Dutch Permanent GNSS Array (DPGA)

The Dutch Permanent GPS Array (DPGA) consists of about 18 continuously operating GPS (and GLONASS) receivers in the Netherlands and a data and computing centre. The main purpose of the network is to facilitate research and educational applications, and to provide GNSS data to the International GNSS Service (IGS), EUREF Permanent GNSS Network (EPN), EUMETNET GPS water vapour programme (E-GVAP), and others.

Latest news

All historic RINEX3 files have been renamed to the new naming convention and moved to the regular ./rinex directory tree. RINEX3 files now use the long names like DLF100NLD_20160610000_01D_30S_MO.crx.gz, the RINEX2 files use the old naming style with short names like dlf10610.16d.Z. Furthermore, highrate and hourly RINEX3 data from before January 1, 2016, have been packed in daily zip files like DLF100NLD_2015256UUUU_01H_10S_MO.crx.zip and DLF100NLD_2015256UUUU_15M_01S_MO.crx.zip that can be found in the regular hourly and highrate RINEX repositories. [2 April 2016]

Three new AGRS.NL stations have been included in the data center. The new stations are: AMEL (Ameland), SCHI (Schiermonnikoog) and TXE2 (Texel). All three stations are located on the Wadden-Islands nearby underground NAP benchmarks. TXE2 is colocated at a tide-gauge. The data is now available from the regular repository [1 March 2016]

IJMU (IJmuiden) and VLIS (Vlissingen), both colocated at tide-gauges, have become part of the EUREF Permanent GPS network. Routine data uploads to BKG and OLG start March 216. [1 March 2016]

Starting March 1, 2016, the RINEX3 file naming convention is used for all RINEX version 3 data (DLF1, WSRA). For instance, the 30 s daily RINEX 3 observation file for DLF1 is now called DLF100NLD_20160610000_01D_30S_MO.crx.gz. The old naming style, dlf10610.16d.Z, is reserved for RINEX version 2 files only. The newly named files will be placed in the regular ./rinex directories. Until the end of March 2016, symbolic links in the ./rinex3 directory using the old naming style will be available to help smooth out the transition. [1 March 2016]

Data in the new RINEX version 3 format is available for a few multi GNSS receivers in the regular rinex directories. RINEX3 files use long file names like DLF100NLD_20160610000_01D_30S_MO.crx.gz, the RINEX2 files use the old naming style with short names like dlf10610.16d.Z.

Receiver specific raw data files are available from within the Internet domain of the Delft University of Technology and for authorized users (who need to login using a username and password), and non-anonymous ftp.

Real-time data streams

Several receivers are currently streaming data using the NTRIP protocol, either in RAW data format, RTCM, or both. For the NTRIP source table see

NTRIP source table (http://gnss1.tudelft.nl:2101)
The naming convention for the mountpoints is
<STA4>0: RTCM3.1
<STA4>1: RAW data in the receiver proprietary format
For more information on these data streams and their usage see the websites of EUREF-IP, NTRIP, Global list of real-time GNSS data streams from NTRIP and NASA Global Differential GPS system (GDGPS).

Contributing networks

The stations are operated by the Delft University of Technology (DEOS) and its partners. The Active GPS Reference System for the Netherlands (AGRS.NL) is a subnet of the DPGA, and NTUS is operated jointly by DEOS and the Singapore Land Authority. More information on the contributing subnetworks and related applications is available on separate pages.

An overview of Permanent GNSS reference stations in the Netherlands is available from here.
