Modulus Technology has recently introduced its new, robust submersible GPS receiver with integrated L1 + L2 antenna to the marine survey market. Named the MiniPod 101G, this lightweight yet rugged product provides streamer head and tail positioning, source positioning for 3D UHR seismic operations and is ideal for the positioning of subsea excavation vehicles, or towed sensors such as magnetometers, that operate in shallow waters.
Though designed for operation on a floating catamaran, hydrophone or trencher etc., the MiniPod 101G will survive immersion to 10m. It is only 170mm in length and 115mm diameter, and is externally powered by default but can be provided with internal power fail back-up as an option. Internal and external shock mounts protect the L1 + L2 band GPS receiver that has both wired and wireless applications. Further developments in this successful range will shortly be available. www.modulustechnology.com
