Over the recent past, the vulnerability of Global Navigation Satellite Systems (GNSS) to interference has become a concerning issue (Mitch, 2011), (Pullen, 2012). Nowadays, illegal portable jamming devices are becoming popular to protect the user from being tracked by GNSS in their vehicle. These so-called personal privacy devices radiate different types of interference signals in the GNSS frequency bands and can make conventional receivers inoperable. Counter measures have to be taken to prevent strong interference from blocking the GNSS-receivers for safety critical applications.
When looking at the timeline of technology of today’s consumer electronics, there are several interesting connections with technology and associated infrastructure originally (at least partly) developed in the cont ext of DoD funded projects. Large-scale integration of this technology into consumer electronics created an economy of scale that is unmatched, enabling capabilities and services that otherwise may have been prohibitive due to cost.
