GPS reception is available around the globe.?You will need to have a clear view of the skies so the receiver can triangulate at least three satellites.

An office window works well, but you may have problems receiving signals in the inner area of buildings. In general, metal and masonry block GPS signals, while glass, wood, or plastic does not.

Under specific conditions, GPS will not provide the time. For instance, the 1,542 MHz GPS signal does not penetrate buildings, which makes it difficult to receive signals indoors away from windows. Also the signal can be critically weakened by heavy foliage and interfered with by other sources such as poorly maintained television broadcasting equipment.

GPS receivers integrate a radio and a navigation computer and can receive the faint, twenty-watt signals coming from the satellites. The computer uses these signals to calculate the distance between the satellites and the receiver. With this information, the computer can further calculate the position and velocity of the receiver.

The number of satellites visible to a receiver constantly varies between four and eleven according to time and location. Each satellite broadcasts a number of unique spread-spectrum codes, but only one, the Coarse Acquisition (C/A) code, is easily accessible for civilian use.

On the ground all GPS receivers have an almanac programmed into their computers that tells them where in the sky each satellite is, moment by moment.

You may also purchase accessories, including mounting units from Beagle Software. The only other requirement is a functioning Windows PC with an available serial (COM) port.
