GPS Signal Jammers for sale craigslist - jamming wifi legal forms

Brazilian geoscience services company OceanPact Geociências has chosen deep-water positioning technology from Sonardyne Brasil Ltda. to support its geophysical, geotechnical and environmental research operations across the region. Ranger 2 ultra-short baseline (USBL) systems have been installed on board OceanPact’s research vessel Seward Johnson and RSV Austral Abrolhos to precisely track the location of underwater equipment and sensor packages deployed from the ships, including seabed corers, towed sensors and data loggers. Both vessels are currently on hire to Brazilian oil major Petrobras. Ranger 2 USBL is a popular choice for conducting research at sea as operations can start as soon as a vessel arrives on location. This helps maximise valuable ship time. It has the capability to track multiple underwater targets simultaneously to beyond 11 kilometers, works in shallow or deep water and is able to remotely configure and communicate with compatible instruments. This operational flexibility was a key factor in OceanPact’s investment decision. “This order from OceanPact further embeds Ranger 2’s reputation in the region. For those wanting accuracy and versatility, it’s proven itself time and again while also meeting the toughest specifications from oil and gas, science and survey companies,” Andre Moura, sales and applications manager at Sonardyne Brasil Ltda.
