Problems with iPad Pro 11 using Garmins Boating navigation. Intermittent loss of location.

My iPad Pro 11 loses positional info intermittently. I’ve searched for solutions online and have found older threads with similar issues, but no solutions. It appears the issues are with my current iPad Pro 11, because my iPhone and older iPads don’t suffer from this disfunction. My iPad Pro 11 does have wifi+cellular and therefore should incorporate a gps.

Has the author of the thread “GPS not working on iPad 11” pro with navionics. Dangerous for navigation”. ever found an answer?

iPad Pro, iPadOS 18

For marine and aviation applications, use of a dedicated GPS receiver is often recommended. While WiFi+Cellular models of iPad incorporate a GNSS receiver within the Cellular chipset - providing accurate position and velocity measurement for a moving iPad - we see occasional complaint similar to your own.

Occasional signal loss can be caused by many contributory factors. Boat construction (wood or composite - some composites, such as carbon fibre - can block signals), deck fittings (signal blocking - or multipath interference) and other electrical/radio devices (signal interference) combined with sub-optimal GNSS antenna location can all combine to cause loss of signal lock. Even a film of water on a surface that covers/shades the iPad can block GNSS signals.

For critical and below-deck marine applications, you would be best advised to consider use of an external GNSS receiver or repeater - as this allows the GNSS antenna/receiver to be placed in a better location. There are many from which to choose - wired or wireless (Bluetooth) are available. BadElf, Garmin GLO and GNS3000 receivers have good reputation.

I started using navionics with a very old iPad 2 and a badelf pro external gps.Used it for many years and never had a problem. The iPad is so old that it won’t update to latest iOS and consequently I cannot update my charts. Some years ago I bought another iPad (with internal gps) which, again, worked flawlessly. However, the screen intensity was insufficient to use in bright daylight. This is how I ended up with the iPad Pro 11.

I’ve tried to use the badelf as an external gps source, but the problem persists. I lose positional information, especially in remote areas. When I refresh the chart orientation several times, the position reestablishes itself.

Is it possible that on my new iPad Pro the internal gps source is still being used as a primary source, rather than the badelf, and if so, how do I switch is off

I still haven't resolved the problem. It appears to lose positioning when in remote areas, i.e. when cell service is unavailable. Unfortunately, I have now returned to civilization, all is working well and I am unable to verify this conclusion.

This will have to be a work in progress, to be resolved in next years boating season. Thanks for your help

Played around with location services, but that didn’t do any thing for me.
