06-GPS is the first independent company in The Netherlands with a nation wide network of GNSS reference stations, since January 1st 2003.
As a customer of this network you can nowadays survey throughout The Netherlands, Belgium and Luxembourg at the highest level of accuracy with only just one GNSS receiver. Many engineering companies, governmental institutions, public utilities and contractors save time and money every day by working with their GNSS receiver in combination with the network of 06-GPS.
GNSS Network
A total of more than 130 reference stations form the network of 06-GPS, covering the Benelux and parts of the North Sea. All these locations GNSS antennas have a free horizon and so all available satellites are observed. Also all equipment is placed within a building in a protected and secured locker.
The exact coordinates of all reference stations of 06-GPS and of the partners connected into the network of 06-GPS can be found on the downloads page.
Real Time Kinematic, Network DGNSS and Post-processing Services.
The Real Time Kinematic method is suited for surveying with cm accuracy using GNSS. With a single receiver the accuracy would be several metres at best due to the influences of atmospherical disturbances and satellite orbit errors. However surveying relative to GNSS base receivers on know positions makes it possible to reach centimetre accuracy. The method used by 06-GPS consists of sending the GNSS receiver (rover) a correction by mobile internet every single second. These corrections result from an error modelling by which several reference stations are taken into account and can be combined with the GNSS observations of the rover to eliminate the positioning errors.
For decimetre accuracy there is the DGNSS (a differential GPS) service. This network service sends less complicated corrections which can be processed by cheaper GNSS equipment to a position accuracy on decimetre level.
Surveying relatively in regard to other reference stations can also be done afterwards. This is called post processing. Logged GNSS data of an unknown position is combined with data from a known position (reference station). 06-GPS logs all raw data of all reference station continuously so this information can afterwards be used for post processing. Other applications beside land surveys are aerial photogrammetry and remote sensing.
Required rover specifications
A GNSS RTK rover needs to meet a number of specifications to be able to function within the 06-GPS network. In general every modern receiver meets these requirements and can be used.
The required specifications are:
- 24 channel (12+12) L1/L2-frequency receiver. With a L1 only receiver the required accuracy is not achievable.
- RTK functionality of the firmware. The software of the GNSS receiver needs to be able to process corrections of the RTCM V2.x of V3.x type.
- Communication between the GNSS receiver in the field and the 06-GPS computing centre needs to take place by mobile or satellite internet. The GNSS receiver or the controller (fieldbook) needs to have NTRIP functionality.
- Procedure
With the links below you can download all information about subscriptions and prices.
In the price list are 3 different RTK subscription types enabling you to optimize the 06-GPS network availability to your own needs and application. A separate subscription is needed for each rover.
It is possible to test the 06-GPS network at a reduced rate with a once only 1 month RTK test subscription.
After applying online or completing the subscription forms, scan and e-mail it to 06-GPS, you can start your survey the same day!

RINEX and Virtual RINEX Webservice
For the Online supply of RINEX and Virtual RINEX data you can use the 06-GPS RINEX Webservice. This shows you the availability of the RINEX data and offers graphical and alphanumerical tools to select (virtual) reference station(s), periodes and timespans to enable easy and speedy download of the needed data. The Webserver supports several formats, data compresion methods and file naming conventions.
For being able to download data from the RINEX webservice you can request a username and password by applying online or fill in and send the Application Form 06-GPS RINEX Webservice.
