Setting the Base as an NTRIP Server

This page is an abridged version of the Base Setup-Full Setup page in which only the settings required to configure a base as an NTRIP server are presented. The base can serve as an NTRIP server for two external NTRIP casters, possibly delivering different data to each of the NTRIP casters, or for the embedded NTRIP caster.

 

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.

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

GPS

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

GPS

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

QZSS

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

QZS

GALILEO

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

GAL

NTRIP Server 1

Use this area to declare the type of connection used by the base to deliver its data to an NTRIP caster via a mobile communication network (port E) or directly through the Internet (port P). See the description of each parameter in the table below.

 

Parameter

Designation

$PASHS

Connection

Choose the type of network connection used in the re­ceiver to connect to the NTRIP caster:

   External NTRIP Caster via Modem: The base is connected to the Internet via its internal modem used in GPRS mode (port E used).

   External NTRIP Caster via Ethernet: The base is directly connected to the Internet through its Ether­net port (port P used).

   Embedded NTRIP Caster: (Available only if the NTRIP caster option is installed): The base delivers its data to the embedded NTRIP caster.

MDM,..

NTR,PAR

Connect Now

Check this button to let the receiver perform the re­quested network connection after you have clicked on the Configure button.

 

Address, Port, Mount Point, Pass­word

Enter the network information relevant to the NTRIP caster to which the base is expected to deliver its data.

When the base delivers its data to the embedded NTRIP caster, there is no password or IP address needed. You only have to choose the mount point through which the data from the base will be made available to users through the NTRIP caster.

 

Message

Choose the type of message generated by the base.

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

NTRIP Server 2

Use this area to declare the type of connection used by the base to deliver its data to a second NTRIP caster, directly through the Internet (port Q). See the description of each parameter in the table below.

 

Parameter

Designation

$PASHS

Connection

Choose the type of network connection used in the re­ceiver to connect to the NTRIP caster:

   None: No connection to an NTRIP caster required

   External NTRIP Caster via Ethernet: The base is directly connected to the Internet through its Ether­net port (port Q used).

   Embedded NTRIP Caster: (Available only if the NTRIP caster option is installed): The base delivers its data to the embedded NTRIP caster.
