"There's a tendency to think that maybe if we can just throw enough hardware at the AI problem, then evolution can take care of the rest. Certainly that's how God went about making us."

![]() Marooned on Neptune (the icy part that the planetary engineers had not remade into usable farmland), Bob Star and his companions seem lost. But are they?
How might this amazing device be constructed without a network of GPS satellites? Williamson was probably thinking about using intertial guidance systems to indicate position; I haven't read about anyone who had thought of providing a read-out of path.
The basic idea behind inertial guidance systems is simple. Take a set of gyroscopes and set them in a known direction; if left to float freely, they will continuously indicate true direction. Then, use accelerometers to determine motion. These systems have the advantage of not relying on outside signals (which could be jammed); however, they are prone to cumulative errors.
Gyroscopes have been used to indicate direction on ships since the early 1900's. Rocket scientist Robert Goddard theorized that they would be useful in rocketry. The first successful inertial guidance systems were used in V2 rockets in the mid-1940's by German scientists. Read more about inertial guidance systems.
