Scalable 5800 GPS Survey System

Trimble has introduced a scalable Trimble 5800 GPS System, adding greater flexibility and versatility for a variety of survey, construction, civil engineering, and asset management applications. Surveyors can begin with the L1, postprocessing-only configuration. Two upgrades are available for higher performance: L1/L2, postprocessing only and L1/L2, full Real Time Kinematic (RTK).   The Trimble 5800 System combines a GPS receiver, antenna, UHF radio, Bluetooth wireless technology, and power source into a single compact unit weighing approximately 1.21 kilograms (2.67 pounds). The Trimble 5800 can be configured as a GPS base or rover, making it versatile for the surveyor's project needs.... (read more)

Galileo and GPS Synchronise Watches

To ensure the early interoperability of Europe’s satellite navigation with GPS, the four Galileo satellites have begun broadcasting the ‘offset’ between the parallel navigation systems’ timings, accurate to a few billionths of a second. With satellite navigation based around the highly accurate measurement of signal times, both Galileo and GPS have their own internal reference time systems used to synchronise all system clocks and signals. The problem is that these time systems are not quite identical, with Galileo System Time being around 50 nanoseconds or less apart from GPS time. A nanosecond is only a billionth of a second, corresponding... (read more)

Hemisphere GPS Announces Centimetre Accuracy

From the 2007 ION GNSS Conference, Hemisphere GPS announced the Eclipse dual-frequency GPS receiver technology. Based on Hemisphere GPS' Crescent L1 GPS technology that incorporates techniques for reducing code measurement noise and mitigating multipath signals, Eclipse delivers reliable centimetre-level accuracy.   The Eclipse board allows OEM customers to integrate it into a wide variety of precise applications including navigation and GPS machine control. Depending upon the application, Eclipse users can record and post-process GPS data or choose from several differential solutions including Real-Time Kinematic (RTK), OmniSTAR(R)  (HP/XP) and SBAS (WAAS, EGNOS, etc.).   As a dual-frequency solution, Eclipse receiver technology...

GPS Intellectual Propterty Issue Resolved

The governments of the United Kingdom and the United States of America have reached a common understanding of intellectual property rights related to the Global Positioning System (GPS), and will work together to address broader global navigation satellite systems' intellectual property issues. This understanding is part of a broader shared effort to advance compatibility and interoperability among civil satellite navigation systems and transparency in civil service provision. The two governments affirmed their joint commitment to ensuring that GPS civil signals will remain free and openly available for users worldwide. As part of this effort, the UK is dedicating all government-held... (read more)

GPS III Space Segment Development

A Lockheed Martin-led team has submitted its proposal to design and build the U.S. Air Force's next-generation Global Positioning System Space Segment program, known as GPS Block III. This program will improve position, navigation, and timing services for the warfighter and civil users worldwide and provide advanced anti-jam capabilities yielding improved system security, accuracy and reliability.   The proposal builds on the team's record of providing progressively advanced spacecraft for the current GPS constellation: the team designed and built 21 Block IIR satellites for the Air Force and subsequently modernised eight of those spacecraft, designated Block IIR-M, to enhance operations...
