Geotagging Photos
Quote from lateapex on May 13, 2024, 4:53 pmMy use case - automatically geotagging Canon R5 photos while hiking and traveling.
Current setup - QStarz BT-Q818XT, Samsung Galaxy S9, Bluetooth GNSS app, and Canon's Camera Connect. This works; my photos are GPS tagged as I take them. My issue is that it is not very accurate and there is considerable drift.
I also carry a Garmin GPSMap66i and the GPX logs it produces is a lot more accurate. I would love to use the GPSMap66i as my GPS source, but I don't think that is possible. I could not get GPS info from the 66i using Bluetooth GNSS or GPS Connector (on the Galaxy S9).
Would using the Columbus P-7 Pro provide better GPS tracks? (i.e. replace the BT-Q818XT with the P-7 Pro.)
Any other ideas?
Thanks,
Garrett

Yes, you can use the P-7 Pro with your Android phone for improved accuracy in photo geo-tagging. The P-7 Pro offers better accuracy than the BT-Q818XT.
If you're looking for significantly better accuracy (5 to 100 times improved), you might want to consider the Navisys GR-903 or the TOP608BT Bluetooth GNSS receivers as alternatives.

Thank you for your reply. If I can get down to 1/2 meter with the P-7 Pro, I would be very happy with that It looks like a good balance between performance and cost. Also, since a lot places where I hike does not have cell/internet service, I think that would mean needed a portable RTK base which would also add to the cost...
I try out the P-7 Pro...
Thanks again.

Quote from GPSWebShop Official on May 14, 2024, 11:59 amThe P-7 Pro has the following accuracy specifications: horizontal direction 0.5m CEP(50%) and 1.5m CEP(95%).
CEP stands for Circular Error Probable. A value of 0.5m CEP(50%) means that there is a greater than 50% probability that the track points will fall within a 0.5-meter radius. Similarly, a value of 1.5m CEP(95%) indicates that there is a greater than 95% probability that the track points will fall within a 1.5-meter radius.
I hope this provides a clearer description of the P-7 Pro's accuracy compared to simply stating a 0.5-meter accuracy.
Thanks!

While it is an improvement over the BT-Q818XT, the Garmin GPSMap66i still has less drift. The downside with the GPSMap66i is the inability to be used as a GPS source (with Bluetooth GNSS).
