My A77 would normally get a fix fairly quickly, now it no longer responds.
1 minute timeout setting was sufficient, but I altered it to 30 min, left the camera out in the open for 20 min, still no fix.

GPS settings are correct:
GPS On/Off = On
GPS Auto Time Corr = On
Use GPS Assist Data = On
Valid period 2018-05-08 to 2018-06-07

I've concluded that the GPS unit has failed, has anyone else had this issue or can suggest anything else to try?

I've sometimes found that GPS units can get confused if the last place they mapped to was a long way away from where they are currently - works a bit better with mobile phones as they can be set to get an approximate fix from the signal tower or the internet... Where were you when the last photo you took with a fix was taken?

It happens. I once bought a second-hand A55 in mint condition, but I discovered pretty quickly that GPS didn't work. I knew what it should do because I already owned a properly working A55. I returned the camera to the seller and bought another one from someone else. (That one turned out to have a back-focus issue (which I fixed), but no problem with GPS.)

Is this a first time recent event? It's a remote possibility that space weather could be the culprit. Seems like the internet has been slow at times here the last couple days, I just now checked the SpaceWeather.com site and it seems we've been in a solar storm the past 5 days and are about to exit it, so maybe with the a77's weak GPS performance it can't lock on right now so maybe check again in a few days.
I also see there are 25 sun spots reported, little ones scattered about but enough for me to break out the solar filter.

Last photo with a fix was Feb 24th, only about 8 miles from here.
Next photo I took was April 6th, no GPS data on this or subsequent photos.

So much for my 'distance has confused it' theory..

Thanks for your observations, it's looking like it's failed.

Hi, I bought a second hand A77 and found out that if the gps assist file is out of date it takes forever to get a gps link. Just plug the camera to your PC with a USB cable after you installed the support software from SONY or do it manualy. Then gps works again.

Hi Ruud, that's not it, assistme.dat is auto-updated when I plug the card reader into the PC to grab the images.

Oh dear, that sucks big time. Maybe you can try one last thing, switch the camera on and wait outside in a open area until it get a fix. Sometimes gps takes much longer then normal to get a fix when it's not used for a while.

It may sound like "is there gas in the car?" advice but you never know.
