Conversion device and computer readable medium
First Claim
1. A conversion device comprising:
- computation processing circuitry configured to acquire a plurality of types of positioning correction information used for correcting a positioning error resulting from a satellite that transmits positioning information and a positioning error resulting from a propagation path of the positioning information, approximate position being a positioning result, and a satellite position and a satellite velocity of the satellite that transmits the positioning information based on which the approximate position is calculated, the positioning correction information being defined for each error source in positioning of a mobile body and being included in a state amount message for positioning reinforcement, and based on the plurality of types of positioning correction information, the approximate position, the satellite position, and the satellite velocity of the satellite that have been acquired, generate a plurality of types of element data which are elements used for generating a plurality of types of positioning correction information which are different from the types of positioning correction information included in the state amount message, by computation; and
conversion calculation circuitry configured to combine the plurality of types of element data generated by the computation processing circuitry, to generate a plurality of types of positioning correction information indicating at least one of an observation amount used for positioning and a correction amount of the observation amount, by computation, as the plurality of types of positioning correction information which are different from the types of positioning correction information included in the state amount message.

Abstract
A mechanism converts positioning correction information included in an SSR message as defined by “RTCM STANDARD 10403.2” to positioning correction information conforming to “RTCM 10402.3”. A conversion device includes a computation processing section that acquires a plurality of types of positioning correction information conforming to “RTCM STANDARD 10403.2”, an approximate position being a positioning result, and a satellite position of a satellite that transmits positioning information based on which the approximate position is calculated, and based on the types of positioning correction information, the approximate position, and the satellite position that have been acquired, generates pieces of element data, such as CLR and ORB, which are elements used for generating the types of positioning correction information conforming to “RTCM 10402.3”, by computation, and a conversion calculation section that generates the types of positioning correction information conforming to “RTCM 10402.3”, based on the pieces of element data.
