Final answer:
Slight differences between GPS and conventional NAVAID data can be considered acceptable because both systems provide reliable navigation information.
Step-by-step explanation:
Yes, slight differences between GPS and conventional NAVAID data can be considered acceptable. This is because GPS relies on a system of satellites and atomic clocks to calculate positions, while conventional NAVAID data is based on ground-based navigation aids like beacons and radio signals. Although there may be slight variations in the data obtained from these two systems, they are generally accurate and reliable for navigation purposes.
For example, GPS measurements are often spread out but still relatively close to the actual location, indicating a low precision but high accuracy measuring system. On the other hand, conventional NAVAID data may be more concentrated but far away from the target location, indicating a high precision but low accuracy measuring system.
In conclusion, while there may be slight differences between GPS and conventional NAVAID data, these differences are considered acceptable because both systems provide reliable navigation information.
