POSITIONING APPARATUS, COMPUTER READABLE MEDIUM, AND POSITIONING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18277076 titled 'POSITIONING APPARATUS, COMPUTER READABLE MEDIUM, AND POSITIONING METHOD

Simplified Explanation

The patent application describes a positioning apparatus that corrects pseudo ranges and carrier phase integrated values of ranging signals, performs positioning using observation equations, and executes a filter operation for accurate positioning.

• Detects pseudo ranges and carrier phase integrated values from ranging signals (L1C/A) with augmentation information provided.
• Detects pseudo ranges and carrier phase integrated values from ranging signals (B1C) without augmentation information.
• Acquires correction data for the ranging signals generated from the augmentation information.
• Corrects the pseudo ranges and carrier phase integrated values of the ranging signals (L1C/A) with the correction data.
• Generates a first observation equation using the corrected values of the ranging signals (L1C/A).
• Generates a second observation equation using time difference values between the pseudo ranges and carrier phase integrated values of the ranging signals (B1C).
• Performs positioning by executing a filter operation using the observation equations.
