Aviation servicef1
| The performance specifications included in this table address only signal-in-space contributions. | ||||
| A range is given for service availability for approach procedure. The bottom of the range shall correspond to the availability expected for the GPS L1-only service. The top of the range shall be available for users equipped with a dual frequency GPS L1-L5 receiver or a combined GPS/Galileo dual-frequency receiver. | ||||
| ‘Land masses of an area’ means any land territory, including islands, in the FIR of that area except for the Cat I service for which coverage of Azores, Madeira and Canary Islands are excluded. | ||||
| Until sufficient Galileo performance is demonstrated, APV-I service level is accepted. | ||||
