Modulus Launches Submersible GPS Receiver
Modulus Technology, based in Great Yarmouth, UK and part of the AAE Technologies Group, has recently introduced its new, submersible GPS receiver with integrated L1 + L2 antenna to the marine survey market.
The so-called MiniPod 101G provides streamer head and tail positioning, source positioning for 3D UHR seismic operations and according to Modulus, it is ideal for the positioning of subsea excavation vehicles, or towed sensors such as magnetometers, that operate in shallow waters.
The MiniPod 101G will survive immersion to 10 meters. It is 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 range should shortly be available and should include a MiniPod with AHRS sensor, the MiniPod 101A, and a version with the GPS and sensor combined for complete precision, the MiniPod 101GA.
