Today’s professional GNSS receivers can be used for a wide range of applications including surveying, agriculture, forestry, automotive positioning, and defense. As satellite navigation is used increasingly, the number of applications will become greater in the future. Professional applications typically require a high level of precision and reliability.
Modern systems often benefit from multi-frequency or multi-antenna usage. By utilizing navigation signals broadcasted on different frequencies it is possible to minimize the erroneous effect of the ionosphere, resulting in a more accurate positioning performance. Using multiple antennas for the reception of the same signal makes it possible to measure inclination. of an airplane or an object like an oil platform.
