Narrative:

During climb-out with a notam warning of GPS jamming in the area; we did receive an ads-B left icas message around the mid 20s. We complied with the checklist and a few moments later we received an ads-B right icas message. While running through that checklist we noticed the anp was 1.02. After we finished the checklist we were approaching our level-off so I waited to do any other investigation until the level off was complete. Just after level-off; the anp went back to .02 and the alerts were gone. We let control know and did write up the alerts in the maintenance log.

Title: Captain reported experiencing GPS jamming as was predicted by NOTAM.

Narrative: During climb-out with a Notam warning of GPS jamming in the area; we did receive an ADS-B L ICAS message around the mid 20s. We complied with the checklist and a few moments later we received an ADS-B R ICAS message. While running through that checklist we noticed the ANP was 1.02. After we finished the checklist we were approaching our level-off so I waited to do any other investigation until the level off was complete. Just after level-off; the ANP went back to .02 and the alerts were gone. We let Control know and did write up the alerts in the maintenance log.
