What are the disadvantages of the global positioning system?

Answer 1

Cost

• Purchasing a GPS based on price can be a major disadvantage. If you purchase a "bargain GPS," you will get what you pay for, and features such as traffic and up-to-date maps could be lacking.

Reception

• GPS devices are limited by having clear access to the satellites that provide the tracking. In locations with tall buildings or sparse coverage, reception can be poor.

Directions

• Turn-by-turn directions are not available on every type of GPS device. Some will give very little advanced notice before an upcoming turn.

Accuracy

• Maps on GPS devices are not updated in real time for all models. This means that it is possible a GPS device will direct you onto a road that is closed or no longer exists. It could also miss new roads and businesses.

Battery Life

• GPS units that are not plugged into a power source, and rely on batteries, which can drain quickly. This can increase the cost of owning a GPS unit significantly

Answer 2

A global positioning system may give out someone's position and that will affect his security. Geotagging of photos slightly increases the chances of a child being kidnapped.
