Real time differential GPS with ArcGIS Runtime SDK?

OlivierROSSINI

Does ArcGIS Runtime SDK for Java (and others Runtime SDKs) support real time differential GPS (EGNOS and WAAS)?

Does it depend on the GPS receiver?

Does the SDK handle and apply the differential correction information (received through NMEA sentences)?

Any details about real time diffrential GPS with ArcGIS Runtime SDK is welcome.

If this is not supported in the SDK, is there an alternative approach (using third party SDK to handle real time differential correction)?

It depend on the GPS receiver. Nowadays it is quite common for new receivers to support real time differential GPS (EGNOS and WAAS). The receiver applies differential correction information and come up with better accuracy positions and report the position via NMEA. In Java SDK, you should be able to access FixStatus to determine if positions is differential corrected or not. If it is, FixStatus should be DIFFERENTIAL_GPS_FIX. If not, it will be <A href="https://developers.arcgis.com/java/api-reference/com/esri/core/gps/FixStatus.html#GPS_FIX" style="color: #8f309d; font-family: Arial, Helvetica, sans-serif; font-size: 12px;" rel="nofollow noopener noreferrer">GPS_FIX</A>
