System and Service Volume Simulation Environment (S²VSE)
System and Service Volume Simulation Environment (S²VSE)
A modular and flexible simulation environment that enables the DLR Galileo Competence Center to provide analysis and consultation covering a wide range of PNT topics
S²VSE allows the testing and validation of novel system designs and enables technologies by simulating the functional and processing architecture of GNSS. The simulation environment encompasses a system simulator and a service volume simulator.
With an increasing number of newly proposed satellite constellations and extensions to existing system designs it is necessary to be able to effectively create varying single- or multilayer constellations for evaluation.
New constellations are often envisioned in lower orbits, meaning more satellites are needed for global coverage. This creates a large configuration space, making this well-suited for applying optimisation techniques.
GNSS often experiences reduced performance in areas of low visibility like cities. S²VSE enables the creation of realistic user scenarios for the analysis of effects such as shadowing and non-line of sight (NLOS).
Some other Features are…
Receiver grid generation for different scenarios
Orbit propagation including environmental aspects like space weather
Signal-In-Space Ranging Error (SISRE)
User Equipment Error (UEE) and User Equivalent Range Error (UERE)
GNSS based positioning and sensor fusion including quantum sensors
