Tech: Crystal Gravfield Trap (CGT)

Crystal Gravfield Trap
Prerequisites: Sensor Theory, Active Sensors.
Research Cost: Pending
Description
A Crystal Gravfield Trap (CGT) was a rare and expensive type of sensor that used a synthetic crystal grid to detect and identify fluctuations in the local gravity field. They could be blocked by the presence of mass, not being able to detect a ship on the far side of a planet due to its mass.
CGTs were the only sensor that could reliably detect a ship with an active cloaking device. 
Game Notes
Allows Crystal Gravfield Trap Starship Component to be added to Starship Designs.
