Abstract
Disclosed is a system for determining a protection level. The system includes a receiver configured to receive an error augmentation for a satellite orbit and clock error, an error augmentation for an ionospheric error, an error augmentation for noise and multi-path between a receiver and a satellite, and an error augmentation for a tropospheric error, a first calculator configured to calculate a first adjustment coefficient to be applied to the error augmentation for the satellite orbit and clock error and the error augmentation for the ionospheric error, and a second calculator configured to calculate a protection level by applying the first adjustment coefficient.

A system for determining a protection level, the system comprising:
- a receiver configured to receive an error augmentation for a satellite orbit and clock error, an error augmentation for an ionospheric error, an error augmentation for noise and multi-path between a receiver and a satellite, and an error augmentation for a tropospheric error;
- a first calculator configured to calculate a first adjustment coefficient to be applied to the error augmentation for the satellite orbit and clock error and the error augmentation for the ionospheric error;
- and
- a second calculator configured to apply the first adjustment coefficient to the error augmentation for the satellite orbit and clock error and the error augmentation for the ionospheric error and calculate a protection level using the error augmentation for the noise and multi-path between the receiver and the satellite and the error augmentation for the tropospheric error;
- wherein the second calculator applies, to the calculated protection level, a second adjustment coefficient calculated from an integrity probability requirement allocated to a user.
A method of determining a protection level, the method comprising:
