Interference Likelihood Mapping with Case Studies

This paper describes a method for mapping interference by using a model of power loss over distance to create a map of the likelihood of the position of the interferer. This paper also includes simulated results and three case studies with live (real-data) interference sources from India, Canada, and Japan....

Demonstrated Interference Detection and Mitigation with a Multi-frequency High Precision Receiver

GNSS interferers come in many forms and classifications. Some are intentional, purpose built in-band jammers, but many are unintentional, originating from sources such as radio, TV, wireless communication and radars...

High-Performance GNSS Antennas with Phase-Reversal Quadrature Feeding Network and Parasitic Circular Array

The antenna is the first component in a positioning
system, which processes the GNSS and correction signals
received from multiple satellites. The precision of a
position is strongly related to the performance of the
GNSS antenna used...
