What’s New: An article by several authors from the European Commission discussing test results for technologies from seven different companies.

Why It’s Important:

PNT services in use today are:
- Essential to most every technology.
- Sourced from GNSS and are vulnerable to a wide variety of threats.
The article shows official recognition of the problem and MAYBE the start of solutions in Europe.

What Else To Know:

Complementing GNSS can be as important as providing a backup. Properly integrated into a receiver, a complementary signal can improve accuracy and enable a user to keep tracking/re-acquire GNSS signals, in addition to providing info when GNSS is not available.
Establishing complementary and backup services can protect GNSS services by discouraging and deterring deliberate interference.
From the article “...there are viable alternatives to GNSS available in the commercial market today.”
The testing was not able to consider many alternative technologies. The article discusses two of these, R-Mode and eLoran.
