Leica Geosystems introduces the new high accuracy Total Stations: The TM30 and the TS30
LNR NET Reference network
Over the past few years the use of the GPS system for various purposes has shown a tremendous increase. Using a single GPS receiver, the accuracy is still limited to +/- 10m.
If a higher degree of accuracy is desired, surveyors must use 2 receivers. In this manner it is possible to achieve an accuracy with differential GPS (DGPS) of 0,4 - 5 meter and with Real Time Kinematic (RTK) measurements an accuracy of 1cm + 1 ppm.
It is not surprising that the number of DGPS and RTK measurements is steadily increasing. But each time it is necessary to set up and safeguard a reference station.
LNR Globalcom has developed a network of reference stations (LNR NET), whereby a GPS user can access accurate, quality-controlled data 24 hours a day. This allows the user to measure with accuracy while operating only one rover receiver.
Globalcom
From the client's own location, this interface allows the user to select and download RINEX reference data from different reference stations for specific dates and times from the central database of LNR NET, via Internet or via BBS.
Reference Stations
Each reference station registers raw data and RINEX data 24 hours a day for postprocessing and GPS RTK purposes. Each reference station is sending real time data to the network server of LNR Globalcom.
Certification
All of our stations are certified by the dutch cadastre. To download the certificates for each station click here.
LNR NET - GPS RTK RTCM 3.0 via GPRS/GSM
Customers can log in via GPRS or GSM. LNR NET offers various network solutions to the customers.
LNR NET's core is the new and advanced GPS SpiderNET software, with full internet connectivity, from Leica Geosystems.
Running on Microsoft® WindowsTM platforms, GPS SpiderNET enables the reference stations within LNR NET to provide even more comprehensive services than ever before, supplying reliable and accurate GPS data, RTK and DGPS, for the entire country of The Netherlands.
LNR NET, which covers the entire Netherlands, consists of 35 stations owned by LNR Globalcom, 4 stations under contract with Germany (SAPOS) and Belgium (FLEPOS), plus two reserve back-up stations....in total 41 reference stations.
