD,MOD

Latitude

Longitude

Ellipsoid Height

Latitude, longitude and ellipsoidal height defining the reference position of the base. May be entered manually or using the “Get Current position” button.

POS

Antenna

Use this area to define the parameters of the antenna used physically at the base, as well as a virtual antenna if necessary. A virtual antenna may be defined to allow the base to deliver raw data as if it were collected with this antenna.

See the description of each parameter in the table below.

 

Parameter

Designation

$PASHS

Reference Po­sition

Select one of the options below to define the phys­ical location of the base:

   L1 phase center

   Antenna Reference Point (ARP)

   Ground mark

ANR

Measurement Type

Specify the type of measurement (“Slant” or “Ver­tical”) through which the above antenna height was measured.

ANH

Antenna Height

Enter the measured antenna height according to the measurement type used and the selected dis­tance unit.

ANT or ANH

Receiver an­tenna

Select the name of the antenna used at the base. This antenna name can only be chosen from a list of antenna names stored in the receiver.

UNKNOWN, NULLANTENNA, ADVNULLANTEN­NA are special definitions of antennas typically used as virtual antennas.

ANP,OWN

Antenna Radi­us

(Only if “Slant Height” measurement type select­ed). Enter the antenna radius according to the se­lected distance unit.

ANT

SHMP Offset

(Only if “Slant Height” measurement type select­ed). Enter the vertical offset of the Slant Height Measurement Point for the antenna used by the rover. Take care to enter this parameter in the se­lected distance unit. See also the Note below.

ANT

Virtual Antenna

This parameter allows you to define a virtual an­tenna:

   Select “Off” if you do not want to define one

   If you want one, select the virtual antenna name for which you would like the receiver to deliver raw data, i.e. as if the raw data had been collected using this antenna.

This antenna name can only be chosen from a list of antenna names stored in the receiver.

NULLANTENNA, ADVNULLANTENNA, etc. are the most commonly used virtual antennas.

ANP,OUT

Satellites

Use this area to define the constellations tracked by the base as well as the elevation mask applied to all constellations. See the description of each parameter in the table below.

 

Parameter

Designation

$PASHS

Recording and Output Eleva­tion Mask

Enter the elevation mask, in degrees, used by the re­ceiver to determine which raw/differential data from each visible satellite should be recorded or output, de­pending on the elevation of the satellite. No data from any visible satellite located below this elevation angle will be recorded or output.

ELM

GLONASS

Check this button to enable GLONASS tracking (re­quires installed S option). Clear it otherwise.

GLO

SBAS

Check this button to enable SBAS tracking.Clear it otherwise.

SBA

Ethernet Streaming

Use this area to configure the I1 to I9 ports of the receiver as well as the type of data delivered through these ports. Each port can support up to ten connections simultaneously. Define the following parameters for each port:

 

Parameter

Designation

$PASHS

Port Ix

Click this option if the port is to be used. If the port is to be idle, keep the option cleared.

DST

Mode

Specify whether the port will be used in Server or Cli­ent mode:

   In Client mode, you will choose the remote server with which the base will communicate through an IP connection.

   In Server mode, the base will make its output data available for any remote client allowed to communi­cate with it through an IP connection.

DST

Protocol

Specify whether the IP connection will be using the TCP or UDP protocol.

DST

IP Address

If the port is used in Client mode, enter the IP address of the remote server with which the port will communi­cate. This field is irrelevant if you select the Server mode.

DST

IP Port

If the port is used in Client mode, enter the port number of the remote server with which the port will communi­cate. If it’s used in Server mode, enter the port number of the port you are currently setting.

DST

Message Type

Choose from the list below the type of message routed through the port:

   None: no data delivered through the port.

   ATOM

   RTCM3.x

   RTCM2.3

   CMR

   CMR+

Place the mouse cursor over the ”I” sign (to the right of the Message Type drop-down list) to read the details of the currently set messages.
