Which system enhances GPS signal for improved location accuracy?

• A. WAAS
• B. NISAR
• C. LEO Satellites
• D. IR Sensors

Answer: (A)

The correct choice is WAAS, which stands for Wide Area Augmentation System. WAAS is specifically designed to improve the accuracy of GPS signals by correcting common sources of error, such as atmospheric delays and satellite orbit inaccuracies. It does this by using a network of ground reference stations that monitor GPS signals and calculate corrections. These corrections are then transmitted to geostationary satellites, which broadcast the corrected signals to users on the ground, enhancing the precision of their GPS locations significantly. WAAS is particularly beneficial for aviation and other applications where high precision is paramount. By augmenting the GPS system in this way, WAAS enables users to achieve location accuracy within a few meters, making it an essential tool for operations that rely on precise navigation. Other systems listed do not serve the same function as WAAS in improving GPS signal accuracy.
