What type of error arises from inaccuracies in satellite orbit data?

The correct answer is ephemeris error. This type of error occurs due to inaccuracies in the satellite's orbit data, which can affect the precision of the satellite's positional information. The ephemeris data provides the expected position of the satellites in their orbits at given times. If this data is not accurate, the GPS receiver may calculate the user's position incorrectly, leading to significant location errors.

Understanding ephemeris error is crucial for applications relying on high-accuracy positioning information, as even small inaccuracies in satellite orbit can cascade into substantial positioning errors for users. Addressing this type of error often involves improving the tracking systems and algorithms used to compute satellite orbits or using updated ephemeris information to enhance overall accuracy in geographic data systems.
