ABSTRACT: Use of an integrated GPS/inertial system can be effective in mitigating the effects of GPS signal interference, such as intentional jamming. Currently the GPS/Inertial Working Group of RTCA Special, Committee (SC)-159 is developing requirements and test procedures for a tightly coupled GPS/inertial system. This paper investigates two of the key issues being addressed by the working group. The first is how well a tightly coupled GPS/inertial system can detect slowly growing errors. The paper investigates this issue for two integrity monitoring methods. The second issue relates to how long the system can coast upon complete loss of GPS signals caused by interference. Using analytic formulas, the paper determines maximum coasting times possible under various scenarios.
