NovAtel, L-3 Interstate Electronics Partner on Civil RTK and SAASM Receiver Card

May 30, 2012By

NovAtel Inc. today announced the development of its OEM625S Selective Availability Anti-Spoofing Module (SAASM) GNSS receiver, a collaborative effort between NovAtel and L-3 Interstate Electronics Corporation (IEC). System integrators have come to rely on the centimeter-level positioning accuracy made possible with real-time kinematic (RTK) commercial GPS receivers. Many authorized defense customers rely on access to the Precise Positioning Service (PPS)... read more

Unmanned Air Systems: Precision Navigation for Critical Operations

March 1, 2012By

An alternative precision GPS architecture, Precision RELNAV, enables an airborne tanker plane and a Navy unmanned combat aircraft to navigate independently to a high degree of precision without requiring carrier-cycle ambiguity resolution using precision GPS ephemeris updates to a tightly coupled GPS/inertial solution onboard each aircraft. The solution rivals that of conventional relative kinematic techniques while providing more robust positioning that reduces message traffic between aircraft and does not require a long filtering time. read more

A fuzzy tracking system performs as a narrow bandwidth tracking system in terms of noise reduction, and a wide bandwidth tracking system in terms of dynamic response, overcoming the contradiction between receiver bandwidth requirements using classical tracking techniques for either noise reduction or dynamic tracking. read more
