Magellan DG14 RTK GPS Board

The DG14 RTK offers high-precision in a low-cost GNSS unit. The DG14 RTK from Magellan is a sub-meter GNSS (GPS + SBAS) and Beacon receiver. DG14 RTK was developed to meet the needs of demanding high-precision applications for machine control, agriculture, aviation, military, unmanned aerial vehicles (UAVs), robotics, marine survey and navigation. DG14 RTK customers can choose from a fixed centimeter solution or a “flying RTK” decimeter solution. Because it offers an optimized mix of speed and accuracy, the decimeter mode makes DG14 RTK the perfect solution for customers who need decimeter accuracy but don’t want to spend the typical...

ALIGN Firmware for Two Models

NovAtel (Canada) has introduced its enhanced ALIGN solution, as part of the company's new 6.100 firmware release. The solution is available in two models: ALIGN Heading and ALIGN Relative Positioning. The two ALIGN models facilitate system installation with plug-and-play configuration and offer the flexibility to design either GNSS attitude or relative positioning solutions. ALIGN Heading generates high-precision 2D vehicle attitude (heading and pitch) between two antennas and can be extended to offer 3D attitude (heading, roll and pitch) with a third receiver. ALIGN Relative Positioning offers accurate relative positioning between two or more moving platforms for high precision monitoring and... (read more)

Marine Motion Sensor

Kongsberg Maritimes has introduced a new member in its family of Motion Monitoring Units at Ocean Business 2015. The MRU 5+ MK-II is part of a range of MRUs for diverse marine applications including: motion compensation of multi-beam echo sounders, high speed craft motion control and damping systems, heave compensation of offshore cranes, dynamic positioning, hydro acoustic positioning, ship motion monitoring, ocean wave measurements and antenna motion compensation and stabilisation. The MRU 5+ MK-II uses a new sensing element (Coriolis force resonator) in the new design of integrated MEMS gyros. With less than 0.002° angle noise, and Angle Random Walk... (read more)

Sonardyne Motion Sensor Technology

Sonardyne International has launched a new marine Attitude Heading and Reference System (AHRS): Lodestar. Lodestar has been developed to overcome the problems associated with conventional sensor platforms. The Lodestar AHRS is a natural extension of the Sonardyne product range and has been developed for seamless integration with the company’s widely used LBL (Long BaseLine) and USBL (Ultra-Short BaseLine) acoustic positioning systems. It will also be welcomed by users with any requirement for motion compensation to support operations in any sea conditions. These are likely to include platform stabilisation, dynamic positioning, buoy monitoring, subsea construction and towfish and ROV/AUV operations. Available... (read more)

North-seeking Gyrocompass

OceanTools has launched their MircoFOG north-seeking fibre-optic gyrocompass. MicroFOG delivers a wide range of parameters including heading, pitch, roll, rate information in three axes, accelerations and, shortly will include heave measurements.   The 3000m standard depth rated unit measures just 210mm in diameter and 360mm ling. The first production run of five units have already been sold with the US-based distributor SES.   (read more)

RTK Tide Basics

One of the fastest emerging trends in hydrographic surveying is the use of the vertical component of RTK GPS to determine real-time water level corrections. There are currently several district offices of the US Army Corps of Engineers using this technique in place of conventional tide measurements.The main purpose of this article is to explain some of the basics behind the technique (without getting overly technical) and to point out some of the benefits and drawbacks to the method. The Basics Looking at Figure 1, let’s define the following terms: For simplicity, I am ignoring the heave-pitch-roll of the vessel... (read more)

Stand 51 for New DMS-500 Range

A new addition to the Teledyne TSS range of DMS motion sensors is being launched at the Ocean Business exhibition, Stand S1. The DMS-500 range is being developed specifically to meet the needs of users who require a high-end motion sensor with Ethernet connectivity, but do not require the subsea-rated housings that typify Teledyne TSS products.     The result will be a complete range of conservatively-priced sensors that incorporate a number of advanced and innovative features for applications such as Dynamic Positioning (DP), wave height monitoring and structural stress monitoring. The versatile design means that the range will be... (read more)

Young Marine Scientists' Day: Call for Abstracts

During the 14th edition of the VLIZ Young Marine Scientists' Day, which is to be held on 7 March 2014 in Bruges, Belgium, the diversity, quality and relevance of marine and coastal sciences in Flanders is to be highlighted. The organisers challenge all marine and coastal scientists to prepare a short abstract presenting their research in a clear, concise and attractive way. The abstract should be of maximal 500 words and submitted by 16 December 2013. Twenty abstracts will be selected for a plenary session of short pitch presentations. The other participants will be able to present their work in... (read more)
