RTK GNSS for your smartphone

Easy to use – Centimetre Accuracy – Compatible to Android 10+

REDcatchs main field of application is Photogrammetry and 3D modelling…. but
it’s all up to you what you make of it!
We provide you with all necessary components, from hardware, optimization kits, variouse Apps and training/support.

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 an local NTRIP correction data reception from your local 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, plug&play and compatible to many Apps, you can do surveys or geotag photos for photogrammetry usage and many more. If you choose the Survey Edition, you can do traditional surveys, measure GCPs for drone surveys or stake out known points. The Photo Edition is designed to record photos with precise coordinates (written into EXIF) to do photogrammetry and documentation tasks.

What you may need to get started

Combine the packages for your personal need. Our suggestion: Do not forget the training, as this is crucial for best usage and your daily work. As a positive effect, the ROI will be definitely higher.

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.
