METHODS FOR IDENTIFYING WHETHER OR NOT A SATELLITE HAS A LINE OF SIGHT

摘要

The invention, in some embodiments, relates to the field of global navigation satellite systems, and more particularly to the field of methods and devices for identifying whether a satellite in a global navigation satellite system has a line of sight to a specific global navigation satellite system receiver (LOS satellite) or does not have a line of sight to the global navigation satellite system receiver (NLOS satellite).

主权项

1. A method for classifying whether or not multiple GNSS satellites have a line of sight to a GNSS receiver, the method comprising:
receiving signals from a plurality of GNSS satellite; for each satellite of said plurality of GNSS satellites, computing a pseudorange to the GNSS receiver based on at least one of said signals received from said satellite; and using said computed pseudoranges, classifying, for each satellite in said plurality of GNSS satellites, whether: said satellite is an LOS satellite, having a line of sight to said GNSS receiver; or said satellite is an NLOS satellite, not having a line of sight to said GNSS receiver.
