High Accuracy GPS Data

Blue Marble Geographics, USA, has presented during the 2011 Maine Municipal Technology Conference. Samuel Knight of Blue Marble presented a talk on High Accuracy GPS - Pitfalls of Post-Processing at the 3rd March conference held in Bangor, Maine. The conference was well-attended by municipality representatives from around the state and highlighted the dramatic technological changes currently underway while trying to predict the impact on government services. Knight, the director of Product Management for Blue Marble, focused on avoiding the variety of pit falls that a novice user can run into, which may significantly degrade of the quality of the GPS...

Hemisphere GPS Outback BaseLineHD

In response to farmers growing demand for increased accuracy at a more affordable price, Hemisphere GPS (KS, USA) has developed another option to subscription networks and high-priced base systems. Using high-definition, single-frequency RTK, Outback BaseLineHD provides the same accuracy as dual-frequency RTK but at a fraction of the cost. Used in combination with Outback S2 and Outback eDrive, BaseLineHD provides one inch pass-to-pass accuracy in an affordable hands-free GPS steering system. Outback BaseLineHD includes an integrated base station and a single rover unit. Multiple vehicles can be equipped with additional rover units all operating from a single base system. In...

Trimble GPS Pathfinder ProXRT

Trimble (CA, USA) has introduced the GPS Pathfinder ProXRT receiver, a flexible GNSS receiver for GIS data collection and mapping. The receiver combines a high- performance GPS receiver with Trimble H-Star technology, OmniSTAR correction capability, and optional GLONASS capability to provide various levels of positioning accuracies, from submetre to decimetre (10cm) accuracy. The ProXRT receiver is ideal for high-accuracy mapping, data collection, and asset management applications in industries such as water/wastewater, utilities, telecommunications, transportation as well as many others. In recent years, these industries have experienced the need for subfoot and decimeter level performance.   With Trimble's patented H-Star technology,... (read more)

Archer Longbow Handheld GPS

Juniper Systems and Surveylab have launched the Archer Longbow remote positioning GPS handheld. By combining a rugged computer, GPS receiver, 3D compass, digital camera and a laser rangefinder, the Longbow provides the user with an all-in-one mobile GIS data capture solution. The laser is available in 100m, 300m and 1,000m versions.   The user simply points the Archer Longbow at a target up to a kilometre away, pushes a button, and captures the target's GPS coordinate plus a picture of the target. It then produces a verifiable, geo-tagged digital image with crosshairs and other information superimposed on the image to... (read more)

Integrating GPS and SAR

Monitoring Coal-field Subsidence
Subsidence of the earth's surface caused by underground mining can be monitored using terrestrial land-survey methods. However, applying these is difficult in hilly terrain and densely forested or urbanised areas. Such difficulties can be overcome with a combination of spaceborne SAR and GPS. InSAR accuracy corresponds to GPS and lies, with 9mm variance, in less than 8% of SAR signal phase.<P> When a point on the earth's surface is subject to deformation such as subsidence, the distance, or slant range, between an orbiting SAR sensor and the point gradually changes over time. Slant range can be determined by measuring the... (read more)

Iranian Permanent GPS Network

Using GPS to Understand Earthquakes
Lying in one of the most tectonically active zones in the Alpine-Himalayan belt, Iran frequently suffers from heavy and disastrous earthquakes. To monitor surface displacement and measure velocity and strain fields, the National Cartographic Center of Iran (NCC) has established a network of one hundred GPS stations: the Iranian Permanent GPS Network for Geodynamics (IPGN). The authors introduce the design of the new geodetic network. Iran is situated between the Eurasian plate in the north and the Arabian plate in the south, with shortening rate of 2-2.5cm per year. Many earthquakes occur in this area, causing enormous loss of life... (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)
