... , urban planning, renewable and nonrenewable natural resources, archaeology, ecology, urban planning, and agricultural crop management. Precise navigation and timing systems, such as the U.S. Global Positioning System (GPS), the Russian ... significant benefits to agricultural production at a local scale. Precision agriculture is a new technique where farmers integrate their equipment with precise GPS receivers and detailed GIS information about the soils and ...

... is associated with a “systems” process that involves the breakdown of tasks into ever more precise subtasks and then optimization of each activity. The optimized integration of the spacecraft subsystems (propulsion ... . To work properly, observation cameras, telescopes, broadcast or communications antennas, etc. need to be pointed precisely in three-dimensional inertial space. For spacecraft payloads to provide useful services in space, being ...

... , magnetic fields and thermal variations. The mission's star tracker and gyroscopes were the most precise ever designed and produced. GP-B completed its data collection operations and was decommissioned in ... and steady-state Ocean Circulation Explorer. These satellites provide the most precise measurements of the shape of the Earth, critical for precise navigation on land and sea, and understanding the relationship between ...

... craft propulsion systems with special gradations of start and stop capabilities. The recent development of precision-maneuvering and “smart” robotics, exact sensors, new launch and thruster system development, and modular design ... multi-billion dollar industrial sectors represented by satellite communications, remote sensing or space navigation and precise timing applications. But all of these emerging on-orbit servicing operations have significant potential to ...

... actual events. Maybe he strung them together with different characters so they didn't happen precisely the way it would have been described in his novel, but, nevertheless, they were basically ... of the early ‘60s, digital computers were getting faster and they were much more precise, slow but very precise. So then we started marrying analog and digital computers. We used the digital ... 100,000 operations. I've been told that if every component met its reliability specifications precisely, that a typical Apollo flight would have about 1,000 separate identifiable failures. In fact ...

... spinoff from the " Buck Rogers " unit that successfully demonstrated on 1973-74 Skylab missions the precision and control with which an astronaut could maneuver in zero g, would allow Space Shuttle ... , earth rotation, earth tides, and continental drift; and further definition of orbit determination techniques using precision. tracking systems such as lasers and doppler ground stations. All spacecraft subsystems were checked out ...

... . Those techniques also advance us toward human-crew Mars missions, which will need even more precise targeting and heavier landers." The chosen landing site is beside a mountain informally called Mount ... procurement agent for NOAA. Jason-3 is an operational ocean altimetry mission designed to measure precisely sea surface height to monitor ocean circulation and sea level. Jason-3 will follow in ...

... key application satellites that we use for communications, remote sensing, Earth observation, space navigation and precision timing, and weather and climate change monitoring. For many millennia, it was thought that Earth ... and reactive programs. In the United Kingdom, legislative action was taken to institute a terrestrial precise timing synchronization for the Internet. Designers of satellite systems have undertaken the task with the ...

... . “That meant we had to engineer a satellite instrument that not only will collect incredibly precise data, but also will collect more than 250 times as many height measurements as its ... have observed an Arctic sea ice area decline of about 40 percent since 1980, but precise, region-wide sea ice thickness measurements will improve our understanding of the drivers of sea ... issues for navigation and sea ice conditions. “Because ICESat-2 will provide measurements of unprecedented precision with global coverage, it will yield not only new insight into the polar regions, but ...

... : The championship event would mark nearly two decades of U.S. participation in FAI-sanctioned precision acrobatic competitions, first held in 1960 in Czechoslovakia. The event also would commemorate two-thirds ... of small particles; however, engineers had arranged the single-particle impacts to get a more precise understanding of nosecone erosion and its effect on the accuracy of missile and spacecraft trajectories ...
