The Dutch Permanent GPS Array (DPGA) consists of about 15 continuously operating GPS (and GLONASS) receivers 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.
The GPS antenna type at CABW has been damaged and was replaced by a different type. There is a small offset in position and height. [17 March 2012]
Data in the new RINEX version 3 format is now available for a few multi GNSS receivers. The data is served from a dedicated parent directory ./rinex3 with subdirectories for daily (30 sec), hourly (10 sec) and highrate (1 sec, 15 minute files) data. [1 June 2011]
The server has been migrated to a new location and domain: http and ftp services are now provided from gnss1.tudelft.nl. Http connections to the old server (gnss1.lr.tudelft.nl) are re-directed to the new server, however, ftp access is only available through the new server. Our apologies for any inconvenience this may cause. [20 Dec 2010]
A new station VLIE (Vlieland) has been added. VLIE is co-located with a tide-gauge station at the Dutch coast and a primary underground marker from the National height datum (NAP). VLIE is the fourth station that is co-located with a tide-gauge; other stations co-located to tide-gauges are TERS (Terschelling), IJMU (IJmuiden) and VLIS (Vlissingen). VLIE is operated by the Kadaster. [2 Dec 2010]
Data in the new RINEX version 3 format is available for a few multi GNSS receivers. The data is available from a dedicated parent directory ./rinex3 with subdirectories for daily (30 sec), hourly (10 sec) and highrate (1 sec, 15 minute files) data.
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.
Several receivers are currently streaming data for the Real-Time IGS Network (RT-IGS) and EUREF Permanent Network (EUREF-IP). The status of these data streams can be monitored through
DLFT RT-IGS data-stream, WSRT RT-IGS data-stream (RT-IGS @ 1Hz)For more information on these data streams and their usage see the websites of IGS real-time working group, EUREF-IP, NTRIP, Global list of real-time GNSS data streams from NTRIP and NASA Global Differential GPS system (GDGPS).
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.
