Navigation satellite selection using neural networks
Neurocomputing, 1995 Abstract The application of neural networks to optimal satellite subset selection for navigation use is discussed. The methods presented in this paper are general enough to be applicable regardless of how many satellite signals are being processed by the receiver.

Satellite Selection in the Operational GBAS Context [PDF]
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2017 When incorporating multiple constellations into future Ground Based Augmentation Systems (GBAS) a problem with limited VDB (VHF Data Broadcast) capacity might arise. Apart from that, the number of airborne receiver tracking channels could be insufficient to use all satellites in view as well.

Satellite selection method considering satellite movement in Low-Earth-Orbit satellite networks [PDF]
Satellite selection method considering satellite movement in Low-Earth-Orbit satellite networksLow Earth Orbit (LEO) satellite networks offer low latency and high bandwidth connections, but frequent handovers can degrade communication quality [1]. Besides, since LEO satellite networks are not standardized and are developed independently by individual companies, route selection methods are kept secret. For this reason, most of the studies to date

Performance-Based GNSS Satellite Selection: A Linear Matrix Inequality (LMI) Approach
Navigation, 2023 In the multi-GNSS era, the observable satellites are more than needed and the benefit of processing more than enough satellites is marginal. It is thus desired to select a subset of satellites so that the receiver operation complexity and navigation ...
