Question

In a GPS system, if one of the receivers is in relative motion with respect to the other receiver, having been mounted either on a vehicle, ship, or aircraft, it is called:

• A. kinematic GPS
• B. MDGPS
• C. DGPS
• D. Absolute GPS

Hint:

Kinematic GPS = 1 fixed + 1 moving receiver → used for precision in motion.

Answer 1

The Correct Option is A

In the context of a GPS system, different terminologies describe specific configurations or functionalities based on the application or setup that is being utilized. Let's clarify what each of these terms means and identify which one fits the given scenario.

• Kinematic GPS: This term refers to a system where at least one of the GPS receivers is moving. It is typically used in situations where the receiver is mounted on a vehicle, ship, or aircraft that is in motion, allowing for real-time tracking and navigation.
• MDGPS: Stands for Marine Differential GPS. It is specifically used for marine navigation to improve position accuracy.
• DGPS: Stands for Differential GPS. This system uses a network of fixed ground-based reference stations to broadcast the difference between the positions indicated by the GPS satellite system and known fixed positions.
• Absolute GPS: Refers to the standard GPS method that provides an absolute position (latitude, longitude, and altitude) based solely on satellite data.

Based on these definitions, if one of the receivers in the GPS system is in relative motion with respect to the other receiver, mounted on a vehicle, ship, or aircraft, it is called kinematic GPS.
