GNSS GNSS RECEIVER WITH AN ON-BOARD CAPABILITY TO IMPLEMENT AN OPTIMAL ERROR CORRECTION MODE

摘要

The present invention relates to a GNSS positioning signal receiver in which a computer logic operation unit which selects a first operation mode for using all usable frequencies and a second operation mode for using the combination of all usable frequencies and usable correction data is included. This selection is based on a comparison with a precise reliability level of a correction value estimated or calculated with a quality index of a reception area. A plurality of correction types including a type using a local model and a type using a combination correction value are possible. In some embodiments, a plurality of local models are selected and/or combined to optimize the accuracy of the correction values.
