Narrative:
I had forgotten my GPS navigation cards after bringing them home to update; but had an ipad for current charts. I was heading south along the coast. I was watching the coastline for distance and clearance from the sna [charlie] airspace. [Because of] the haze around me I realized I felt too close to the shore. The ipad said it had lost the GPS signal. I immediately descended and turned away from shore fearing I was inside the [charlie] airspace. I switched my radio to the guard frequency (121.5) and listened; but did not broadcast. I heard nothing. I believe the haze contributed since I was focusing on the immediate space around me and watching for traffic versus head in cockpit watching the ipad. I continued south for the flight and eventually turned to crq. On the return I made very sure I had plenty of space to land. I almost went all the way to catalina (sxc) and then turned towards toa. I landed without incident. I have two GPS units onboard and the ipad is the backup. I learned to only update one GPS at a time and I added an item to my checklist to confirm I have at least one operational GPS. I am not sure I violated the sna [charlie] airspace as I had no DME and did not trust the ipad but felt I should file this report in case. The distance and radials are approximate.
