At Delft University of Technology (DUT) a software suite has been developed
for Continuously Operating GPS/GLONASS Reference Stations. The most
important features of this software suite are
- real-time GPS receiver interface (AOA Turbo Rogue family, Javad Positioning
  System, Trimble 4000SSI(E), Trimble 4700, Leica) 
- real-time integrity monitoring
- data storage on hard disk
- communication with remote computing centre
- interface for meteo sensors
The sample rate of the receiver and the transmission rate to the external
computing centre can be selected independently, and the data is sent in
discrete batches of several minutes up to 24 hours, or continuously.

The real-time quality control and integrity monitoring is based on a
single channel approach. It uses a Kalman filter based Detection, Identification
and Adaptation (DIA) procedure.  

The software has been used since 1997 for the Dutch Permanent GPS Network
and since 1999 for DUT's IGEX GPS/GLONASS reference station.
