Magellan® Professional Announces the ProFlex™ 500 Marine for Precise Positioning and Coastal Surveying Nantes, November 3, 2009 – Magellan Professional today announced the availability of the ProFlex 500 Marine, a powerful GNSS receiver for offshore and onshore positioning and surveying. Available in single- and dual-frequency versions, ProFlex 500 Marine delivers real-time precision ranging from the submeter to centimeter level, and is compatible with virtually all marine receivers, including Magellan’s industry-leading Aquarius and Sagitta receivers and third-party receivers.

ProFlex 500 Marine is the ideal solution for companies looking for a single GNSS receiver to perform multiple offshore and onshore applications. Its flexibility and high performance are highly beneficial to hydrography services, dredgers and other demanding marine RTK operations.

Vessel Positioning and Marine Surveying

Embedded BLADEâ„¢ technology applies multiple GNSS constellations (GPS, GLONASS, SBAS) to deliver fast real-time centimeter-level precision enabling users to work more accurately and economically. Designed for shipboard use, the ProFlex 500 is made to withstand harsh environments. Its high-impact strength aluminum housing resists harsh conditions, including salt mist, 100 percent condensing humidity, shock and vibration. The floating power input, the earth terminal and the optically isolated input/output signals ensure that your investment is reliable and safe in all conditions. Additionally the fast output rate, up to 20Hz, makes ProFlex 500 the ideal receiver for many types of demanding kinematic applications. The receiver offers long-range RTK capability, the latest Magellan Professional U-Link radios for dependable UHF communications, and dedicated mounting parts for easy shipboard installation.

On Shore Survey

Because the ProFlex 500 is easily adaptable to most any positioning application, including base station or rover, it is particularly valuable for dredging companies that perform coast and spoil surveying in addition to dredge positioning. Ashore the ProFlex 500 is highly versatile as either a rover or base station. Magellan provides a backpack kit to make rover surveying with the ProFlex 500 a snap. With its instant real-time multi-data streaming capability, the ProFlex500 as a base station offers easy access to RTK corrections for real-time centimeter accurate survey and mapping. Its Internet connectivity provides NTRIP and Direct IP capabilities enabling users to build their own DGPS and/or RTK corrections server without any additional software or equipment, which can be particularly convenient on a construction site without an available RTN correction network.

BLADE Technology Inside

The ProFlex 500 uses Magellan Professional’s BLADE Technology, which introduces a unique patented method to use multiple GNSS constellations for high-accuracy positioning. BLADE also accounts for the GLONASS receiver biases in reference stations, allowing the user to optimally use the GLONASS signals from any manufacturer’s receiver. BLADE even allows the receiver to benefit from GLONASS satellites in the absence of GLONASS correction data by properly weighting the uncorrected measurements.
