Claim 17:
18. A system comprising:
a positioning engine configured to determine a position of a GNSS receiver using a set of satellite signals measured by the GNSS receiver; wherein the positioning engine uses an integer nature of carrier phase ambiguities of the satellite signals to determine the position; wherein the positioning engine receives corrections information generated by a corrections generator operating on a computing system remote from a computing system operating the positioning engine; wherein the corrections information comprises corrections data, an integrity flag when an integrity issue is detected, and a probability of a predetermined event; wherein the integrity flag comprises a satellite flag when the integrity issue is associated with a satellite effect and an atmospheric flag when the integrity issue is associated with an atmospheric effect; wherein the set of satellite signals are corrected using the corrections data; wherein when the satellite flag is issued, the positioning engine uses atmospheric corrections of the corrections data to partially correct the set of satellite signals; wherein when the atmospheric flag is issued, the positioning engine uses satellite corrections of the corrections data to partially correct the set of satellite signals; wherein an integrity of the position depends on the probability of the predetermined event; wherein an accuracy of the position depends on an accuracy of the corrections data.
