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...

GPS/GLONASS RTK Receiver Module

The Ashtech MB100 GNSS board has been developed for applications when power consumption, size and dependable performances such as raw data quality, real-time positioning (SBAS up to RTK) or GNSS heading + pitch/roll determination are critical. The MB100 is designed to address L1 GPS+SBAS applications - including heading + pitch/roll determination. Ashtech’s Z-Blade Technology and dual-frequency GPS configuration offerlong-range RTK performance, while single-frequency GPS + GLONASS configuration provides more satellites in view for demanding environments. Embedded Z-Blade GNSS centric technology uses all available GNSS signals equally, without any constellation preference, to deliver fast and stable solutions. The MB100 works as... (read more)

Hemisphere GPS Revenue Increases 35%

Hemisphere GPS has reported their financial results for the fourth quarter and year ended 31st December 2008. The company achieved a 35% increase in revenues to a record of USD72.7 million, versus USD53.7 million in 2007. 2008 growth was driven by strong market fundamentals in agriculture during the year including high farm incomes. Revenues in the Ground Agriculture business grew 34% for the year, while the Air Agriculture business grew 31%.     Strong grain commodity prices lead to record net farm income in the United States in 2007, and similarly in other countries, which in turn drove stronger sales...

GPS-powered Personal Location Tag

Fastrax Ltd and Alltigo Inc. have integrated a Fastrax iTrax03 GPS receiver into the Alltigo Location Tag LT100, a small, location-aware electronic device that enables the global positioning of a person, vehicle or any other kind of mobile asset with an accuracy of a few meters. The LT100 communicates its location and receives commands over a GSM/GPRS mobile phone network via TCP/IP or SMS. The Location Tag LT100 does not have a keypad or display of its own; instead, the device is controlled with commands issued through a cell phone or computer. (read more)

GPS for Global Tidal Measurements

Recent data analysis heralds applications for hydrography
Hydrographers require accurate three-dimensional positions of the survey vessel and typically use differing methods for resolving the horizontal and vertical components. GNSS, such as the Navstar Global Positioning System (GPS), have become the dominant horizontal positioning system for hydrographic operations, whereas tidal estimation is the foremost method used in determining vertical positioning. The tidal estimation method integrates a water level measurement at a remote location with a predicted propagation of the tidal wave, to establish a sea surface level at the desired location. This paper investigates a new method using GNSS as an aid in improving these water level estimates... (read more)

High-performance Modular GPS Receiver

Trimble introduced the Trimble DSM 232 Receiver, a high-performance GPS receiver capable of sub-meter, decimeter and centimeter accuracy for both harbor and waterway applications and for system integrators. The modular receiver is designed for dynamic, real-time positioning operations on water, such as waterway dredging where it is integrated as the positioning sensor component. The GPS receiver is easily upgraded to increase performance as positioning requirements change. For waterway and harbor applications, the Trimble DSM 232 GPS receiver allows operators to save time and reduce operational costs. Setup time is greatly reduced as well as cost of ownership because the operator... (read more)
