Hemisphere GPS Vector GPS Compass

At the Oceanology International exhibition and conference in London, UK, Hemisphere GPS has announced the introduction of its Vector V103 GPS compass and Vector V113 GPS compass, both designed for professional, commercial marine and machine control applications. Powered by Hemisphere GPS’ Crescent Vector II technology, the new Vector V103 and V113 provide precise heading and positioning performance including heave, pitch, and roll with the option of either NMEA 0183 or NMEA 2000 communications. The rugged enclosure gives these Vector models the advantage of working reliably in such harsh environments as side-scan survey, multi and single beam surveys, dredging, general navigation...

GPS Innovation Alliance to Support GPS Importance

Citing the ever-increasing importance of the Global Positioning System (GPS) to the global economy and infrastructure, a group of GPS advocates have announced the formation of the GPS Innovation Alliance, an organisation dedicated to furthering GPS innovation, creativity and entrepreneurship. Members of the Alliance come from a wide variety of fields and businesses reliant on GPS. These include manufacturing, aviation, agriculture, construction, transportation, first responders and surveying and mapping. Other members include organisations representing consumers who depend on GPS for boating and other outdoor activities, and in their automobiles, smartphones and tablets. Headquartered in Washington, D.C., the GPS Innovation Alliance... (read more)

AHRs with Integrated GPS

The MTi-G is a MEMS IMU with integrated GPS. It contains an internal ultra low-power Attitude and Heading Reference System (AHRS) processor running a real-time Xsens Kalman filter. Key benefit of the compact MTi-G sensor is that it provides accurate horizontal and vertical position, velocity and orientation estimates.   As the MTi-G accomplishes this task with a high update rate and fidelity, it is an excellent measurement unit for navigation and control of marine vehicles and other autonomous or unmanned objects. Also available from Xsens is a Development Kit enabling easy integration of the MTi-G in any system or (OEM)... (read more)

New GPS Satellite Operational

The fourth in a series of eight modernized Global Positioning System (GPS) satellites that will deliver new capabilities to military and civilian users has been declared fully operational.   Launched from Cape Canaveral October 17, the satellite was given the all clear after an on-orbit checkout by a combined U.S. Air Force/Lockheed Martin team. Read more   The satellite joins three IIR-M satellites and 12 other operational Block IIR satellites within the current 28-spacecraft constellation. The fifth GPS IIR-M satellite is scheduled for launch on 20th December 20, 2007 from Cape Canaveral.     (read more)

Retiring GPS Base Stations

Since GPS found its way into positioning, differential processing has beentheway to high precision. Technological advances and large-scale international collaboration have now made it possible to get sub-decimetre accuracy (95%, 3D) without reference stations. Terratec is aiming to be the technology leader in this new way of positioning.<P> The use of reference station services, or even ones own reference stations, has been part of the game for most hydrographic surveyors for almost two decades, and for some applications it will still be the preferred solution. Even though GPS satellite signals have remained more or less unchanged since the system was... (read more)

GPS Compass Board

Hemisphere GPS' LV100 is a complete GPS compass and positioning assembly utilising a unique design featuring a single carrier board with integrated GPS antennas, designed for easy integration by OEM customers. The LV100 integrates two GPS antennas, an NMEA 2000 communication processor, a single axis gyro, a tilt sensor, and a power supply into a single system. The dual integrated antennas provide both heading and position data, and the gyro and tilt sensor improve system performance and provide backup heading information, if the GPS-based heading is ever lost.  The Crescent technology provides highly accurate code phase management and outstanding multipath...

GPS/Acoustic Seafloor Observation

Crustal Movement Around Japan
GPS/Acoustic Seafloor geodetic observation technique has made notable progress over recent years. Positional precision better than several centimetres has been attained through tremendous efforts to improve accuracy in both software and hardware. Some remarkable results have been obtained: intraplate crustal velocity off the Pacific coast of NE Japan caused by subduction, and co-seismic displacement associated with an earthquake in 2005 off Miyagi Prefecture. BackgroundThe idea for GPS/Acoustic combination technique to measure seafloor crustal movement dates back to early work done by scientists at the Scripps Institution of Oceanography in America. They started geodetic observations using this technique on the Juan... (read more)

Galileo Interoperable with GPS

ESA’s first two Galileo navigation satellites in space have achieved their latest milestone, transmitting dummy signals in a modulation scheme designed to allow full interoperability with the US GPS once operational services start. An advanced modulation technique offers robust protection against signal interference and the misleading signal reflections known as ‘multipath’. The first two Galileo satellites were launched from Europe’s Spaceport in French Guiana into medium orbits on 21 October 2011, and since then have been progressively put through their paces in a series of tests. These satellites are serving to validate the Galileo system design as well as being... (read more)

Precision GPS Antennas

Hemisphere GPS' A52 and A21 are two new antennas adding precision, reliability, and value to the Crescent and Eclipse GPS technology. A52 is a multi-GNSS (GPS L1/L2/L5, GLONASS L1/L2, Beidou, SBAS, OmniSTAR, and Galileo E1/E5a and b) precision antenna that is ideal for various applications including post-processed geodetic surveys, RTK positioning and navigation, precise guidance, and machine control. A52 can be used in challenging environments (such as near buildings and foliage) as it has superior multipath mitigation, a stable phase center, and strong SNRs even at low elevations.   A21, already used for aerial application guidance and flow control but...
