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 to provide GNSS data to the International GNSS Service (IGS), EUREF Permanent GNSS Network (EPN), EUMETNET GPS water vapour programme (E-GVAP), and other national and international projects, and to facilitate research and educational applications.

Latest news

Daily RINEX files for a new station, VSLF in Delft, operated by the Van Swinden Laboratory (VSL) of the Dutch Metrology Institute (NMI), has been added to the local data center. VSLF uses a Septentrio POLARX4TR timing receiver with the receiver clock is synchronized with the Dutch timing standard. Only daily RINEX files, from 2012 onwards, are available. [18 January 2018]

GNSS Local Data Center Delft (GNSS-LDC-Delft)

Hourly and daily RINEX data from the Dutch Permanent GPS Array are available through this web site (http://gnss1.tudelft.nl/dpga/rinex) and anonymous ftp (ftp://gnss1.tudelft.nl):

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. 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.

Explanation of the tracking status files.

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: RTCM 3.1
<STA4>00NLD0: RTCM 3.2/3.3 with MSM7 messages
<STA4>00NLD1: RAW data in the receiver proprietary format
The station coordinates in the RTCM messages are in ETRF2000, at epoch 2013-07-02 12:00, see the coordinates and velocities page for more information.

For more information on the data streams in general and their usage see the websites of EUREF real-time, NTRIP, Global list of real-time GNSS data streams from NTRIP and NASA Global Differential GPS system (GDGPS).

Coordinates and velocities

When it comes to coordinates and velocities of the GNSS reference stations there is not a single solution. Coordinates and velocities in various reference frames can be found coordinates and velocities page, with a short explanation.

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.
