Integrating SAASM GPS and Inertial Navigation: What to Know


December 08, 2017

Don?t underestimate the complexity of integrating SAASM-based GPS into an INS for unmanned vehicle systems or manned portables such as target locators.

At any moment, a mission could be threatened — with potentially severe consequences — because of jamming and spoofing aimed at global navigation satellite systems.

The U.S. government’s mandate that any military GPS system receiver be equipped with a Selective Availability Anti-Spoofing Module (SAASM) microchip helps manage the risk. In the field, however, integration between SAASM, GPS and inertial navigation systems (INS) doesn’t always work as planned.

For manufacturers new to navigation or SAASM, or even for larger companies, knowing the steep integration challenges and considering turnkey solutions can save time and expense and ensure secure operations.
