This is the normal case for GX1200 sensors when operating as an RTK rover connected to the Internet using NTRIP services Section 3 describes how to connect a GRX1200 Pro sensor to the Internet as an NTRIP Server This means the GRX1200 Pro sensor is permanently connected to the Internet using the inbuilt Ethernet interface connects to the NTRIP Caster and provides RTK data 2 1 1 Support of GPRS Devices To obtain access to the Internet with a GX1200 sensor GPRS General Packed Radio System de vices will normally be used GPRS is a telecommunication standard for transmitting data packages using the Internet Protocol IP The advantage for the user to use GPRS technology is that charges are made based on the amount of transferred data and not as for normal GSM or CSD Circuit Switched Data communication where charges are made for the connection time regardless of how much data is transferred The telecom provider should be contacted for information regarding costs of receiving data via GPRS System1200 v1 52 firmware allows almost any GPRS capable device to be used which can be config ured using AT commands Either a default GPRS device can be selected to be used or a new device can be created if necessary WORKING TOGETHER Pa Sf FUNCTION Jaf m E Fo N integrated i oa i lt i gt m BU Surveying 4 21 Surveying amp Engineering Division System1200 Using NTRIP via Internet 2 1 1 1 Default GPRS Intern

As already mentioned in section 1 the Mountpoint identifies the NTRIP Server the RIK reference station which provides the RTK data to the NTRIP Caster If the name of the Mountpoint is not known then the NTRIP Source Table can be downloaded to the sensor by pressing the F5 SRCE button the sensor will now connect to the NTRIP Caster and re quest the NTRIP Source Table Note this assumes the sensor is already configured to connect to the Internet see section 2 1 and the correct IP address is already entered in the Set NET port panel see section 2 2 Note after the download of the source table the connection to the NTRIP caster will be automatically interrupted 2 3 2 The NTRIP Source Table The NTRIP Source Table is a list of all available Mountpoints including the properties of all Mount points registered on the NTRIP Caster After pressing F5 SRCE in the above panel and downloading the Source Table the CONFIGURE NTRIP Source Table panel is automatically accessed which shows all available Mountpoints WORKING TOGETHER os FUNCTION P ee integrated i LEICA SYSTEM 1200 BU Surveying 15 21 Surveying amp Engineering Division System1200 Using NTRIP via Internet 16 20 CONFIGURE NTRIP Source Table MountPoint Identifier Frankfurt Helgoland Leipzig Wettzell Move the focus to the required Mountpoint and press F1 CONT to copy the Mountpoint name to the Mountpnt prompt in the NTRIP p

6. RIP SOURCES The NTRIP Server transfers data to the NTRIP Caster see below using TCP IP connection in our case RIK data The NTRIP Server needs to be first accepted by the NTRIP Caster and if authorized can pass RIK data to the NTRIP Caster The NTRIP Source in our user cases this is a GRX1200 Pro sensor configured as an RTK reference station generates the data streams in our case RTK data streams Note the NTRIP server could be the GPS1200 sensor itself This means the GPS1200 sensor is both the NTRIP source generating the RTK data and also the NTRIP server transferring this data to the NTRIP Caster the NTRIP Server This use case is not discussed in these notes Alternatively the NTRIP Server could be a PC using LEICA GPS Spider software this approach then allows the RTK reference station to be remotely controlled The NTRIP Server also sends the identification name of the NIRIP Source the so called Mountpoint and other additional information parameters relating to the Source which identifies the Source to the NTRIP Caster Such additional information may include which RTCM format is transferred or if the Client rover needs to send NMEA positions in order to receive an individualized RTCM stream from a reference station network Before a GPS1200 sensor can stream RTK data to the NTRIP Caster a registration form must be completed this is available from the Caster administration centre See http igs ifag de index_ntr
