GPS Pirates

Modern-day piracy in Somalia
The Gulf of Aden is currently one of the world's most dangerous shipping routes. Pirates originating from Somalia, or rather that part of the country called Puntland, launch frequent attacks on commercial vessels bound for the Suez Canal or the Indian Ocean. Pirates - the word sounds medieval, and their vessels sometimes also resemble classic pirate vessels, including skull-and-crossbones flag. However, don?t be misled; these modern-day pirates use state-of-the-art equipment. Not only do they boast an impressive array of armaments, they also use the latest versions of GNSS, GIS and telecommunication equipment. Vessels passing the Bab al Mandeb between the... (read more)

Dual GPS

OxTS is releasing a new dual antenna version of the Inertial+ navigation system at this year's Intergeo exhibition. The new Inertial+2 provides improved heading accuracy for better performances in airborne survey and mapping applications.         Being compatible with most GPS receivers on the market, the Inertial+ is very easy to integrate in to a current GPS only solution. Adding the Inertial+ to a GPS receiver will not only provide reliable, continuous position data even during GPS signals blockage but also output measurements like roll, pitch and heading with high accuracy in real-time. Using two GPS receivers in the... (read more)

Geodetic GPS

Is the moment coming when our GPS product survey will have to be renamed? Any new title should reflect the existence and use of GLONASS receivers, combined GLONASS/GPS receivers and Galileo receivers. But the results of this year’s product survey do not yet give reason for such a step. Healthy and stable competition has emerged over the years among manufacturers of receivers. Satellite signals coming to us from space, GPS next to GLONASS, and in the future Galileo, each have their own characteristics. These make the signals in part complementary to each other. From a technical point of view this... (read more)

GPS Goggle

The Zeal Optics Transcend GPS Goggle enables skiers to monitor their speed and altitude, as well as the time and vertical speed, using the GPS Goggle. The various data are visible on a head-up display. The stats can be downloaded on your computer with a Google Map overlay to review performance. The rechangeable lithion-ion battery allows 7 hours run time. The goggle is PC and Mac compatible and includes European and American adapters and the software allows Imperial and metric units.The goggle itself is polarised and reduces 99% of the glare. The lens is in-molded and anti-fog treated. The frame... (read more)

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 US-based 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 are drawn from a wide variety of fields and businesses reliant on GPS. These include manufacturing, aviation, agriculture, construction, transportation, first responders and surveying and mapping. Still others are 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., USA, the... (read more)

Hemisphere GPS Eclipse Dual-Frequency GPS Receiver

Hemisphere GPS (Canada) has introduced its enhanced Eclipse dual-frequency GPS receiver. The Eclipse receiver now supports USB communication and enables data logging to standard external USB flash drives. It also now utilises an expanded number of standard RTK (Real-Time Kinematic) message formats, such as RTCM v3, CMR, and CMR+, making the Eclipse receiver compatible with CORS (Continuously Operating Reference Stations) and other RTK base station networks. The Eclipse receiver also includes the updated library from OmniSTAR, delivering improved acquisition time and performance.   An affordable dual-frequency solution, the Eclipse receiver delivers reliable centimetre-level accuracy by reducing code measurement noise and...

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)

GPS L-Band Threatened

The L-band, in which the GPS/GNSS L-1 signal also resides, might soon be overcrowded in several US densely populated areas. LightSquared (a Mobile-satellite service operater (MSS) and Ancillary Terrestrial Component (ATC) license holder) is seeking a reallocation of its L-band from a space service to primarily a terrestrial wireless service. Lightsquared would like to provide primarily voice and data broadband services on the L-band frequencies they currently hold a license for. This change in usage of the bandwidth together with a densely populated powerful (1500 W) transmitter network could mean that the GPS/GNSS L-1 signals are negatively influenced. This could...

Japanese GPS Reference Stations

Topcon has been selected by the Geographical Survey Institute (GSI), an affiliate of the Japanese Ministry of Land, Infrastructure, Transport and Tourism (MLIT), to supply GPS reference stations. The company will supply 360 GPS receivers as well as new software and database system for the GPS Earth Observation Network System (GEONET) operated by GSI. It is expected the new systems will be in operation by the end of March 2010.     In 1992, GSI initiated the introduction of Global Positioning System (GPS) Continuously Operating Reference Station (CORS) known as GEONET. As of March 2009, nationwide 1,236 stations are in... (read more)
