Hi @antony ! There’s two main factors on how accurate CHT data will be which are outside the control of the CHT: 1. Location at time of form input: If the handset is indoors or outside but behind large buildings, there’s a chance that GPS may not work or work poorly. 2. The performance of the mobile handset itself. Newer devices tend to work better and some [older devices](https://forum.communityhealthtoolkit.org/t/what-do-the-geolocation-collection-errors-mean-in-terms-of-actual-device-phone-settings/91/2) or devices with out of date software can take a while to get a GPS signal. Otherwise, when the GPS signal is found, the CHT is incredibly accurate. For example, you can see in our example [COVID workflow](https://docs.communityhealthtoolkit.org/exploring/covid-rdt-reference-app/#provision-1), there’s some JSON attached to the sample form with the `geolocation` field. This shows data with with [7 decimal places](https://gis.stackexchange.com/questions/8650/measuring-accuracy-of-latitude-and-longitude) (eg `"latitude": 5.3951438`) - well under a 1 meter accuracy (a software embellishment though, likely 10 meter accuracy is more realistic). To read more about our GPS data, see the `geo*` fields attached to forms and in our [telemetry](https://docs.communityhealthtoolkit.org/building/guides/performance/telemetry/). As well, [this forum](https://forum.communityhealthtoolkit.org/t/challenges-with-gps-data-collection/1744/13) post does a deep dive into some GPS specifics in relation to the CHT. Please let me know if this answers your question! --- _[View the full topic](https://forum.communityhealthtoolkit.org/t/accuracy-of-gps-data/4689)._
