What is SmartphoneRTK ?

It is a Centimetre accurate external GNSS antenna device for your Android smartphone or tablet.

The technology is based on a multiband GPS, GLONASS, Beidou, Galileo receiver in combination with a RTK correction data received via internet from your local NTRIP provider. An App allows you to connect to this casters via internet and receive correction data. This data enable this GNSS chip to calculate your exact geolocation coordinates. These coordinates are automatically applied in single Apps like REDcatchs RTKcamera App or even streamed into your whole android system for any usage.

Easy to use and compatible to many Apps, you can do surveys or geotag photos (written into EXIF) for photogrammetry and documentation usage, traditional surveys, measure GCPs for drone surveys or stake out known points

Mock Location App

Android allow to “Mock” a Location. With this Apps you can modify the GPS location, for example by using the one from external antenna. The problem is, that “Developer Mode” has to be activated and the update rate is 1Hz only. But if you can live with this restrictions, you can use the RTK positions Android wide.
