Table 4 Overview on two measurement campaigns for the parameter extraction of a multi-satellite LMS model
From: State modelling of the land mobile propagation channel for dual-satellite systems
SDARS measurements(USA, East Coast) | GNSS measurements(Germany, Erlangen) |
|---|---|
High sample rate (2.1 kHz) | Low sample rate (20 Hz) |
→ Reliable for Loo parameterextraction and state parameterextraction | → Reliable for state parameterextraction |
4 satellites (2 GEO from XM, 3 HEO from Sirius) | > 20 satellites (MEO from GPS,GLONASS) |
→ Limited combinations of orbital positions | → Many combinations of orbital positions |
Environments: urban, suburban,tree-shadowed, forest, commercial, highway (open) | Environments: urban, suburban,forest, commercial, open |
Model validation for a limited set oforbital positions | Preliminary state parameters formany orbital positions whichneed refinement and validation |
