After a couple of hours messing with various settings my Theta X is now configured to use A-GPS via an Android phone hotspot. Whilst this will hopefully give quicker positions from a cold start, and perhaps positions where GNSS alone may not work due to satellite geometry, I do not anticipate that t…

[image] Kevin_Hainsworth: see that the GNSS chip receives SBAS signals which would improve accuracy. How can you tell that the chip receives SBAS ? If it is more accurate, why wouldn’t all phone use SBAS? There must be some downside, right? It’s likely that this type of device could work wi…

The spec. sheet of the Ublox chipset and the Ricoh documentation indicates that it is SBAS capable. SBAS is a worldwide service primarily used in transportation tracking, approx. 3m accuracy as opposed to approx, 5m for GNSS, and is delivered in regional flavours, such as EGNOS in Europe, (where a s…

I’ll submit community feedback in a general report. Are you referring to this documentation? Reach the full potential of RICOH THETA X with built-in GPS l RICOH360 Blog In addition to support for GLONASS and MICHIBIKI (QZSS), THETA X also supports A-GPS (Assisted GPS), increasing its potential …

A-GPS is an internet based resource that in part speeds up the GNSS (GPS) initialisation process by providing an upto date ephemeris (listing of current and predicted satellite locations). A-GPS does not improve accuracy but is very helpful in obtainining and maintaining reliable GNSS locations. SB…

It might be more effective if you sent Cupix an email and asked them to inquire with RICOH if the SBAS can be added as an option to the THETA X. A clear use case or demand would help gather support. BTW, I installed this software inside of the THETA X. [image] Release v3.10.3 · barbeau/g…

Hi Craig, thanks for the suggestion, i will follow it up. The SBAS satellites are geo-stationary staellites ie. they stay in the same place wrt. the ground and they are simply communication satellites transmitting GNSS corrections from networks of ground stations, they do not transmit their own loca…

@Kevin_Hainsworth thanks for your help in explaining this. Just to be clear, I will include this in a report on community feedback. However, it would carry even more weight if a software partner like Cupix also made the request.

My thoughts on frame rate, GNSS and movement type in my Facebook post of 20230723 Ricoh THETA 360° Camera User Group | # Theta X for mapping | Facebook I feel there is a lot to improve in the useability of the X for Google Street View and Mapillary capture.

From your post I think it may be useful to write a case 6 type GPS information data packet instead of the case 5 type and add a case 7 type with the compass data. For the camm-spec What values are needed to improve the accuracy? How is the horizontal_accuracy and vertical_accuracy calculated? …

@Kevin_Hainsworth , I received information from RICOH on SBAS. It is enabled by default. “The RICOH THETA X built-in GPS has SBAS enabled by default. There is no way for customers to check exactly whether SBAS augmentation data is enabled, but if the position accuracy is around 3m in open sky (th…

That is good to hear. Thanks for taking the time to look into this. Here is a Linkedin post showing how I am using the theta X with CupixVista software Ricoh Theta X and CupixVista
They have some good ideas.
