    The possibility of the USSR's global satellite navigation system GLONASS and the NAVSTAR Global Positioning System using a common navigation system can only be determined following exhaustive testing of two systems in a variety of satellite and receiver modes and configurations. The authors describe their first attempts to carry out basic position-fixing and timing measurements with a single-chann... View full abstract»

    The US Coast Guard entered into an agreement with the Soviet Union for the implementation of a mixed Loran-C/Chayka chain in the North Pacific. The similarities and differences of the US Loran-C and USSR Chayka systems are discussed, and the agreed-on design for a Bering Sea Chain is presented. The chain will provide marine and aviation coverage over the five-hundred-mile-wide coverage gap that ex... View full abstract»

    High-accuracy orbits have been determined for satellites of the Global Positioning System (GPS), with submeter orbit accuracy demonstrated for two well-tracked satellites. Baselines of up to 2000 km in North America determined with the GPS orbits shows daily repeatability of 0.3-2 parts in 10/sup 8/ and agree with very long baseline interferometry (VLBI) solutions at the level of 1.5 parts in 10/s...

    The requirements and design philosophy for developing ground-based automation planning and control advisory concepts to best serve aircraft with flight management systems (FMS) are defined. Analytical results are presented that are based on the comparison of operational data with the user-preferred trajectories to identify flying-time variabilities in various segments of arriving flights. En route... View full abstract»

    Most land vehicles whose positions need to be tracked are made primary of steel. The problem considered is that of finding locations within or on land vehicles where magnetic sensors can be mounted to measure heading accurately and of finding compensation methods that minimize the effect of the vehicle magnetic signature. Results obtained with various types of vehicles in several world locations a... View full abstract»
