What’s New: A new standard from SAE – “Toughening a PNT system with COTS in-line GPS/GNSS Jamming Protection”
Why It’s Important: Standards can be very effective ways to encourage adoption of beneficial practices.
- Many engineering organizations require adherence to technical standards as a part of their quality control and assured performance programs.
- Following standards can also improve sales and help protect a company from litigation.
What Else to Know:
- This standard admits up front that Controlled Reception Pattern Arrays (CRPAs) can be more effective than in-line. But,
- CRPAs don’t always have the SWAP-C needed by devices and users
- The U.S. restricts sale, and therefore production, of CRPAs because at one time they were seen as military-only items. That is not true anymore, but the rule is still in place. See discussion of this issue in PNT Advisory Board recommendations.
- Most users are still not aware of how vulnerable GPS signals are.
