A phone listing GPS and GLONASS supports a multi-system positioning specification; it should not be described as using only two satellites. The R4-T currently lists GPS, GLONASS, BDS, Galileo and QZSS. Those names do not establish a measured route accuracy or dual-frequency reception.
Define what the app must deliver
Write down whether the job needs turn guidance, a route track, geotagged photographs or an asset-location record. Include offline route files and the output format required by the receiving system.
- Confirm the exact device's positioning specification and required app permissions.
- Check that the planned route or map data is available before leaving connectivity.
- Run an approved representative route and retain the exported record.
- Inspect missing sections, timestamp behavior and attachment association.
Keep the evaluation within its scope
A successful route does not prove positioning performance in every location. Record device placement, software, conditions and the comparison method. If signal-band support or a specific accuracy threshold is mandatory, request separate documentation and a suitable acceptance procedure.
Current hardware source
Use the R4-T positioning specification as the starting point. This guide does not report a completed route trial and should not be used as evidence of survey-grade or safety-critical navigation performance.
