Abstract
A method for evaluating satellite positioning quality and a satellite receiver are disclosed. Satellite information is obtained from one or more satellites of the set of satellites. The satellite information includes an observed value of a parameter of each of the one or more satellites. An estimated value of each observed value is determined based on the satellite information. A set of residual values between the estimated values and the observed values is obtained. A positioning quality associated with the set of satellites is determined based on the set of residual values.
Claims20
A method for evaluating satellite positioning quality associated with a set of satellites, comprising steps of:
- obtaining, from one or more satellites of the set of satellites, satellite information including an observed value of a parameter of each of the one or more satellites;
- determining an estimated value of each observed value based on the satellite information;
- obtaining a set of residual values between the estimated values and the observed values;
- and
- determining a positioning quality associated with the set of satellites based on the set of residual values.
A satellite receiver for evaluating a positioning quality associated with a set of satellites comprising:
- an acquisition module configured for obtaining, from one or more satellites of the set of satellites, satellite information including an observed value of a parameter of each of the one or more satellites;
- an estimated value calculating module configured for determining an estimated value of each observed value based on the satellite information;
- and
- a residual value calculating module configured for obtaining a set of residual values between the estimated values and the observed values and for determining a positioning quality associated with the set of satellites based on the set of residual values.
