Hemisphere GNSS Eclipse P328 OEM Positioning Board

Today, Hemisphere GNSS has announced the Eclipse P328 in a line of low-power, high-precision, positioning OEM boards. The multi-frequency, multi-GNSS P328 is an all-signals receiver board that includes Hemisphere’s new hardware platform and integrates Atlas GNSS Global Corrections. Designed with this hardware platform, the overall cost, size, weight and power consumption of the P328 are reduced. It offers true scalability with centimetre-level accuracy in either single-frequency mode or full performance multi-frequency, multi-GNSS, Atlas-capable mode that supports fast RTK initialisation times over long distances. The 60mm x 100mm module with 24-pin and 16-pin headers is a drop-in upgrade for existing designs... (read more)

VRS Systems for Improved Efficiencies in Port Operations

Mariners were one of the first public groups to adopt GPS in its early days Ð nearly twenty years ago. The next leap forward in the acceptance and widespread use of GPS was Differential GPS (DGPS). DGPS was driven by demand from the offshore marine survey industry, which wanted reliable, round-the-clock, sub-metre accuracy. Accuracy being infectious, the marine survey industry adopted the centimetre-accurate Real Time Kinematic (RTK) GPS surveying that land surveyors had pioneered. The latest development in precision surveying accuracy and reliability is enhanced RTK using the Virtual Reference Station (VRS) system. This paper explains VRS application in the... (read more)

Marine Construction Receivers

Trimble has introduced two new Global Positioning System (GPS) receivers designed specifically for marine construction applications: the Trimble SPS361 and Trimble SPS461 GPS Heading Receivers. These dedicated marine receivers deliver both precise GPS heading together with Differential GPS (DGPS) or Real Time Kinematic (RTK) positioning.   The receivers are developed for a range of applications when used with Trimble HYDROpro marine software, including: the precise placement of structures such as piles, bridges, caissons, marinas, and coastal defenses; dredge head positioning; vessel positioning and tracking; and offshore rig positioning with anchor handling.   The Trimble SPS361 is an entry-level DGPS Heading...

GNSS Antenna for Accurate Maritime Applications

Topcon Positioning Systems (TPS, USA) has announced the MG-A8 antenna for navigation and precise positioning in marine applications. The antenna provides GNSS signal tracking while not being susceptible to signal jamming from other sources, such as Inmarsat communications. It  can be used in DGPS mode for metre-level navigation purposes but can also be used for RTK centimetre-level positioning in areas where there is a network of reference stations available to support this level of precision. With its RTK capabilities, the MG-A8 is suited for applications such as dredging in inland river channels and waterways, according to Tom Morris, TPS senior... (read more)

NavCom Teams with I.T.S. Corporation to Win U.S. Naval Oceanographic Office Contract

NavCom Technology, Inc. have teamed with I.T.S. Corporation (ITS) to win the award of a multi-year contract to provide the U. S. Navy, Naval Oceanographic Office (NAVOCEANO) with an integrated Real Time Kinematic (RTK) and Satellite Based Augmentation (SBAS) Global Positioning System (GPS) for inshore hydrographic and offshore oceanographic vessels. The award was made under the ITS’s General Services Administration’s (GSA) ANSWER contract. The initial task order under the GSA ANSWER contract is to deliver 13 systems with options for 16 additional systems in the years following. The basis of the solution is the StarFire Network, the first global satellite... (read more)

GNSS Improvements for Offshore Applications

Fugro Marinestar G4+ PPP-RTK Developments
Currently, there are four global navigation satellite systems (GNSS) available: GPS, Glonass, Beidou and Galileo. These satellites can be used directly, but accuracy is greatly improved when using orbit, clock and UPD correction signals. Fugro Satellite Positioning operates a worldwide network of more than 100 GNSS reference stations capable of tracking the GNSS. This network is used to calculate precise satellite orbit and clock corrections for all four constellations in real-time for hydrographic applications. The corrections are broadcast to the maritime users by geostationary L-band satellites providing worldwide coverage. This article describes recent developments and the resulting accuracy of specifically the...
