SRD-500S recovery devices are installed at 600m intervals along the streamer. If a streamer is severed or becomes detached from the tow vessel and sinks, the recovery device automatically detonates at a water depth of 48m and releases compressed CO2 into a floatation bag. After the SRD bag inflates, the streamer floats with the SRD to surface for recovery. Concord SRD-500S 48m 600m 8 Years Partnerplast Powered From Streamer and Onboard Battery / Generator

Because the differential GPS corrections are

11 broadcast via Inmarsat geostationary satellites, the user needs no local reference stations or post-processing to get this exceptional accuracy. The worldwide coverage of the geostationary satellites delivers a consistent high level of accuracy virtually anywhere from 72 N to 72 S latitude. Manufacture C&C Technologies Inc Type C-NAV 2050M Tracking Channels PPS Output Yes Real time DGPS Accuracy Position (H) < 10 cm Real time DGPS Accuracy Position (V) < 15 cm Real time DGPS Accuracy of Velocity 0.01 m/s Corrections Star-Fire Network delivered via Inmarsat satellite system DGPS Veripos Ultra Description The VERIPOS Ultra service is a precise positioning service designed to deliver decimeter level position accuracy, globally. The service is based around Precise Point Positioning (PPP) a technique where all GPS system errors are removed or minimized by direct calculation, precise modelling or estimation. PPP consists of a single set of corrections to the GPS satellite orbits and clocks, allowing position accuracy to be maintained regardless of user location. Measurement precision is achieved by using both L1 and L2 carrier phase observations, along with C/A and P-Code measurements.
