GPS

In the years to come the evolution of Global Navigation Satellite Systems (GNSS) is tremendous: we will have four GNSSs plus a number of Regional Navigation Satellite Systems (RNSS).This evolution opens the door for a much wider range of high-demanding applications. Examples of challenging (new) GNSS applications are:

  • Earth observation and geo-information
  • space applications,
  • scientific applications
  • safety of life applications

These applications are especially challenging in terms of the performance requirements to be fulfilled. The key performance parameters are precision, integrity and availability. Additionally, many applications require near real-time position determination. Needless to say that ideally this should all be possible anytime and anywhere on Earth. This has triggered a large research interest in the Precise Point Positioning (PPP) technique, which is lean on infrastructure demand. It allows for precise positioning without the need for a (nearby) reference station. The (network) Real-Time Kinematic (RTK) technique is still the option of choice in case real-time positioning down to cm-level accuracy is required.

It is the aim of our research to enable and demonstrate the potential of GNSS by developing theory and algorithms, which contribute to meeting and assessing the performance requirements.
