Applications and Properties

Example

Case Study 1: Two LORAN (Long Range Navigation) stations, AA and BB, are located 400 km400\text{ km} apart. A ship receives a navigational radio signal from station AA exactly 1000 microseconds1000\text{ microseconds} (1000μs1000 \mu\text{s}) before it receives the synchronized signal from station BB. Assuming radio signals travel at 300 m/μs300\text{ m/}\mu\text{s}, determine the equation of the hyperbolic path the ship lies on, placing the midpoint between the stations at the origin.
