PBX Systems LLC introduces PosNet, a GPS module for positioning seismic streamers. PosNet is a lightweight, rugged and cost effective alternative to existing products in the market place today.
PosNet’s fully integrated packaging encloses both the GPS and RF antennas within a protective housing to help make installation both quick and easy.
PosNet’s light weight ( 8 lbs ) and small size ( 4.5 inch diameter and 20 inch length ) provide greater flexibility in module placement. When PosNet is powered up, the unit will self configure.
*** No operator intervention is required beyond initially assigning a unit ID. ***
