<Tab/>For years our ancestors having been relying on the stars to cordinate their direction and position when traveling. Some of the greatest explorers of our time, Leif Ericson, Marco Polo, Prince Henry, Christopher Columbus, Amerigo Vespucci, and Vasco da Gama all had to rely on the stars to calculate their positions or the direction they were traveling using two important principles:

…showed last 75 words of 612 total…amp;gt;Single-channel GPS have 1 radio receiver, and they must step "sequentailly" through all possible satellites. This takes the longest time and degrades the acccuracy. Parallel-channel units must have 12 receivers, each dedicated to 1 satellite signal, so strong locks on the satellites can be made.
<Tab/>Today, we use Parallel-channel units so that in difficult situations their ability to lock onto satellite signals through heavy trees or skyscrpapers can still be maintained.
